Abstract

The invention discloses video acquisition equipment. The video acquisition equipment comprises a processor, a digital selector and more than two digital video acquirers; the processor is used for controlling and receiving video data forwarded by the digital selector; the digital video acquirers are used for acquiring the video data, and sending the video data to the digital selector; furthermore, video areas acquired by the adjacent digital video acquirers have an overlapped part; the digital selector is used for gating the video data, and forwarding the video data to the processor; and the processor is used for receiving the video data, and splicing various video data corresponding to the overlapped part to form video output data. On the premise that the wide imaging view is satisfied and distortion does not exist, the video acquisition equipment disclosed by the invention has low requirements on a processor interface; and thus, the integration level of the video acquisition equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of video capture, and more specifically, to a video capture device and method. Background technique [0002] Miniature analog cameras or digital video capture devices are widely used in video capture devices due to their good imaging effects, small size, and easy installation. However, the angle of view of these cameras without lens distortion is generally between 45 and 90 degrees. The imaging field of view is 165-180 degrees, and a wide-angle lens with a wider imaging field of view can be used. [0003] However, because the wide-angle lens itself is a convex mirror, it often produces a distorted perspective relationship, forming serious distortion, which reduces the recognition and reliability of the image or video displayed by the video capture device based on the wide-angle lens. It is beneficial to structural design and installation, and reduces the integration degree of the system. [0004] I...
