Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Before the technical scheme of the embodiment of the application is described in detail, description is first made on the self-mobile device provided by the embodiment of the application. The self-moving device provided by the embodiment of the application can be any mechanical device capable of moving autonomously in the environment where the self-moving device is located, for example, a robot, a purifier, an unmanned vehicle and the like; the robot may include a sweeping robot, a glass wiping robot, a home accompanying robot, a greeting robot, an autonomous service robot, etc., which is not limited herein. Further, the embodiment of the application is not limited to the appearance form of the self-mobile device, and the shape of the self-mobile device can be different according to the different implementation forms of the self-mobile device. Taking the outline shape of the self-moving equipment as an example, the outline shape of the self-moving equipment can be irregular or regular; for example, the outer contour shape of the self-moving device may be a regular shape such as a circle, an ellipse, a square, a triangle, a drop shape, or a D shape, and other than the regular shape, it is called an irregular shape, such as an outer contour of a humanoid robot, an outer contour of a drone, or the like, which belongs to an irregular shape. These self-moving devices can collect environmental information in the working environment by means of sensors arranged on the device body of the self-moving device so as to construct an environmental map according to the collected environmental information, and navigate and avoid obstacles based on the constructed environmental map, and execute working tasks in the working environment.
In general, a line laser sensor or a radar sensor for collecting environmental information is disposed on top of the self-mobile device to construct an environmental map according to the collected environmental information, and a structured light module or a binocular camera is disposed in front of the self-mobile device, i.e. in a traveling direction, for detecting obstacle information in the working environment, and according to the constructed environmental map and the collected obstacle information, the self-mobile device can be guided to navigate and avoid obstacles so as to perform working tasks in the working environment. However, providing a sensor on top of the self-moving device increases the height of the self-moving device in the longitudinal direction, with certain limitations on performing work tasks in a low environment; moreover, the mode of combining the linear laser sensor or the radar sensor with the structured light module or the binocular camera has limited information acquired in unit time, and the functions of quickly constructing an environment map, accurately positioning, avoiding obstacles and the like of the self-mobile equipment are difficult to realize. Therefore, in order to meet the demand of users for lighter, thinner and more intelligent self-mobile equipment, the embodiment of the application provides the self-mobile equipment with a novel structure, wherein the side wall of the equipment body of the self-mobile equipment is correspondingly provided with an area array sensor in the advancing direction, and in the advancing process of the self-mobile equipment, the environment information of the area in front of the advancing direction is acquired through the detection information number emitted by the area array sensor.
In the embodiment of the application, the type and wavelength of the detection signal emitted by the area array sensor are not limited, for example, the type of the detection signal can be an infrared signal or a laser signal, and the laser signals are taken as examples, the wavelengths are different, the colors of the laser signals can be different, and the laser signals can be a red laser signal, a purple laser signal and the like. Further, the specific manner in which the area sensor collects information is not limited, and alternatively, information may be collected by a Time of Flight (TOF) method. Taking an area array TOF sensor as an example, in the travelling process of the self-mobile device, the area array TOF sensor can emit detection signals outwards in a projection mode, the detection signals reach the surface of an obstacle, a coverage area is formed on the surface of the obstacle, the detection signals passing through the surface of the obstacle can be reflected back, the distance between the obstacle and the self-mobile device can be determined according to the time difference between the emission and the receiving of the detection signals, and information corresponding to the coverage area of the detected signal on the surface of the obstacle can be acquired. Because the detection signals emitted outwards by the area array TOF sensor are projected to the surface of the obstacle in a projection mode, the farther the distance between the self-moving device and the obstacle is, the larger the projected detection signal area to the surface of the obstacle is, therefore, under the condition that a certain distance exists between the self-moving device and the obstacle can be detected, the self-moving device can collect information on the surface of the obstacle, and also can collect information such as outline, height and/or width corresponding to the obstacle, and the like, compared with the existing mode of collecting information by using a linear laser sensor or a radar sensor, the area array TOF sensor can collect more abundant environmental information in unit time, based on the information, the distance measurement, height measurement, identification and three-dimensional environment reconstruction can be performed on the low obstacle more accurately, the richness and the accuracy of the environmental information collected by the self-moving device are facilitated, the environmental map can be avoided or constructed more accurately by the self-moving device based on the collected environmental information, and the sensing capability and the intelligent level of the self-moving device on the operation environment are improved.
In the embodiment of the application, the specific arrangement position of the area array sensor on the side wall of the self-moving equipment body is not limited, and alternatively, the area array sensor can be arranged at the position right in front of, left in front of or right in front of the corresponding travelling direction; the field angle of the area array sensor comprises a vertical field angle and a horizontal field angle, and the field angles are different, so that the area array sensor corresponds to different field ranges. The embodiment of the application is not limited to a specific view angle corresponding to the area array sensor, the area array sensor with a proper view angle can be selected according to application requirements, and the angle between the transmitting direction and the horizontal plane of the detection signal transmitted by the central position of the area array sensor is not limited, for example, the detection signal can be parallel to the speaking plane or have any angle with the horizontal plane, and the detection signal can be specific according to the application requirements. FIG. 1a is a schematic diagram of a self-moving device in the traveling process, as shown in FIG. 1a, because the area array sensor is limited by the installation position and the angle of view when being installed and used at a fixed position on the self-moving device, the area array sensor has a certain effective measuring range, and the effective measuring range at least comprises a region between the blind area distance corresponding to the area array sensor and the farthest distance in the front region of the area array sensor; the blind area distance of the area sensor is the nearest distance, for example, 10cm, of the area sensor capable of detecting the obstacle information, and the area sensor cannot detect the obstacle information under the condition that the distance between the area sensor and the obstacle is smaller than 10 cm. In the embodiment of the present application, as shown in fig. 1b, a region where the area sensor cannot detect the obstacle information is referred to as a blind area range of the area sensor; the size of the blind area range is not limited, and is related to the installation position and the angle of view, the shape and the size of the area sensor on the self-mobile device, and the type of the sensor used.
