Embodiment Construction
[0130] The present invention will be further described below in conjunction with the accompanying drawings.
[0131] With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, the omnidirectional computer vision sensor system shown in Fig. Focus 4 Refraction. The real image 7 is reflected by the hyperboloid mirror into the condenser lens for imaging, and a flame point P1 (x*1, y*1) on the imaging plane corresponds to the coordinate A (x1, y1) of a point of the flame in space , z1).
[0132] In Figure 1, 1-hyperbolic mirror, 2-incident light, 3-focus Om(0,0,c) of hyperbolic mirror, 4-virtual focus of hyperbolic mirror is camera center Oc(0,0,-c ), 5-reflected light, 6-imaging plane, 7-space coordinates A(x1, y1, z1) of the real image, 8-space coordinates of the image incident on the hyperboloid mirror surface, 9-reflection on the imaging plane Point P1(x*1, y*1).
[0133] The optical system formed by the hyperbolic mirror shown in Fig. 1 can be represented by the fol...
