Title:
BLIND SPOT-FREE MULTI-VIEW PANORAMIC THREE-DIMENSIONAL IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/103500
Kind Code:
A1
Abstract:
A blind spot-free multi-view panoramic three-dimensional imaging device, which relates to the technical field of panoramic imaging. The device comprises a front lens group (18) or a planar reflector (21), an aspheric reflector (5), a middle lens group (6), a panoramic block (3), a rear lens group (4) and an image plane (7) which are longitudinally arranged along an optical axis. The aspheric reflector (5) comprises a central hole (19) and an annular reflection surface (8). The panoramic block (3) comprises a front central circular transmission surface (13), a front reflection surface (11), a front transmission surface (9), a rear reflection surface (10) and a rear transmission surface (12). The front transmission surface (9) and the rear reflection surface (10) are annular. The inner edge of the front reflection surface (11) is connected to the edge of a front central circular transmission surface (13). The edge of the front transmission surface (9) is respectively connected to the outer edge of the front reflection surface (11) and the outer edge of the rear reflection surface (10). The inner edge of the rear reflection surface (10) is connected to the edge of the rear transmission surface (12). The radius of curvature of the front central circular transmission surface (13) is the same as that of the front reflection surface (11), and is different from that of the front transmission surface (9) is different. The radius of curvature of the rear reflection surface (10) is the same as that of the rear transmission surface (12). The blind spot-free multi-view panoramic three-dimensional imaging device can realize blind spot-free multi-view panoramic three-dimensional imaging.