Based on the above, the embodiment of the application provides an environmental information collection method, which can collect the obstacle information in the area in front of the travelling direction of the mobile device by using the area array sensor, and execute the leakage repairing action under the condition that the obstacle information cannot be collected when travelling to the end of the obstacle, and supplement and collect the obstacle information in the blind area range of the area array sensor, thereby being beneficial to further improving the richness and accuracy of the collected obstacle information and being capable of collecting the environmental information more comprehensively.
The environmental information collection method provided by the embodiment of the application is described in detail below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an environmental information collection method suitable for a self-mobile device according to an embodiment of the present application, where, as shown in fig. 2, the method includes:
s1, controlling the self-mobile device to travel along a first side surface of an obstacle, and acquiring obstacle information on the first side surface by using an area array sensor arranged in the traveling direction until the self-mobile device travels to a first position where the obstacle information on the first side surface cannot be acquired;
s2, executing a leak repairing action at the first position so that a second side surface of the barrier falls into the visual field range of the area array sensor, wherein the second side surface is adjacent to the first side surface;
And S3, controlling the self-mobile device to continue to travel along the second side surface, and continuously acquiring obstacle information on the second side surface by using the area array sensor.
In the embodiment of the application, in the traveling process of the self-mobile device, the area array sensor arranged in the traveling direction can be used for collecting the barrier information in the front area of the traveling direction, and when the area array sensor collects the barrier information, the collected barrier information is the barrier information on the surface of the barrier facing the side of the self-mobile device. In the embodiment of the application, the surface of the obstacle facing the side of the self-moving device is called a first side, the corresponding profile information of the first side can be determined based on the acquired obstacle information, the self-moving device can be controlled to travel along the first side of the obstacle according to the profile information, and the obstacle information on the first side can be acquired by utilizing the area array sensor. As can be seen from the above implementation, when the area array sensor detects environmental information, the area that can be detected by the emitted detection signal is limited by factors such as the shape, size, installation position and angle of view of the area array sensor, and the type of sensor used, so that the area array sensor has a blind area range, and the obstacle information method in the blind area range is acquired. As shown in fig. 3a, the obstacle is in the area sensor blind area range from the time the mobile device travels along the first side of the obstacle until the mobile device travels to the first position where the obstacle information on the first side cannot be acquired. In order to collect the obstacle information in the blind area range more abundantly and accurately, in the embodiment of the application, when the mobile device moves to the first position, the blind area range of the area sensor can be subjected to the leakage repairing action at the first position, so that the second side surface of the obstacle falls into the field of view of the area sensor, and then the obstacle information on the second side surface is collected, so that the obstacle information can be collected more comprehensively. As shown in fig. 3a, the second side is adjacent to the first side. Further, control continues to travel from the mobile device along the second side and continues to gather obstacle information on the second side using the area array sensor. In this way, the area array sensor can be used for supplementing and collecting the obstacle information on the second side surface in the blind area range, so that the mobile equipment can collect more abundant and complete obstacle information in the whole travelling process, avoid missing the obstacle information in the blind area range, and provide a foundation for obstacle avoidance and/or environment map construction in the subsequent operation process.
Here, the blind area range of the area sensor is related to the traveling direction of the self-mobile device, and the blind area range of the area sensor is different from the traveling direction of the self-mobile device, where the difference mainly means that the directions of the blind area ranges are different. In the embodiment of the application, the blind area range of the area array sensor can be understood as follows: in the direction of travel of the self-moving device, the area array sensor cannot detect the area in the effective range of the area array sensor. Based on the definition, if the area sensor detects an obstacle in a certain traveling direction of the self-mobile device, for convenience of description and distinction, when the traveling direction of the self-mobile device is recorded as a target traveling direction when the area sensor detects obstacle information, the area sensor can execute a leak repairing action on the blind area range of the area sensor in the target traveling direction outside the blind area range of the area sensor in the target traveling direction, and in the process of executing the leak repairing action, the area sensor is used for replenishing and collecting the obstacle information in the blind area range of the target traveling direction.
In the embodiment of the application, before the self-mobile device travels along the first side of the obstacle, the area array sensor can be used for acquiring the obstacle information in the front area in the current travelling direction, and if the obstacle exists in the front area in the travelling direction of the self-mobile device, the self-mobile device can travel along the first side of the obstacle from a proper position close to the first side of the obstacle in order to accurately and comprehensively acquire the obstacle information under the condition that the area array sensor acquires the obstacle information on the first side of the obstacle. As shown in fig. 3b, the self-moving device may travel to a second position near the first side, adjusting the direction of travel to travel along the first side of the obstacle. In the embodiment of the application, the specific position of the second position is not limited, and optionally, the second position close to the first side surface can be determined according to the obstacle avoidance distance and the blind area distance corresponding to the self-moving equipment, and the distance from the second position to the first side surface is slightly greater than or equal to the sum of the obstacle avoidance distance and the blind area distance so as to ensure that the self-moving equipment can normally travel and can acquire the obstacle information on the first side surface of the obstacle. Based on this, in the case of traveling from the mobile device to the second position, the traveling direction may be adjusted to any one of the extending line or tangential direction of the first side at the second position to travel along the first side of the obstacle.
Further, in the case where the self-moving device travels along the first side of the obstacle to the first position as shown in fig. 3a, the obstacle is within the blind zone of the self-moving device, and the self-moving device cannot collect the obstacle information on the first side. At this time, the self-moving device may perform a leak repairing action at the first position so that the second side of the obstacle falls within the field of view of the area array sensor. In the embodiment of the application, a specific mode of executing the leak repairing action from the mobile equipment is not limited, whether the first position is suitable for executing the leak repairing action or not can be determined in order to supplement the barrier information in the range of the acquisition blind area, the position can be adjusted under the condition that the first position is determined to be unsuitable for executing the leak repairing action, and then the leak repairing action is executed according to the adjusted position; in the case where it is determined that the first location is appropriate to perform the leak repairing action, the leak repairing action may be performed directly at the first location. In the embodiment of the application, the basis for determining whether the first position where the self-mobile device is located is suitable for executing the leak repairing action is as follows: the self-mobile device can not collide with the obstacle in the process of executing the leak repairing action, and can acquire the obstacle information in the blind area range.
