Technical Field
[0001] The utility model relates to an array camera, in particular to a cooling device for an array camera. Background Technique
[0002] The problems faced by traditional camera monitoring products are insurmountable problems inherent in optics. In essence, the focal length of an optical lens is inversely proportional to the field of view angle, resulting in "the larger the focal length, the narrower the viewing angle". Only by increasing a large number of "probes" can this be addressed, which brings many application confusions. Currently, through array computing vision technology, a comprehensive integrated solution for multi-lens multi-channel synchronous acquisition, unified image processing, mapping transformation, full stitching fusion, and depth detection is provided. In recent years, the third-generation imaging technology (computational imaging) in the form of "array camera + image processor (GPU) + image algorithm" is emerging in embryonic form and has begun to be applied in practice with the concept of "small-area panoramic view". It realizes seamless coverage of the entire area, saves the number of probe installations, and improves the usability and effectiveness of the monitoring system.
