Omnidirectional camera shooting field recorder based on catadioptric type optical structure

Abstract

The invention discloses an omnidirectional camera shooting field recorder based on a catadioptric type optical structure. The omnidirectional camera shooting field recorder comprises a main machine and a extension machine, wherein the extension machine is an omnidirectional imaging device to conduct all-round shooting to field and uses a catadioptric omnidirectional imaging method based on two reflections of an upper reflection mirror and a lower reflection mirror, and light emitted by an object in a space scene is reflected by a curved mirror on the upper portion, is reflected again by a reflection mirror on the lower portion, enters an imaging lens and forms a looped omnidirectional image. The main machine has the functions of collecting control, correction treatment, compression, storage, playing control and the like of an omindirectional video. The main machine and the extension machine are connected through a high-speed data line. The omnidirectional camera shooting field recorder is simple in structure and convenient to use, can be held in hands or worn on positions of shoulder marks, peaked caps and the like, and can be assembled on the outer top portion of police cars and patrol cars to shoot and record surrounding conditions of vehicles.

Description

Technical field: [0001] The invention relates to digital video camera and recording and broadcasting technology, in particular to an omnidirectional camera scene recorder capable of shooting a complete scene in all directions, and is mainly widely used in a field law enforcement and evidence collection instrument worn by security law enforcement officers when they are on patrol or on duty. Background technique: [0002] The progress of science and technology is promoting the progress of the rule of law. As a modern means of evidence collection, audio and video recordings have been widely used in the fields of criminal litigation, civil litigation, administrative litigation and administrative law enforcement. The birth of the law enforcement recorder has played an active role in law enforcement and duty, investigation and case solving, reception of letters and visits, protection of rights and interests, etc., and achieved good results.

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide an omnidirectional camera scene that is compact in design, easy to use, and capable of shooting a complete scene in all directions, in view of the limitation of the existing field recorder’s limited shooting angle and the inability to provide images in complex environments. A recorder, and a method for fast image distortion correction on the host to record and display various on-site situations without dead angle and distortion