The following description will be made regarding two cases where the first position is not suitable for performing the leak repairing operation and is suitable for performing the leak repairing operation.
Case 1: the first position is not suitable for performing a leak repairing action.
In this embodiment, in order to perform the leak repairing operation at a more suitable position, as shown in fig. 3c, before performing the leak repairing operation, the self-moving device may be controlled to move from the first position to a third position in a direction away from the first side, and perform the leak repairing operation at the third position, so that the second side of the obstacle falls within the field of view of the area array sensor. Optionally, whether the first position is suitable for performing the leak repairing action may be determined according to a distance between the first position and the first side, and if the distance between the first position and the first side is smaller than a blind area distance corresponding to the self-mobile device, it is determined that the first position is not suitable for performing the leak repairing action, in this case, the self-mobile device may be controlled to move from the first position to a third position in a direction away from the first side. In this embodiment, the specific relative positional relationship between the third position and the first position is not limited, the traveling direction of the self-mobile device is taken as the front direction, the third position may be in any direction of the left side, the left front, the right front or the right front of the first position, in order to ensure that the second side surface can fall within the field of view of the area array sensor during the execution of the leak repairing operation by the self-mobile device, the third position cannot be left rear or rear of the first position, and fig. 3c is illustrated by taking the left front of the first position as an example of the third position.
Further, the embodiment is not limited to a specific manner of controlling the movement of the self-moving device from the first position to the third position in a direction away from the first side, and alternatively, the self-moving device may be controlled to adjust the traveling direction at the first position so as to face the first side or the extension line thereof, and then controlled to retract to the third position along the opposite direction of the adjusted traveling direction; the mobile device may be controlled to move to the third position in a direction away from the first side, and then the mobile device is controlled to adjust the traveling direction at the third position to face the first side or the extension line thereof (as shown in fig. 3c and 3 d), which mode is specifically adopted, and may be flexibly selected according to the actual situation. For example, in the case where the self-moving device is rotatable in the first position and does not collide with the first side face of the obstacle, it may be moved from the first position to the third position in any one of the moving manners described above; in the case that the distance between the first position and the first side of the obstacle is relatively short, and the rotation of the self-moving device collides with the obstacle, the second moving mode can be selected, namely, the self-moving device moves to the third position first, and then the direction is adjusted at the third position. In the present embodiment, the direction of travel is not limited to the rotation angle when the self-moving device adjusts to face the first side surface or the extension line thereof, but may alternatively be any angle between 90 ° and 120 °, and the rotation angle of the self-moving device may be different according to the difference of the relative positional relationship between the third position and the first position.
Case 2: the first location is adapted to perform a leak repairing action.
In this embodiment, in the case where the distance from the first position to the first side surface is greater than the blind area distance corresponding to the self-mobile device, the self-mobile device can acquire the obstacle information of the obstacle side surface at the first position and does not collide with the obstacle, so it can be determined that the first position is suitable for executing the leak repairing action. In this embodiment, a specific manner of determining that the first position is suitable for executing the leak repairing action is not limited, and optionally, before executing the leak repairing action, the distance from the first position to the first side may be calculated to be greater than the blind area distance corresponding to the self-mobile device according to the acquired obstacle information of the first side; alternatively, before the leak repairing operation is performed, the self-mobile device may be controlled to rotate several times at the first position, so that it is determined that the self-mobile device does not collide with the obstacle and can collect the obstacle information, and the angle of rotation of the self-mobile device at the first position is not limited, and may be any angle between 90 ° and 120 °. Further, in the event that the first location is determined to be suitable for performing the leak repairing action, the self-moving device may be controlled to perform the leak repairing action at the first location such that the second side of the obstacle falls within the field of view of the area array sensor.
It should be noted that, in the embodiment of the present application, the relative positional relationship between the first position and the obstacle is not limited, and alternatively, the first position may be a starting position where the obstacle information on the first side cannot be acquired in the process of traveling along the first side of the obstacle from the mobile device, or any position after the starting position. Further, the embodiment of the present application is not limited to a specific manner of determining the first position, and alternatively, in controlling the traveling from the mobile device along the first side of the obstacle, the area array sensor disposed in the traveling direction may be used to collect the obstacle information on the first side, and as shown in fig. 3e, when the end position of the first side is identified according to the collected obstacle information on the first side, the mobile device may be controlled to continue to move forward for a specified distance until reaching the first position. In the embodiment of the application, the specific value of the specified distance for continuing to move forward from the end position of the first side surface of the mobile device is not limited, and alternatively, the specified distance can be larger than the blind area distance of the area array sensor or smaller than the sum of the obstacle avoidance distance and the blind area distance of the mobile device.
It should be further noted that, regarding the specific location where the leak repairing action is performed, the embodiments of the present application are not limited, and the above examples are only illustrative. In the embodiment of the present application, before the execution of the leak repairing operation, whether the first position is suitable for executing the leak repairing operation may be not determined, and in the case of traveling from the first position to the first position, the leak repairing operation may be executed at the third position by default while moving from the first position to the third position in a direction away from the first side.
