Embodiment Construction
[0019] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:
[0020] refer to figure 1 , figure 2 , the steps of the method for detecting the pose of a micro-column cavity target using a target alignment sensor in this embodiment are as follows:
[0021] (1) Object distance adjustment
[0022] A target alignment sensor composed of three orthogonally arranged CCD image sensors A, B, and C is used, and the intersection of the optical axes of the three CCD image sensors A, B, and C is used as the reference point for the detection of the target alignment sensor. , the micro-column cavity target is placed on the reference point detected by the target alignment sensor, and the object distances of the three CCD image sensors A, B, and C are respectively adjusted until the upper and lower end faces of the micro-column target and the upper and lower edges of the side are imaged clear;
[0023] (2) Feature point extractio...
