[0044] The present invention will be further described below in conjunction with accompanying drawing.
[0045] According to the pixel coordinate information, the evaluation index calculation in the camera image plane can be completed, including the accuracy rate of sphere matching and the average error rate of sphere matching. The evaluation process includes the following steps:
[0046] Step 1: metal ball and scene layout;
[0047] a. Scene layout: Scatter and arrange several metal balls in the field of view of the camera and radar. The metal balls keep a certain distance from each other, satisfying that the pixel boundaries of each calibration ball can be separated in the image coordinate system, and the point cloud boundaries can be separated in the three-dimensional coordinate system;
[0048] figure 1 It is a scene layout diagram, in which 101 is a metal ball, and 102 is a monocular camera and a millimeter-wave radar system;
[0049] b. Data collection: After the rada...
