It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
To facilitate understanding of the present embodiment, first, a navigation method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the navigation method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: terminal device or server or other processing equipment, terminal device can be AR equipment, can include for example that AR glasses, panel computer, smart mobile phone, intelligence wearable device etc. have obvious display function and data processing function's equipment, and AR equipment can pass through application connection cloud end server.
Referring to fig. 1, a flowchart of a navigation method provided in an embodiment of the present disclosure is shown, where the method includes steps 101 to 104, where:
And 102, acquiring a navigation path of the AR equipment based on the three-dimensional pose information of the AR equipment and the destination information of the AR equipment.
And 103, determining the display posture of the three-dimensional virtual arrow based on the three-dimensional pose information of the AR equipment and the navigation path.
And 104, displaying an AR navigation chart containing the three-dimensional virtual arrow and the live-action image on the AR equipment according to the display posture of the three-dimensional virtual arrow.
The following is a detailed description of the above steps 101 to 104.
For step 101,
The acquiring of the live-action image shot by the AR device may be acquiring of a live-action image in a target scene where the AR device is located, shot by the AR device in real time. When the AR device shoots the live-action image, the AR device can be obtained by calling an image acquisition device of the AR device to shoot in real time after detecting that the AR device starts the navigation application.
In a possible implementation manner, the determining of the three-dimensional pose information of the AR device may be determined by the AR device itself based on a live-action image captured by the AR device, or may be determined by the cloud server based on the live-action image by transmitting the live-action image to the cloud server by the AR device, and then the AR device acquires the determined three-dimensional pose information from the cloud server.
The method for determining the three-dimensional pose information by the AR device may be the same as the method for determining the three-dimensional pose information by the cloud server, and the method for determining the three-dimensional pose information will be described below by taking the AR device as an execution subject for determining the three-dimensional pose information as an example.
The three-dimensional pose information of the AR device may be pose information of the AR device in a three-dimensional coordinate system in the target scene, and the three-dimensional pose information may include position information and orientation.
In a possible implementation manner, when determining the three-dimensional pose information of the AR device, position information of a plurality of target detection points in a target scene corresponding to a live-action image may be detected, a target pixel point corresponding to each target detection point in the live-action image may be determined, then depth information (for example, obtained by performing depth detection on the live-action image) corresponding to each target pixel point in the live-action image may be determined, and then the three-dimensional pose information of the AR device may be determined based on the depth information of the target pixel points.
The target detection point may be a preset position point in a scene where the AR device is located, for example, a cup, a fan, a water dispenser, and the like, and the depth information of the target pixel point may be used to represent a distance between the target detection point corresponding to the target pixel point and an image acquisition device of the AR device. The position coordinates of the target detection points in the scene coordinate system are preset and fixed.
Specifically, when the three-dimensional pose information of the AR equipment is determined, the orientation of a target pixel point corresponding to a target detection point in the scene image can be determined according to the coordinate information of the target pixel point in the scene image; and determining the position information of the AR equipment based on the depth value of the target pixel point corresponding to the target detection point, so that the three-dimensional pose information of the AR equipment can be determined.
In another possible implementation manner, when the three-dimensional pose information of the AR device is determined, a live-action image shot by the AR device may be matched with a three-dimensional model corresponding to a target scene where the AR device is located, and the three-dimensional pose information of the AR device may be determined based on a matching result.
Specifically, when a three-dimensional model corresponding to a target scene is constructed, the three-dimensional model can be constructed based on a panoramic video, and based on the panoramic real scene, area images corresponding to all position areas of the three-dimensional model and corresponding pose information when the area images are shot can be obtained; when the live-action image shot by the AR device is matched with the three-dimensional model, the live-action image shot by the AR device can be matched with the area images corresponding to all position areas of the three-dimensional model, the target area image which is successfully matched and the relative position relationship between the shooting positions of the target area image and the live-action image are determined, and the three-dimensional position information of the AR device when the live-action image is shot can be determined based on the relative position relationship and the position information when the target area image is shot.
In another possible implementation, the three-dimensional pose information of the AR device may be determined by means of an inertial measurement unit IMU inside the AR device. Specifically, data acquired by the inertial measurement unit IMU may be acquired, and then the three-dimensional pose information of the AR device may be determined based on the data acquired by the inertial measurement unit IMU.
Because the three-dimensional pose of the AR equipment is changed in real time, the three-dimensional pose information of the AR equipment is determined based on the data collected by the inertial measurement unit, the three-dimensional pose information of the AR equipment can be updated in real time, and the display posture of the three-dimensional virtual arrow can be further adjusted in real time.
However, in practical applications, data acquired by an Inertial Measurement Unit (IMU) may have errors, and therefore, in order to avoid an influence of a Measurement error of the IMU on three-dimensional pose information of the AR device, the three-dimensional pose information of the AR device may be calibrated based on live-action images captured by the AR device at intervals of a preset time.
Specifically, the three-dimensional pose information of the AR device may be determined based on a live-action image captured by the AR device every preset time period, and then the three-dimensional pose information determined based on the live-action image may be compared with the three-dimensional pose information determined based on the data acquired by the inertial measurement unit IMU, and if not, the three-dimensional pose information determined based on the live-action image may be updated based on the three-dimensional pose information determined based on the data acquired by the inertial measurement unit IMU, that is, the three-dimensional pose information determined based on the live-action image may be used as the current three-dimensional pose information of the AR device.
