The first coordinate conversion relation is used for converting the pixel coordinates of the first object set in the pixel coordinate system of the first image into world coordinates under a preset world coordinate system, and the second coordinate conversion relation is used for converting the pixel coordinates of the second object set in the pixel coordinate system of the second image into world coordinates under the preset world coordinate system, so that the first object set in the first image and the second object set in the second image are converted into the same coordinate system.
In this embodiment, by acquiring the object sets at two positions in the target device, the problem that the detection is inaccurate due to the fact that the occlusion condition is easy to occur when the object sets are acquired at a single position is avoided, that is, the first image and the second image are acquired by the acquisition device, wherein the first image includes the first object set acquired at the first position in the target device, and the second image includes the second object set acquired at the second position in the target device, and because the first object set and the second object set are the object sets acquired at two positions in the same target device, the first object set and the second object set may have a situation of partially repeating or completely repeating.
In one implementation of the embodiment of the present application, a first camera is disposed at a first location within the target device for acquiring a first image including a first set of objects at the first location, and a second camera is disposed at a second location within the target device for acquiring a second image including a second set of objects at the second location.

In the embodiment of the application, a world coordinate system is preset in target equipment, in order to unify the objects in a first object set and a second object set into the world coordinate system, for each first coordinate in the first coordinate set and a first coordinate conversion relation, the first coordinate is converted into a first target coordinate under the world coordinate system, so as to obtain a first target coordinate corresponding to each first object under the preset world coordinate system, namely, a first target coordinate set is obtained, and similarly, a second target coordinate set of the second object set in the preset world coordinate system is determined based on the second coordinate set and the second coordinate conversion relation.
S104, determining object information of an object in the target equipment based on the first target coordinate set and the second target coordinate set.
In the embodiment of the application, the object information refers to attribute information of the object in the target device. Because the target coordinates in the first target coordinate set and the second target coordinate set are the coordinates in the preset world coordinate system, and the world coordinate system is preset based on the target device, the object information of the object in the target device can be determined based on the first target coordinate set and the second target coordinate set.
In the embodiment of the application, the first target coordinate set corresponding to the first object set and the second target coordinate set corresponding to the second object set can be determined through the first image comprising the first object set and the second image comprising the second object set acquired in the target equipment, so that the object information of the object in the target equipment is determined, and the object information of the object in the equipment is automatically determined without manual operation; in addition, the object set is acquired at two positions in the target equipment, so that the problem of inaccurate detection caused by the shielding condition easily occurring when the object set is acquired at a single position can be avoided, and the acquired object set is ensured to be more comprehensive and accurate.
In yet another embodiment of the present application, the first image and the second image may be acquired by:
Determining attribute information of the first object based on the first image for any first object in the first object set, and determining attribute information of the second object based on the second image for any second object in the second object set;
and determining the first object and the second object with the same attribute information as the same object in the target equipment.
In the embodiment of the application, the attribute information can include, but is not limited to, information including color, shape, texture, text, and the like. When the attribute information of a first object and a second object are identical, determining that the first object and the second object are the same object in the target device. According to the scheme, whether the first object and the second object are the same object or not can be directly determined according to the first image and the second image, and the determination process is simple and efficient.
In still another embodiment of the present application, the first coordinate conversion relationship and the second coordinate conversion relationship may be determined by:
Step one, obtaining world coordinates of six calibration points preset in the target equipment under the preset world coordinate system;
Step two, for each calibration point, determining a first pixel coordinate of a first coordinate system to which the calibration point belongs in the first image, and determining a second pixel coordinate of a second coordinate system to which the calibration point belongs in the second image, wherein the first image and the second image both contain six calibration points;
And step three, determining the first coordinate conversion relation based on world coordinates of the six calibration points and the first pixel coordinates, and determining the second coordinate conversion relation based on world coordinates of the six calibration points and the second pixel coordinates.
In the embodiment of the present application, six calibration points are set in the target device in advance, as shown in fig. 3, where each corner point of the black-white grid may be used as a calibration point, and six calibration points may be selected. A world coordinate system is established in target equipment in advance, wherein one establishment mode is as follows: and establishing a world coordinate system by taking the midpoint of the connecting line of the first camera and the second camera as a coordinate origin, such as an O-XYZ coordinate system shown in fig. 4. The method for determining the first coordinate conversion relation and the second coordinate conversion relation is the same, and specifically comprises the following steps:
For a point q= (X Y Z) T in the world coordinate system, if the corresponding point (pixel coordinate system) in the image captured by the camera is q= (u v) T, there is:
the conversion to homogeneous coordinates is as follows:
The above-mentioned formula is developed:
the finishing method can obtain:
Therefore, since the above formula can be generated by each group of world coordinates and pixel coordinates, the matrix P can be solved by knowing the world coordinates and pixel coordinates of the six calibration points, thereby obtaining the conversion relationship between the pixel coordinate system and the world coordinate system. In order to prevent the conversion relation from being invalid due to unexpected movement of the cameras, the two cameras need to calibrate and correct the conversion relation at regular time.
In still another embodiment of the present application, the object information includes the number of objects in the target device, as shown in fig. 5, and the step S104 may include the steps of:
S201, determining a coordinate combination set based on the first target coordinate set and the second target coordinate set, wherein the coordinate combination set comprises at least one coordinate combination, and the coordinate combination comprises one first target coordinate in the first target coordinate set and one second target coordinate in the second target coordinate set.

In the embodiment of the application, the preset distance threshold is obtained by experimental verification according to specific parameters of the camera, the environment in the target equipment and the like. When the distance corresponding to the coordinate combination is smaller than the preset distance threshold, the first object corresponding to the first target coordinate and the second object corresponding to the second target coordinate in the coordinate combination are the same object in the target device. Therefore, a coordinate combination with a distance smaller than a preset distance threshold value is selected from the coordinate combination set as a target coordinate combination, and by determining the third number of the target coordinate combinations, it can be known how many of the first object and the second object are repeated.
S204, determining a first number of first objects corresponding to the first object set, and determining a second number of second objects corresponding to the second object set.

For example, the first image includes 1, 2, 3, 4, and 5 first objects, the second image includes 3, 4, 5, and 6 second objects, and the target combination is determined to be three, so that the number of objects in the target device can be determined to be 5+4-3=6, that is, 1, 2, 3, 4, 5, and 6 six objects in the target device are determined.
In the embodiment of the application, any first target coordinate in the first target coordinate set and any second target coordinate in the second target coordinate set can be combined to obtain the coordinate combination set, and whether the first object corresponding to the first target coordinate and the second object corresponding to the second target coordinate in the coordinate combination are the same object in the target equipment or not is determined by determining the distance corresponding to the coordinate combination, so that the number of the objects in the target equipment is determined, the number of the objects in the equipment is automatically determined, artificial participation is not needed, and the determination efficiency is improved.
In yet another embodiment of the present application, the method may further comprise the steps of:
