In order to solve the technical problems that the running track of the self-moving device is disordered and the efficiency is low due to the method in the prior art, the application provides a region identification method, the self-moving device and a computer readable storage medium, and the region boundary is identified by controlling the self-moving device to divide regions, so that the running track of the self-moving device is more regular, and the region boundary is identified more efficiently, and the method is described in detail in the following embodiments one by one.

First, the self-moving apparatus to which the present application relates is schematically explained. The self-moving equipment mentioned in the application can be various intelligent equipment with a cleaning function, for example, the self-moving equipment with a cleaning function comprises a self-moving equipment with a cleaning function, and the like. The mobile equipment is provided with sensors for following functions, such as a camera, a pulse radio (UWB) sensor and the like, and the sensors are matched with a proper algorithm to realize an effective and robust drawing establishing function.

The sensor includes various types, such as a vision sensor, a laser ranging sensor, an infrared sensor, a laser sensor, and the like, and the present embodiment is schematically described by taking the laser sensor as an example. A laser sensor is a radar system that collects information from the environment surrounding a mobile device by emitting a laser beam. The environmental data collected by the laser sensor comprises: distance, angle, etc. from objects surrounding the mobile device. The distance between the mobile device and the boundary of the area can be detected through the laser sensor, so that the position of the boundary point can be accurately positioned.

More specifically, the number of the sensors may be one or a plurality of sensors, and the sensors may be disposed on the top of the mobile device or disposed on the peripheral side of the mobile device, so that the distance between the boundary points located in each direction of the mobile device can be detected more quickly.

In addition, the use scene of the area identification performed by the mobile device in the application includes the ground of places such as families, shopping malls, schools and the like, and also can include the surfaces of various objects, such as flat plate surfaces and the like. The self-moving device of the application can be various, such as an air purification self-moving device, so as to realize air purification in an area.

In this application, the various shapes of the self-moving device are not limited, such as an oval, a circle, a convex polygon, etc., and the self-moving device may implement the method logic of controlling the travel of the self-moving device by installing software, APP, or writing a program in a corresponding device inside the self-moving device in a controller used with the self-moving device.

The embodiment of the application discloses a region identification method, as shown in fig. 1, comprising the following steps 101-104:

101. determining a region: and determining the area to be explored based on the boundary point of the detected environment.

In this embodiment, the boundary points are detected by the following method: controlling the self-moving equipment to scan the surrounding environment, and generating an environment map through a related mapping algorithm; and determining boundary points according to the environment map.

Specifically, the environment map may include at least one of a visual map and a grid map. The visual map is constructed in advance based on the environment image acquired by the visual sensor, and can describe the surrounding environment where the mobile device is located to a certain extent. The data acquired by the vision sensor comprises information of a tow bar environment image, including the pose of the mobile device corresponding to the environment image, feature points contained in the environment image, description words of the feature points and the like. A grid map is constructed based on environmental data collected by the laser sensors, the grid map being the product of digital rasterization of the environment from the area where the mobile device is located. Each grid in the grid map corresponds to a small area of the environment where the mobile device is located, each grid comprises information such as coordinates and whether the grid is occupied by an obstacle, and probability values of the occupied grids represent environment information of the corresponding area. The more grids in the grid map, the more detailed the grid map describes the environment in which the mobile device is located, and the higher the positioning accuracy.

In a specific use scene, the self-moving device is initially powered on and starts to work, the self-moving device scans the surrounding environment through the laser sensor to obtain an environment map of the surrounding environment, and then boundary points are determined based on the environment map.

The boundary points of the area to be searched are detected by a visual sensor provided in the mobile device. The area to be explored should be an area with a closed boundary, and the determination of the closed boundary includes the following two cases:

one is that the boundaries of the area to be explored are made up of boundary points detected by sensors, as shown in fig. 2. In this case, step 101 includes: and determining a real boundary based on the boundary points detected by the sensors, and determining a region to be explored based on the real boundary of the closed connection.

The other is that the boundaries of the area to be explored are not all real boundaries, and some of the boundaries are virtual boundaries determined by the detection range in which the sensor does not detect the boundary points, as shown in fig. 3, the solid line boundary is a real boundary, and the boundary with the diagonal line is a virtual boundary. In this case, step 101 includes: the method comprises the steps of determining a real boundary based on boundary points detected by the sensor, determining a virtual boundary based on a detection range in which the sensor does not detect the boundary points, and determining a region to be explored based on the real boundary and the virtual boundary which are connected in a closed mode.

