Embodiment Construction
[0046] The present invention is further described below in conjunction with the accompanying drawings, but the scope of the present invention is not limited in any way.
[0047] 1. Operation process of planar target detection
[0048] like figure 1 As shown, the framework of the present invention can be divided into two parts: model building and target detection. In the model building stage, the contour model of the target is obtained by rasterizing the design drawing or performing continuous edge extraction on the template target. The target detection part uses the contour model of the target Candidate targets are extracted, and the precise location of the target is obtained through target screening and precise positioning algorithms.
[0049] 2. The specific implementation process of plane target detection
[0050] The method for detecting plane objects based on continuous edge features provided by the present invention can be summarized as follows:
