Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0044] see figure 1 , is a schematic diagram of wearing and using the omnidirectional camera scene recording device of the present invention, wherein 1 is a 180-degree omnidirectional camera device based on a ring lens; 2 is the host of the omnidirectional camera scene recorder device; 3 is the high-speed video data connected to 1 and 2 Wire. In the present invention, the omnidirectional camera scene recording device includes two parts: a host and an extension: the extension is an omnidirectional camera, and when law enforcement personnel use it in practice, they can usually be fixed on the top of the big hat or on the left and right chests with movable clips; It can be fixed on the outer belt of the police uniform or placed in the jacket pocket. A high-speed video data cable is used to connect the host and extension.
[0045] see figure 2 , the annular ...

The invention discloses a high-definition on-site law enforcement recording device with an annular lens. The device can provide omnidirectional shooting for on-site law enforcement. The device comprises a host machine and an extension. The extension is an omnidirectional imaging device for omnidirectional shooting of a scene, the annular lens is used for replacing a traditional lens, and annular omnidirectional images are formed on an imaging plane. The host machine is used for collection control, correction processing, compression, storage, playing control and the like of omnidirectional videos, mainly composed of an embedded processing board, a liquid crystal display screen, a function key control panel and an outer shell, and converts the omnidirectional images to cylindrical projection images which human eyes are accustomed to. The host machine and the extension are connected through a high-speed data line. The design aims at providing the high-definition on-site law enforcement recording device which is exquisite in design, convenient to use and capable of shooting the whole scene in an omnidirectional mode.
Description
Technical field: [0001] The invention relates to the field of digital video camera and optical design, in particular to a high-definition on-site law enforcement recording device with a ring lens. Background technique: [0002] The video surround lens is an ultra-wide-angle lens similar to a fisheye lens, which can provide an imaging effect of 180° or even a larger field of view. With the advantages of omnidirectional viewing angles and the ability to cover a wide range of scenes, it is used in panoramic video surveillance and robot visual navigation. , virtual reality space construction and other fields have been more and more widely researched and applied. [0003] For various law enforcement departments such as traffic police, urban management, taxation, and industry and commerce, how to obtain evidence on the spot in a timely and effective manner is a difficult problem at present. The inability to obtain evidence on the spot in a timely and effective manner has resulted ...