In another possible implementation manner, when the three-dimensional pose information of the AR device is initially determined, the determination may be performed based on a live-action image captured by the AR device, then, in the process of displaying the AR navigation map, the three-dimensional pose information of the AR device may be determined in real time based on an inertial measurement unit IMU built in the AR device, the three-dimensional pose information of the AR device is re-determined at intervals of a preset time based on the live-action image captured by the AR device, and the three-dimensional pose information of the AR device determined by the inertial measurement unit IMU is updated based on the re-determined three-dimensional pose information of the AR device.
Here, because the measurement accuracy error of the inertial measurement unit is large, the three-dimensional pose of the AR device is calibrated based on the live-action image shot by the AR device, so that the influence of the error caused by the measurement accuracy of the inertial measurement unit can be avoided, and the display accuracy of the three-dimensional virtual arrow display pose is further improved.
With respect to step 102,
In one possible implementation, the destination information of the AR device may be input by the user based on the AR device, and when the navigation path of the AR device is acquired based on the three-dimensional pose information of the AR device and the destination information of the AR device, the user may input the destination information based on the AR device, and then the AR device sends the three-dimensional pose information of the AR device and the destination information of the AR device to the server, and the server determines a navigation path to a target location corresponding to the destination information and sends the navigation path to the AR device, where the navigation path may include the current location of the AR device.
For step 103,
In a possible implementation manner, when the display posture of the three-dimensional virtual arrow is determined based on the three-dimensional pose information and the navigation path of the AR device, a target inflection point closest to the AR device in the navigation path may be determined, and then the display posture of the three-dimensional virtual arrow may be determined based on the three-dimensional pose information and the position information of the target inflection point of the AR device.
Specifically, the navigation path includes an inflection point and an execution segment, and the inflection point may be a position point where the turning angle exceeds a preset angle, for example, a position point where the turning angle exceeds 30 ° may be determined as the inflection point.
It should be noted that the three-dimensional pose information of the AR device includes position information and orientation information of the AR device, and the three-dimensional virtual arrow has six degrees of freedom, for example, if the AR device is a mobile phone, the three-dimensional virtual arrow shown in the AR device may be as shown in fig. 2.
When the display posture of the three-dimensional virtual arrow is determined based on the three-dimensional pose information of the AR device and the position information of the target inflection point, the state variation corresponding to each degree of freedom of the three-dimensional virtual arrow may be determined based on the three-dimensional pose information of the AR device and the position information of the target inflection point, and then the display posture of the three-dimensional virtual arrow may be determined based on the state variation of the three-dimensional virtual arrow in each degree of freedom.
The state variation of the three-dimensional virtual arrow in each degree of freedom respectively represents the movement amount along the x axis, the y axis and the z axis and the rotation amount around the x axis, the y axis and the z axis, and based on the state variation of the three-dimensional virtual arrow in each degree of freedom, the display posture of the three-dimensional virtual arrow pointing to the target inflection point can be determined.
Here, when the three-dimensional virtual arrow is presented based on the determined presentation posture, the three-dimensional virtual arrow always points to the position information corresponding to the target inflection point, and the position information of the target inflection point may be three-dimensional coordinate information whose z-axis area is consistent with the height of the AR device and may vary with the change in the height of the AR device.
In practical application, when the AR device is close to the target inflection point, the display posture of the three-dimensional virtual arrow needs to be adjusted in advance to prompt the user to turn in the direction of the target inflection point.
Specifically, each inflection point in the navigation path corresponds to a turning region, and the turning region corresponding to the current inflection point is a region which is in a straight line from the previous inflection point to the current inflection point and is a preset distance away from the current inflection point.
For example, if the navigation path is as shown in fig. 3, the navigation path includes an inflection point 1, an inflection point 2, an inflection point 3, and an inflection point 4, and the inflection region corresponding to each inflection point is a gray region nearest to the inflection point.
In practical application, the size of the turning area corresponding to each turning point can be the same, or can be adjusted according to the size of the turning angle of the target turning point, for example, if the turning angle corresponding to the target turning point is smaller than a first preset angle, it is indicated that the turning angle corresponding to the target turning point is smaller, so that a user does not need to turn in advance too early, and the size of the area corresponding to the turning area can be a first preset size; if the turning angle corresponding to the target turning point is greater than or equal to a first preset angle and smaller than a second preset angle, the area size of the turning area of the target turning point can be a second preset size; if the target inflection point is greater than or equal to the second preset angle, the size of the region of the turning region of the target inflection point may be a third preset size, the first preset size is smaller than the second preset size and the third preset size, and the second preset size is smaller than the third preset size.
In one possible implementation, when it is detected that the AR device is located in a turning region of the target turning point, when determining the display pose of the three-dimensional virtual arrow, a next turning point corresponding to the target turning point and position information of the next turning point may be determined based on the position information of the target turning point, and then the display pose of the three-dimensional virtual arrow may be determined based on the pose information of the AR device and the position information of the next turning point.
Here, the next inflection point corresponding to the target inflection point may be an inflection point closest to the target inflection point in an area not reached by the AR device in the navigation path.
When the display posture of the three-dimensional virtual arrow is determined based on the posture information of the AR device and the position information of the next inflection point, the state variation corresponding to each degree of freedom of the three-dimensional virtual arrow may be determined based on the three-dimensional posture information of the AR device and the position information of the next inflection point, and then the display posture of the three-dimensional virtual arrow may be determined based on the state variation corresponding to each degree of freedom of the three-dimensional virtual arrow.