The real boundary refers to a boundary formed by determined boundary points, since the boundary is a boundary that actually exists in an actual scene, such as a boundary of a wall, a boundary of an obstacle, and the like.

The virtual boundary refers to a boundary that does not actually exist but is determined by the detection range of the sensor, such as a boundary line with oblique lines in fig. 3.

In this embodiment, the sensor is preferably a laser sensor, and the signal range of the sensor can be set according to actual requirements, for example, set to be 1 meter, 3 meters, 5 meters, and the like.

From the area to be explored, determined in step 101, the travel range from the mobile device can be determined. In the subsequent steps, even if the area to be explored is not all areas where the self-moving device finally travels, the self-moving device finishes walking in the determined area to be explored, and then determines the next area to be explored, so that the regional exploration of the self-moving device is realized.

102. And (3) operation control: and selecting at least one working point in the area to be explored, and controlling the self-moving equipment to sequentially move to the at least one working point for operation.

This step 102 specifically includes: selecting a plurality of travel points uniformly distributed in the area to be explored as the working points, wherein the travel points comprise boundary points and/or area points.

The working points are uniformly distributed in the area to be explored, so that the whole area can be relatively uniformly covered when the mobile equipment works in the area to be explored, and the working effect is guaranteed. Taking the air purification self-moving equipment as an example, the air purification self-moving equipment is controlled to sequentially move to each working point, so that the air purification effect in the whole area can be ensured.

The number and the position of the travel points may be determined according to a predefined definition, for example, the arrangement density of the travel points in the area to be searched may be preset, and the number and the position of the travel points may be determined, or the number and the position of the travel points in the area to be searched may be determined according to the distance between the travel points.

After determining the plurality of travel points as the work points, self-planning a travel route from the mobile device to traverse the plurality of work points. The travel route may be various, such as a zigzag, etc., so as to sequentially travel to the respective work points in an optimal travel route.

It should be noted that the area to be searched includes both the area boundary and the area surrounded by the area boundary. The travel point may include only a region point located within the region to be explored, only a boundary point located on the boundary of the region, and a set of the region point and the boundary point.

In this embodiment, the self-moving device selects at least one working point in the area to be explored and controls the self-moving device to sequentially travel to each working point for operation, so that the operation requirement can be met without traversing all the points in the area to be explored from the self-moving device, and the control is convenient.

103. Detection control: and controlling the mobile equipment to continuously detect a new boundary point in the process of traveling to the working point and when traveling to the working point, and determining a next area to be explored based on the continuously detected new boundary point.

In this step, the self-moving device keeps the continuous detection of the laser sensor, so that the self-moving device continuously detects new boundary points in the process of traveling. Specifically, in the case where the laser sensor detects a boundary point, the boundary point is compared with the detected boundary point to determine whether the detected boundary point is a new boundary point.

In addition, when a new boundary point is detected in the process of traveling, the area to be explored is not immediately updated or the traveling route is not changed, but the traveling route of the self-moving equipment in the area to be explored is continuously maintained until the self-moving equipment finishes operating in the area to be explored. Specifically, the method further comprises: maintaining the traveling route of the self-moving equipment in the area to be explored so as to control the self-moving equipment to sequentially travel to each working point in the area to be explored.

And under the condition that the operation of the self-moving equipment in the area to be searched is finished, the self-moving equipment determines the next area to be searched based on the continuously detected new boundary points.

It should be noted that, for the next area to be explored, the current area to be explored should not be included. Therefore, the step 103 of determining the next area to be searched based on the new boundary points continuously detected includes the following steps S131 to S133:

s131, taking the area to be searched after the movement as a taboo area.

And S132, determining an updating area based on the new boundary point and the detected boundary point.

And S133, determining the next area to be explored based on the difference value between the updating area and the taboo area.

For the next area to be explored, it should also be an area with a closed boundary, and the determination of the closed boundary includes the following two cases:

one is that the boundaries of the area to be explored are made up of boundary points detected by sensors. In this case, determining an update region based on the new boundary point and the detected boundary point includes: determining a real boundary based on new boundary points detected by the sensor and detected boundary points, determining the update zone based on the real boundary of closed connections.