In the embodiment of the present application, the specific manner of performing the leak repairing action at the first position or the third position by the self-moving device is not limited, and alternatively, the self-moving device may perform any one of a plurality of actions such as in-situ rotation, differential rotation, movement in a plurality of directions, or movement in another direction different from the current traveling direction at the first position or the third position, and the collecting of the obstacle information on the second side of the obstacle in the blind area is supplemented. Each of the leak repairing actions that may be performed from the mobile device is illustrated below:
leak repairing action 1: the self-moving device rotates in place at the first position or the third position. In this embodiment, the detection range of the area array sensor may be changed by the in-situ rotation of the self-mobile device, and as the self-mobile device rotates, the detection range of the area array sensor is continuously changed, and the obstacle information on the second side surface in the blind area range before the in-situ rotation of the self-mobile device may be detected. Here, the rotation direction of the self-moving device is not limited, and the self-moving device may be rotated clockwise or counterclockwise. Since the area sensor emits the detection signal in a projection manner, the area sensor rotates on the self-moving device In the rotating process, the detection signal can also rotate along the rotating direction, and in the rotating process, the detection signal can detect the blind area range of the area array sensor before the self-moving equipment starts to rotate along the rotating direction, so that the purpose of supplementing and collecting the obstacle information of the area array sensor in the blind area range before the self-moving equipment starts to rotate is achieved. In the embodiment of the application, the number of in-situ rotation turns of the self-moving equipment is not limited, and along with the increase of the number of rotation turns of the self-moving equipment, the richness of the obstacle information on the second side surface of the obstacle which can be detected also increases, and the self-moving equipment can set a threshold value of the number of rotation turns to control the number of rotation turns of the self-moving equipment according to specific operation conditions. Further alternatively, the relationship between the distance between the self-moving device and the obstacle during the execution of the leak repairing action is not limited, for example, the self-moving device may stop rotating in place at the first position or the third position, or may rotate while moving toward the obstacle when the distance is greater than the dead zone distance of the area array sensor, and may be controlled according to the specific operation condition, and is not limited too much.
Leak repairing action 2: the self-moving device performs differential rotation at the first position or the third position. In this embodiment, differential rotation refers to alternating left and right rotation of the self-moving device in place about its central axis perpendicular to the ground. The detection range of the area array sensor can be changed through in-situ differential rotation of the self-moving device, and the detection range of the area array sensor is changed continuously along with the differential rotation of the self-moving device, so that the obstacle information on the second side face of the area array sensor in the blind area range before the in-situ differential rotation of the self-moving device can be detected. Here, the number of times of left-right rotation of the self-mobile device is not limited, and for example, the self-mobile device may be rotated once left and then rotated once right, or may be rotated once left and then rotated once right; further, the frequency of left-right rotation from the mobile device is not limited, and for example, the frequency of left-right rotation from the mobile device may be the same or different; further, the angle of left-right rotation from the mobile device is not limited, for example, the mobile device may be left or rightRotated by 30 °, 60 °, 90 °, 180 °, etc., respectively. Because the area array sensor transmits the detection signal in a projection mode, the detection signal can rotate along the rotation direction in the differential rotation process of the self-moving equipment, and the detection signal can detect the blind area range of the area array sensor before the self-moving equipment starts to rotate along the rotation direction in the differential rotation process, so that the purpose of supplementing and collecting the obstacle information of the area array sensor in the blind area range before the self-moving equipment starts to rotate is achieved. In the embodiment of the application, the number of in-situ differential rotation of the self-moving device is not limited, and as the number of differential rotation of the self-moving device increases, the richness of the obstacle information which can be detected also increases, and the self-moving device can set a threshold value of the number of differential rotation to control the number of differential rotation of the self-moving device according to specific operation conditions. Further alternatively, the relationship between the distance between the self-moving device and the obstacle during the execution of the leak repairing operation is not limited, for example, the self-moving device may stop performing the in-situ differential rotation at the first position or the third position, or may move to the obstacle while performing the differential rotation when the distance is greater than the dead zone distance of the area array sensor, and may be controlled according to the specific operation condition, without being excessively limited.
Leak repairing action 3:the slave mobile device moves in multiple directions from the first position or the third position. In this embodiment, the detection range of the area sensor may be changed when the self-moving device moves in multiple directions, and as the self-moving device moves and changes in direction, the detection range of the area sensor is continuously changed, and the obstacle information on the second side of the area sensor in the blind area range before the self-moving device moves in multiple directions may be detected. Here, the direction of the self-moving device is not limited to be specific, so long as the direction of the self-moving device can be changed, and in the moving process of the self-moving device, the detection signal can detect the blind area range of the area array sensor before the self-moving device moves, so that the purpose of supplementing and collecting the obstacle information on the second side surface of the area array sensor in the blind area range before the self-moving device moves is achieved. For example, a self-moving deviceThe device can keep the direction right in front of the device unchanged and move left and right along the horizontal direction vertical to the right in front of the device; alternatively, the self-moving device may move toward the obstacle in a "Z" or "S" trajectory; alternatively, the self-moving device may move along any irregular track, etc. Since the area array sensor emits the detection signals in a projection manner, the direction of the detection signals can be changed along the moving direction in the process of moving the area array sensor from the mobile device to a plurality of directions, and then the detection signals can detect the blind area range of the area array sensor before moving the area array sensor from the mobile device, and the obstacle information in the blind area range is collected.
Leak repairing action 4:the self-moving device moves in another direction different from the current traveling direction at the first position or the third position. In this embodiment, the detection range of the area sensor may be changed by moving the self-moving device in the other direction different from the current traveling direction, and as the detection range of the area sensor is changed continuously by the movement and the change of the direction of the self-moving device, the obstacle information on the second side of the area sensor may be detected in the blind area range before the self-moving device moves in the other direction different from the current traveling direction. Here, the direction of the self-moving device is not limited to be specific, so long as the direction of the self-moving device can be changed, and in the moving process of the self-moving device, the detection signal can detect the blind area range of the area array sensor before the self-moving device moves, so that the purpose of supplementing and collecting the obstacle information on the second side surface of the area array sensor in the blind area range before the self-moving device moves is achieved. For example, the center axis of the self-moving device along the front may be used as a dividing line, and the self-moving device may move to the left side of the current traveling direction or may move to the right side of the current traveling direction. Since the area sensor emits the detection signal in a projection manner, the direction of the detection signal is also changed along the moving direction in the process of moving from the mobile device to the other direction different from the current traveling direction, and then the detection signal can detect the blind area range of the area sensor before moving from the mobile device and acquire the obstacle information in the blind area range.

