step 110: and respectively projecting the parts to be detected along the coordinate axis plane, and screening the projection view with the largest projection area to obtain the target projection view.
Each part to be detected needs to be designed with a locating surface, and the locating surface comprises a plurality of locating points. The part to be detected can be a part of the object to be detected, for example, the body of a motor vehicle, and the locating surface is often required to be parallel to the whole part, so that whether the locating point and the locating surface meet the requirements can be judged through the detection of the locating point. The target projection view is one of the projection views, and a specific projection view can be referred to as a schematic diagram shown in fig. 2.
Referring to fig. 2, fig. 2 is a schematic diagram of a part to be inspected projected along a coordinate axis plane, where the projection view shown in fig. 2 includes:

If the distance from the positioning point to the long side 2 (length l=y2) in fig. 3 is z2, and z2 is smaller than the distance from the positioning point to the other long side 1 (length l=y1), the positioning point is distributed on one side of the long side 2 and belongs to the second long side distribution, and all the positioning points distributed on one side of the long side 2 can be counted by analogy. When the distribution of the positioning points on one side of the long side 2 is calculated to be reasonable, the distance between adjacent positioning points can be compared with the dimension of the long side where the adjacent positioning points are located. By comparing the distances from the positioning point to two long sides or the broadsides, the positioning point is distributed on which long side is determined, and the same is true for the distribution situation of the positioning point on the broadsides, wherein the length from the positioning point to the broadside 1 (length l=z1) is y2, and y2 is smaller than the distance from the positioning point to the other broadside 2 (length l=z2), so that the positioning point is distributed on one side of the broadside 1 and belongs to the first broadside distribution.
Step 140: according to the distribution condition, two adjacent positioning points are arbitrarily selected for detection.
In some embodiments of the present application, according to the distribution situation, two adjacent positioning points are arbitrarily selected for detection, including: selecting any two adjacent positioning points in one long-side distribution or one wide-side distribution in the distribution condition; and comparing the distance between two adjacent positioning points with the length or the width of the target projection view to obtain the detection result of the two adjacent positioning points.
In the process, the projection coordinates of the positioning points on the coordinate plane are compared with the length or width of the whole projection of the part, and whether the selected positioning points meet the requirements can be accurately judged according to the comparison result.

In the process, the application can accurately judge whether the selected positioning point meets the requirement or not through comparing the preset threshold value with the positioning point and the projection length or width ratio.
The preset threshold value can be set according to requirements, for example, 2/3, and the positioning point detection result report includes coordinates of two adjacent positioning points and a result of whether each positioning point meets the requirements or not.
Specifically, reference may be made to a schematic diagram of the anchor point determination method shown in fig. 4.