It can be seen that the determination of the real boundary is based not only on the new boundary points but also on the detected boundary points when determining the next area to be explored, so that the updated area enclosed by the determined real boundary includes the area to be explored which has already traveled since the mobile device.

The other is that the boundaries of the area to be explored are not all real boundaries, and a part of the area to be explored is a virtual boundary determined by the detection range of the boundary point which is not detected by the sensor. In this case, determining an update region based on the new boundary point and the detected boundary point includes: determining a real boundary based on the new boundary points detected by the sensor and the detected boundary points; determining a virtual boundary based on a detection range in which the sensor does not detect the boundary point; an update region is determined based on the real and virtual boundaries of the closed connection.

See fig. 3 and 4. Fig. 3 shows the determination of the first time to-be-searched region R21 from the mobile device, and fig. 4 shows the determination of the second time to-be-searched region R22 from the mobile device.

In fig. 3, the real boundary is determined to be E11 based on the boundary points detected by the sensors, the virtual boundary is determined to be E12 based on the detection range in which the boundary points are not detected by the sensors, and the region to be explored is determined to be R21 by the real boundary E11 and the virtual boundary E12.

In fig. 4, the real boundary is determined to be E13 based on the new boundary points detected by the sensors, and the virtual boundary is determined to be E14 based on the detection ranges of the detected boundary points by the sensors. And determining that the updated region is R1 through the real boundaries E11 and E13 and the virtual boundary E14, and determining that the region to be searched for the second time is a region R22 obtained by subtracting the region to be searched for R21 from the updated region R1.

104. And executing operation control and detection control in the next area to be explored until the boundary point is detected.

Specifically, in this embodiment, after the boundary point is detected, no new boundary point is detected during the process of the mobile device performing the operation control and the detection control in the next area to be searched.

The second embodiment of the present application discloses a region identification method, as shown in fig. 5, including steps 501-507:

501. determining a region: and determining the area to be explored based on the boundary point of the detected environment.

In this embodiment, the mobile device is initially powered on and starts to operate, the mobile device scans the surrounding environment through the laser sensor to obtain an environment map of the surrounding environment, and then the boundary point is determined based on the environment map.

The boundary points of the area to be searched are detected by a visual sensor provided in the mobile device. The area to be explored includes the following two cases:

one is that the boundaries of the area to be explored are made up of boundary points detected by sensors, as shown in fig. 2. In this case, step 501 includes: and determining a real boundary based on the boundary points detected by the sensors, and determining a region to be explored based on the real boundary of the closed connection.

The other is that the boundaries of the area to be explored are not all real boundaries, and a part of the area to be explored is a virtual boundary determined by the detection range of the boundary point which is not detected by the sensor, as shown in fig. 3. In this case, step 501 includes: the method comprises the steps of determining a real boundary based on boundary points detected by the sensor, determining a virtual boundary based on a detection range in which the sensor does not detect the boundary points, and determining a region to be explored based on the real boundary and the virtual boundary which are connected in a closed mode.

502. Selecting a plurality of travel points uniformly distributed in the area to be explored as the working points, wherein the travel points comprise boundary points and/or area points.

It should be noted that the area to be searched includes both the area boundary and the area surrounded by the area boundary. In this embodiment, the area point is a traveling point located in the area to be explored, and the boundary point is a traveling point located on the boundary of the area.

For the selection of the operating point, the above embodiments have been described in detail, and are not repeated herein.

In the step, the working points are uniformly distributed in the area to be explored, so that the whole area can be relatively uniformly covered when the mobile equipment works in the area to be explored, and the working effect is ensured. Taking the air purification self-moving equipment as an example, the air purification self-moving equipment is controlled to sequentially move to each working point, so that the air purification effect in the whole area can be ensured.

503. And controlling the self-moving equipment to sequentially move to a plurality of working points for operation.

504. And controlling the mobile equipment to continue detecting and judging whether a new boundary point is detected or not in the process of moving to the working point and when the mobile equipment moves to the working point, if so, executing step 505, and if not, executing step 507.

505. Maintaining the traveling route of the self-moving equipment in the area to be explored so as to control the self-moving equipment to sequentially travel to each working point in the area to be explored.

506. A next area to be explored is determined based on the new boundary points which are continuously detected, and the next area to be explored is taken as the current area to be explored, and the step 502 is executed.