In the embodiment of the present application, the moving speed of the self-moving device when the self-moving device is in a direction from the first position to the first side far away from the obstacle is not limited, for example, the self-moving device may be far away from the obstacle in a uniform manner, and may also be far away from the obstacle in a non-uniform manner, where the non-uniform manner includes, but is not limited to: the deceleration mode or the acceleration mode may be uniform deceleration or non-uniform deceleration, and the acceleration mode may be uniform acceleration or non-uniform acceleration. Accordingly, in the embodiment of the present application, the moving speed when the self-moving device moves from the leak repairing position where the leak repairing action is performed to the fourth position to approach the obstacle is also not limited, for example, the self-moving device may approach the obstacle in a uniform manner, or approach the obstacle in a non-uniform manner, where the non-uniform manner includes but is not limited to: the deceleration mode or the acceleration mode may be uniform deceleration or non-uniform deceleration, and the acceleration mode may be uniform acceleration or non-uniform acceleration.
In the embodiment of the application, the self-mobile device can avoid the obstacle according to the acquired and previously acquired obstacle information for executing the leakage repairing action and/or construct an environment map according to the acquired and previously acquired obstacle information for executing the leakage repairing action in the process of travelling along the side surface of the obstacle and acquiring the obstacle information. In the embodiment of the application, a specific mode of obstacle avoidance by the self-mobile device according to the acquired and previously acquired obstacle information for executing the leakage repairing action is not limited, and optionally, a first travelling path bypassing the obstacle can be planned according to the acquired and previously acquired obstacle information for executing the leakage repairing action, and travelling is continued along the first travelling path until bypassing the obstacle; when planning the first travel path around the obstacle, the points on the acquired obstacle can be determined according to the acquired and previously acquired obstacle information for executing the leak repairing action, the points on the acquired obstacle are expanded, the boundary profile of the obstacle is determined based on the points on the expanded obstacle, and the first travel path around the obstacle is planned according to the boundary profile.
Accordingly, the specific mode of constructing the environment map from the mobile device according to the acquired and previously acquired obstacle information for performing the leak repairing operation is not limited, and optionally, as shown in fig. 3g, a second travel path surrounding the obstacle may be planned and moved along the second travel path surrounding the obstacle according to the acquired and previously acquired obstacle information for performing the leak repairing operation; continuously acquiring obstacle information by using an area array sensor in the process of moving around the obstacle to obtain complete information of the obstacle, and marking the complete information of the obstacle in an environment map; in planning a second travel path around the obstacle, points on the acquired obstacle may be determined based on the acquired and previously acquired obstacle information from performing the leak repairing action, the points on the acquired obstacle may be inflated, a boundary profile of the obstacle may be determined based on the inflated points on the obstacle, and the second travel path around the obstacle may be determined based on the boundary profile and the edge mode of the self-moving device.
The following describes a path planning and/or obstacle avoidance process of the self-mobile device according to the acquired obstacle information for different scenes.
Scene example 1:
in this embodiment, after the area array sensor is used to supplement the acquired obstacle information in the blind area range in the process of executing the leak repairing action, the self-mobile device may further plan a first travel path around the obstacle according to the supplement acquired and previously acquired obstacle information, and continue traveling along the first travel path until the obstacle is bypassed; wherein the obstacle is an obstacle corresponding to the supplemental acquired and previously acquired obstacle information. According to the method and the device for detecting the obstacle, the self-moving equipment can acquire complete information of the obstacle on one side of the self-moving equipment according to the obstacle information detected in the normal moving process and the obstacle information in the blind area range which is acquired in the process of executing the leak repairing action, based on the complete information, a first moving path bypassing the obstacle can be determined, and the moving is continued along the first moving path until the obstacle is bypassed, so that the obstacle avoidance purpose is realized.
In the embodiment of the present application, the implementation of planning the first travel path around the obstacle according to the acquired and previously acquired obstacle information by the self-mobile device is not limited. In an alternative embodiment, points on the acquired obstacle may be determined from the supplemental acquired and previously acquired obstacle information, the points on the acquired obstacle may be inflated, a boundary profile of the obstacle may be determined based on the inflated points on the obstacle, and a first travel path around the obstacle may be planned according to the boundary profile. For example, taking the case of supplementing the obstacle information in the range of the acquisition blind area by using the self-mobile device in a differential rotation mode, the self-mobile device determines points on the acquired obstacle according to the acquired and previous acquired obstacle information, expands the points on the acquired obstacle, and determines the boundary profile of the obstacle based on the points on the expanded obstacle; further, planning a first travel path from the mobile device according to the determined boundary contour of the obstacle and providing for continued travel along the first travel path may bypass the obstacle.
In the embodiment of the application, the expansion degree of the point on the obstacle is not limited, and in order to ensure that the self-moving device does not collide with the obstacle when traveling in the edge mode, the minimum degree of expansion is not smaller than the obstacle avoidance distance of the self-moving device. After the self-moving device detects the boundary of the obstacle, the points on the detected obstacle can be expanded to obtain the boundary outline of the obstacle, and further, the self-moving device can move towards the obstacle to reach the position of the boundary outline and continue to travel along the boundary outline in a right edge mode or a left edge mode until the self-moving device travels to the boundary of the obstacle, and no obstacle information is detected in the advancing direction of the self-moving device, namely, the self-moving device bypasses the obstacle.

In the embodiment of the application, the direction of selecting the first travel path from the mobile device is not limited either, the mobile device can determine that the side of the obstacle boundary is the direction of the first travel path for the first time, and after the side of the obstacle is detected by the leak repairing action, one side is selected as the direction of the first travel path, or one side which is easier to bypass the obstacle is selected as the direction of the first travel path according to the environmental information around the side of the obstacle, and the limitation is not excessively made.
Scene example 2:
in this embodiment, after the area sensor is used to supplement the acquired obstacle information in the blind area range during the process of performing the leak repairing action, the self-moving device may plan a second travel path around the obstacle according to the supplement acquired and previously acquired obstacle information, and move around the obstacle along the second travel path, and continuously acquire the obstacle information by using the area sensor during the process of moving around the obstacle to obtain the complete information of the obstacle, and mark the complete information of the obstacle in the environment map; wherein the obstacle is an obstacle corresponding to the supplemental acquired and previously acquired obstacle information.
In the embodiment of the application, the self-mobile device can obtain the rough outline information of the obstacle according to the obstacle information detected in the normal travelling process and the obstacle information in the blind area range which is additionally acquired in the process of executing the leak repairing action, and based on the rough outline information, a second travelling path surrounding the obstacle can be planned and the self-mobile device can travel around the obstacle along the second travelling path. Further, the self-mobile device can continuously acquire obstacle information by using the area array sensor in the process of traveling around the obstacle to obtain complete information of the obstacle, and the acquired complete information of the obstacle is marked in the environment map to be used for constructing the environment map or updating the existing environment map.
In an embodiment of the present application, the implementation of planning the second travel path around the obstacle according to the supplementary acquired and previous acquired obstacle information from the mobile device is not limited, and in an alternative embodiment, the points on the acquired obstacle may be determined according to the supplementary acquired and previous acquired obstacle information, the points on the acquired obstacle may be expanded, the boundary profile of the obstacle may be determined based on the points on the expanded obstacle, and the second travel path around the obstacle may be planned according to the boundary profile. For example, taking the case of supplementing the obstacle information in the range of the acquisition blind area by using the self-mobile device in a differential rotation mode, the self-mobile device determines points on the acquired obstacle according to the acquired and previous acquired obstacle information, expands the points on the acquired obstacle, and determines the boundary profile of the obstacle based on the points on the expanded obstacle; further, a second travel path is planned from the mobile device according to the determined boundary contour of the obstacle, and travel is continued along the second travel path.
In the embodiment of the application, the mode of planning the second travel path around the obstacle by the self-mobile device is not limited, the self-mobile device can plan the second travel path first and then travel along the planned second travel path, and the second travel path can be planned while traveling, so that excessive limitation is not required. In the embodiment of the application, the direction of selecting the second traveling path from the mobile device is not limited either, the mobile device can determine that the side of the boundary of the obstacle is detected for the first time as the direction of the second traveling path, or after the boundary of the two sides of the obstacle is detected through the leak repairing action, one side is selected as the direction of the second traveling path, or according to the environmental information around the boundary of the two sides of the obstacle, one side which is easier to bypass the obstacle is selected as the direction of the second traveling path, and the limitation is not excessively performed.
Further, in order to ensure that the self-mobile device does not collide with the obstacle in the process of going around the obstacle in the edge mode, the self-mobile device can continuously detect the obstacle by using the area array sensor in the process of going, and a second running path planned by taking the boundary outline of the obstacle as a reference is updated at any time according to detected obstacle information, so that the running direction is adjusted. When the mobile equipment moves to the end and the obstacle information cannot be detected in the forward direction of the mobile equipment, the mobile equipment can continue to execute the leakage repairing action to guide the detection of the obstacle information, and a second planned travel path taking the boundary outline of the obstacle as a reference is updated according to the detected obstacle information, so that a new second travel path is obtained; further, the self-moving device can adjust the direction according to the updated second travelling path, achieve the purpose of travelling around the obstacle, and continue travelling along the obstacle in the right-edge mode or the left-edge mode adopted in the previous travelling; when the other end of the obstacle is reached, the direction can be adjusted in the same way, and the travel along the obstacle in the right edge mode or the left edge mode adopted in the previous travel is continued until the starting point of the travel along the second travel path is reached, so that the obstacle is surrounded. Further, after the mobile device travels around the obstacle along the second travel path for one circle, complete obstacle information can be acquired, an environment map can be constructed based on the acquired complete obstacle information, or an existing environment map can be updated, so that a foundation is provided for subsequent operation and obstacle avoidance.
Scene example 3:
in this embodiment of the scene, taking the case that the self-moving device is a sweeping robot, the sweeping robot is provided with an area array sensor. When the sweeping robot executes a sweeping task, the area array sensor can be used for collecting obstacle information in the forward direction, and obstacle avoidance is performed based on the collected obstacle information. The process of the sweeping robot performing the sweeping task will be described with reference to fig. 4 a.
As shown in fig. 4a, the process of the sweeping robot performing the sweeping task includes:
step 41a, when the sweeping robot receives the sweeping command, the sweeping robot starts to execute the sweeping task.
Step 42a, collecting obstacle information in the forward direction by using the area array sensor in the process of executing the cleaning task.
Step 43a, when it is detected that there is an obstacle in the forward direction thereof, the sweeping robot may travel at a reduced speed to a second position near the first side of the obstacle, and adjust the traveling direction at the second position to travel along the first side of the obstacle.
And 44a, executing a leakage repairing action to supplement and collect the obstacle information on the second side of the obstacle when the robot moves to a first position where the obstacle information of the first side cannot be collected along the first side of the obstacle, wherein the second side is in the blind area range of the area array sensor.
Step 45a, a first travel path of the obstacle is bypassed based on point plans on the obstacle acquired before and after the leakage repairing action, the robot travels along the first travel path, and obstacle information on the travel path is continuously acquired by using an area array sensor, so that whether the robot bypasses the obstacle is judged.
Step 46a, if an obstacle is detected in the forward direction of the sweeping robot, continuing to travel along the first travel path until no obstacle is detected, i.e. bypassing the obstacle, and continuing to perform the sweeping task.
In this embodiment, the sweeping robot may perform a sweeping task after receiving a sweeping instruction, and continuously detect whether an obstacle exists in a forward direction of the sweeping robot by using the area array sensor during the sweeping task, and when the obstacle is detected in the forward direction of the sweeping robot, the sweeping robot may travel to a second position near a first side of the obstacle, where a distance from the second position to the first side is slightly greater than or equal to a sum of an obstacle avoidance distance and a blind area distance, that is, is outside a blind area range of the area array sensor; further, the sweeping robot may adjust the traveling square at the second position to travel along the first side of the obstacle, and perform a leak repairing action for the blind area range of the area array sensor when traveling to the first position where the obstacle information of the first side is not acquired, so that the second side of the obstacle is within the field of view of the area array sensor. In this embodiment, the mode of the floor sweeping robot for performing the leak repairing action is not limited, the floor sweeping robot may use any leak repairing action mode in the above embodiment to supplement and collect the obstacle information in the area sensor blind area range, and the specific process of performing the leak repairing action may refer to the above embodiment and will not be described herein.
Further, the robot for sweeping the floor can confirm the point on the obstacle according to the supplementary collected and previous collected obstacle information, expand the point on the collected obstacle, confirm the boundary outline of the obstacle based on the point on the obstacle after expansion. Further, according to the boundary profile, the sweeping robot may plan the first travel path around the obstacle, and for the specific manner of expanding and planning the first travel path based on the point on the obstacle, reference may be made to the content of the above embodiment, which is not repeated here.
Further, the sweeping robot can travel along the first travel path after determining the travel direction, and continuously detect obstacle information by using the area array sensor in the travel process so as to judge whether the sweeping robot bypasses the obstacle. The distance between the first travelling path along which the sweeping robot travels and the obstacle is smaller than the effective range of the sweeping robot, so that the sweeping robot can continuously detect the obstacle in the travelling process. When the sweeping robot travels to the boundary of the obstacle and no obstacle information is detected in the forward direction of the sweeping robot, the distance between the sweeping robot and the obstacle is beyond the effective range of the sweeping robot, namely the sweeping robot bypasses the obstacle at the moment. Further, the sweeping robot can continue to travel in the forward direction, and the sweeping task is executed. If the sweeping robot can continuously detect the obstacle in the running process, the obstacle is still in the effective range of the sweeping robot, namely the sweeping robot does not bypass the obstacle yet. Thus, the sweeping robot may continue to travel along the first travel path and continue to detect the obstacle until no obstacle is detected in its forward direction, i.e. the sweeping robot has reached the obstacle boundary and bypassed the obstacle. Further, the sweeping robot can continue to travel in the forward direction, and the sweeping task is performed.
Scene example 4:
in this embodiment of the scene, taking the case that the self-moving device is a sweeping robot, the sweeping robot is provided with an area array sensor. The robot can utilize the area array sensor to gather the obstacle information in the forward direction in the process of executing the cleaning task, and on the one hand, the robot can avoid the obstacle based on the collected obstacle information, and on the other hand, the robot can also construct the environment map according to the collected obstacle information under the condition that the environment map is not constructed or the obstacle information does not exist on the environment map. The process of constructing an environment map while the sweeping robot performs the sweeping task will be described with reference to fig. 4 b.
As shown in fig. 4b, the process of constructing an environment map while the sweeping robot performs a sweeping task includes:
step 41b, when the sweeping robot receives the sweeping command, the sweeping robot starts to execute the sweeping task.
Step 42b, collecting obstacle information in the forward direction by using the area array sensor in the process of executing the cleaning task.
43b, when an obstacle is detected to exist in the forward direction, the sweeping robot judges whether the distance between the current position and the obstacle is far greater than the sum of the blind area distance and the obstacle avoidance distance corresponding to the self-moving equipment; if the distance is far greater than the sum of the dead zone distance and the obstacle avoidance distance, the robot is far away from the obstacle; if the distance is smaller than the blind area distance, the robot is close to the obstacle.
Step 44b, decelerating to a second position close to the first side of the obstacle when the sweeping robot is far away from the obstacle, backing to the second position close to the first side of the obstacle when the sweeping robot is close to the obstacle, and adjusting the traveling direction at the second position to travel along the first side of the obstacle; the distance from the second position to the first side surface is slightly greater than or equal to the sum of the obstacle avoidance distance and the blind area distance.
And 45b, executing a leakage repairing action when the robot moves to a first position where the obstacle information on the first side cannot be acquired along the first side of the obstacle, so as to supplement points of the acquired obstacle in the blind area range of the area array sensor before executing the leakage repairing action, and planning a second moving path around the obstacle based on the points on the obstacle acquired before and after the leakage repairing action.
Step 44b, the sweeping robot travels along the second travelling path, and continuously detects the obstacle by using the area array sensor, so as to judge whether the sweeping robot winds around the obstacle or collides with other obstacles.
Step 47b, if the robot has not completed winding the obstacle and has not touched other obstacle information, determining whether the robot has traveled to a boundary point (i.e., a dead end) of the second travel path; if yes, go to step 45b again; if not, go to step 48b.
Step 48b, continuing to travel along the second travel path until the obstacle is completed or other obstacles are bumped, and then entering step 49b.
Step 49b, performing obstacle recognition based on the obstacle information acquired by surrounding the obstacle and constructing an environment map under the condition that the robot bypasses the obstacle or collides with other obstacles.
Step 410b, after the robot winds around the obstacle, the cleaning task may be continuously executed until the cleaning task is executed.
In this embodiment, the sweeping robot may perform a sweeping task after receiving a sweeping instruction, and continuously detect whether an obstacle exists in a forward direction thereof by using the area array sensor during the sweeping task. When an obstacle is detected in the forward direction thereof, the sweeping robot judges the distance between the current position and the obstacle. If the sweeping robot judges that the current position is far away from the obstacle, the current position is unsuitable for collecting obstacle information or the effect of collecting the obstacle information is poor, and the sweeping robot can travel to a second position close to the first side surface of the obstacle in a decelerating manner; if the sweeping robot judges that the current position is very close to the obstacle, the sweeping robot at the current position can not acquire the obstacle information or has poor effect of acquiring the obstacle information, and can retreat to a second position close to the first side surface of the obstacle; the distance from the second position to the first side surface is slightly larger than or equal to the sum of the obstacle avoidance distance and the blind area distance, namely, the proper position corresponding to the acquired obstacle information. Further, the traveling direction may be adjusted at the second position to travel along the first side of the obstacle, and the area array sensor is used to continuously collect the obstacle information on the first side during traveling until the traveling is performed to the first position where the obstacle information on the first side cannot be collected, the leak repairing action is performed to supplement the point of the collected obstacle in the area array sensor blind area range before the leak repairing action is performed, and a second traveling path around the obstacle is planned based on the point of the collected obstacle before and after the leak repairing action.