Specifically, step 506 includes: and taking the advanced to-be-searched area as a tabu area, determining an updating area based on the new boundary point and the detected boundary point, and determining the next to-be-searched area based on the difference value between the updating area and the tabu area.

For the next area to be explored, the following two cases are included:

It can be seen that the determination of the real boundary is based not only on the new boundary points but also on the detected boundary points when determining the next area to be explored, so that the updated area enclosed by the determined real boundary includes the area to be explored which has already traveled since the mobile device. After the update area is determined, the taboo area is subtracted from the update area, so that the next area to be searched can be obtained.

507. And finishing the job task from the mobile equipment.

For example, after the mobile device is powered on, boundary points Q1-Q100 in the detected environment are determined, and the region to be explored R11 is determined based on the boundary points Q1-Q100. Then, a plurality of travel points P1 to P10, which are all distributed in the region to be searched R11, are selected as operating points. During the control of the travel of the self-moving apparatus in the to-be-explored zone R11, the self-moving apparatus determines that new unidentified boundary points Q101-Q200 are detected. Then, the self-moving device does not immediately update the area to be explored or change the travel route according to the new boundary point, but after the area to be explored R11 is finished, the self-moving device determines the next area to be explored R12 according to the boundary points Q101-Q200 and the area to be explored which is finished, and then continues to control the self-moving device to travel in the area to be explored R12.

Through the steps 501-507, the self-moving equipment can advance in different areas, and only the working point in the current area range to be explored is concerned in each advancing, so that the advancing track of the self-moving equipment is more regular, and the area boundary is more efficiently identified.

Optionally, in practical applications, there may be some abnormal working points, which cannot be reached by the self-moving device, for example, when the self-moving device suddenly encounters an obstacle or a door opened by a person during walking in a room. To overcome this, the method further comprises:

and S508, under the condition that the mobile equipment is controlled to move to the working point, recording the abnormal working point, and continuously controlling the mobile equipment to move to other working points.

And S509, under the condition that the mobile equipment finishes moving to other working points, continuing to plan a moving route according to the abnormal working points so as to control the mobile equipment to sequentially move to the abnormal working points.

In the area identification method of the embodiment, an area to be explored is determined based on boundary points, at least one working point is selected in the area to be explored, and the mobile device is controlled to sequentially move to the working point for operation; and under the condition that new boundary points are continuously detected in the operation process, the self-moving equipment is not controlled to change the traveling route, but after the current area to be searched is completely traveled, the next area to be searched is determined according to the new boundary points, and the self-moving equipment is controlled to execute operation control and detection control in the next area to be searched until all the boundary points are completely detected, so that the sub-area traveling of the self-moving equipment is realized, the traveling track of the self-moving equipment is more regular, and the area boundary is more efficiently identified.

Specific example 1

In one embodiment, the application environment is a home scene, the self-moving device is an air purification self-moving device, and the area to be explored is a room, and correspondingly, the area identification method comprises the following steps a 1-a 8:

a1, determining a boundary E01 based on the boundary points Q001-Q100 of the detected environment, and determining a region to be searched R01 based on the boundary E01.

In this example, the boundary E01 is a true boundary.

a2, selecting working points P01-P10 in the area to be searched, and controlling the self-moving equipment to sequentially move to the working points P01-P10 for operation.

a3, controlling the self-moving equipment to continuously detect new boundary points in the process of traveling to the working points P01-P10 and traveling to the working points P01-P10.

a4, recording the operating point P5 when the control of the mobile equipment to the operating point P5 is abnormal, and continuing to control the mobile equipment to the operating points P6-P10.

a5, after controlling the mobile device to travel to the working point P10, continuing to plan the travel route from the mobile device to the working point P5.

a6, if there is still an abnormality in the control from the mobile device to the operating point P5, the control is cancelled and the control continues to the operating point P5, and step a7 is executed.

a7, if the control is normal from the mobile equipment to the working point P5, the step a7 is executed after the control is finished from the mobile equipment to the working point P5.

a8, determining that the task is completed since the mobile device does not detect a new boundary point.

The area to be explored R0 may be a room corresponding to the application environment, and the opening area of R0 should be the door of the room. In the case where the opening area is detected by the sensor of the self-moving device, since the boundary point is not detected within the detection range of the sensor, the virtual boundary E2 is determined with the detection range of the sensor.