In this embodiment, the mode of the sweeping robot to perform the leakage repairing action is not limited, the sweeping robot may use any leakage repairing action mode in the above embodiment to supplement and collect the obstacle information in the area sensor blind area range, and the specific process of performing the leakage repairing action may refer to the above embodiment and will not be described herein.
Further, the robot for sweeping the floor can obtain rough outline information of the obstacle according to the acquired and the acquired obstacle information, expand the points on the acquired obstacle, and determine the boundary outline of the obstacle based on the points on the expanded obstacle. Further, according to the boundary profile, the sweeping robot may plan the second travel path around the obstacle, and for a specific manner of expanding and planning the second travel path based on the point on the obstacle, reference may be made to the above-mentioned embodiments, which will not be repeated herein.
Further, the sweeping robot can travel along the second travel path and continuously detect obstacle information by using the area array sensor in the travel process so as to judge whether the sweeping robot winds up the obstacle. In the process of the travel of the sweeping robot, if the obstacle can be continuously detected in the forward direction of the sweeping robot, the sweeping robot is not wound around the obstacle, so the sweeping robot continues to travel along the second travel track, and the area array sensor is used for continuously detecting the obstacle. If no obstacle is detected in the forward direction of the robot during the travel of the robot along the second travel path, the robot is said to have reached the obstacle boundary at this time, and the obstacle is considered to have been wound. In the process, the sweeping robot can also judge whether the robot travels to the boundary point of the second path, if the obstacle is not wound at the boundary point of the second path, the robot can execute the leakage repairing action again, and re-plan the new second travel path, continue to travel along the new second travel path until the obstacle is wound, obtain complete obstacle information, and construct an environment map based on the complete obstacle information.
Here, the present embodiment is not limited to the execution sequence of steps 49b and 410b, for example, after the obstacle is wound, the cleaning task may be continuously executed until the cleaning task is completed, and then the environment map may be constructed or updated according to the collected complete obstacle information; or after the obstacle is wound, constructing or updating an environment map according to the complete obstacle information, and continuing to execute the cleaning task after constructing or updating the environment map; or after the obstacle is wound, continuing to execute the cleaning task, and constructing or updating the environment map according to the acquired complete obstacle information.
Further, if the robot collides with other obstacles in the travelling process, the obstacle can be detected and information of the obstacle can be acquired, and then an environment map is constructed based on the information of the obstacle acquired by surrounding the obstacle and the information of the object acquired by detecting other obstacles, so that a foundation is provided for executing work tasks and avoiding the obstacle subsequently. In the embodiment, the detection mode of the sweeping robot after hitting other obstacles in the process of going around the obstacles is not limited, and the sweeping robot can flexibly process according to specific working environments. For example, in the case where the working environment is relatively wide, the robot for sweeping floor may detect other obstacles around after traveling around the current obstacle is completed; the method can also detect other obstacles in a surrounding way under the condition of colliding with other obstacles, and then continue to detect the previous obstacle in a surrounding way; it is also possible to detect an obstacle in the event of a collision with another obstacle and to bypass the obstacle in dependence on the detection result. Or under the condition that the working environment is relatively narrow, if the sweeping robot cannot continue to travel after colliding with other obstacles in the process of traveling around the current obstacle, an alarm can be sent to a user. For example, by flashing an indicator light, buzzing an alarm, outputting voice, sending a prompt message to a user terminal, etc. Further, after the robot detects the obstacle information, the robot can continue to execute the cleaning task until the task is finished.
In the embodiment of the application, the self-mobile device can acquire the barrier information on the first side by using the area array sensor in the process of travelling along the first side of the barrier, and when travelling to the condition that no barrier information can be acquired, the self-mobile device can execute the leakage repairing action at the current position to supplement and acquire the barrier information in the blind area range of the area array sensor, namely supplement and acquire the barrier information on the second side adjacent to the first side, so that the self-mobile device can detect richer and more accurate environmental information in the process of executing the task, and the barrier information is prevented from being missed. Furthermore, according to the detected obstacle information, obstacle avoidance and environment map construction can be realized, and a foundation is provided for subsequent execution of work tasks and obstacle avoidance.
It should be noted that, the above embodiment is described by taking the case of setting the area array sensor on the self-mobile device as an example, however, the embodiment of the present application may also be applied to the self-mobile device with other types of sensors, and based on this, the embodiment of the present application further provides an environmental information collection method, where the method is applied to the self-mobile device, and the type of the sensor used by the self-mobile device is not limited. Fig. 4c is a flowchart of the environmental information collection method, as shown in fig. 4c, the method includes:
S1c, controlling the self-mobile device to travel along a first side surface of the obstacle, and acquiring obstacle information on the first side surface by using a sensor arranged in the traveling direction until the self-mobile device travels to a first position where the obstacle information on the first side surface cannot be acquired;
s2c, executing a leak repairing action at the first position so that a second side surface of the barrier falls into the field of view of the sensor, wherein the second side surface is adjacent to the first side surface;
and S3c, controlling the self-mobile device to continue to travel along the second side surface, and continuously acquiring obstacle information on the second side surface by using the sensor.
For specific processes of how the self-mobile device collects the obstacle information by using the sensor, performs the leak repairing action for the blind area range, and how to avoid the obstacle and plan the path according to the collected obstacle information, refer to the content of the above embodiments, and will not be described herein again.
