Box camera and dome camera integrated dynamic face snapshotting special-purpose video camera and dynamic face snapshotting method

Abstract

The invention provides a box camera and dome camera integrated dynamic face snapshotting special-purpose video camera, which comprises an integrated machine body, a first camera module, a second camera module and a main control chip, wherein the first camera module and the second camera module are integrated in the integrated machine body, and are in communication connection with the main controlchip respectively; the first camera module is fixed to the front part of the integrated machine body, and is used for acquiring large-scale scene images; the main control chip is arranged inside the integrated machine body, performs preliminary detection on all targets according to the large-scale scene images and determines a target to be snapshotted; and the second camera module is arranged at the bottom part of the integrated machine body, tracks and magnifies the target to be snapshotted under the control of the main control chip, and acquires a face image of the target to be snapshotted.The invention further provides a dynamic face snapshotting method based on the box camera and dome camera integrated dynamic face snapshotting special-purpose video camera.

Description

technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to a gun-ball integrated dynamic face capture special camera and a dynamic face capture method. Background technique [0002] With the popularization of security monitoring equipment and the construction of a safe city, there are more and more front-end cameras in the public security and other monitoring systems. In the face of massive video data, how to reduce the video search time and extract effective information from the captured video in a timely manner has become an urgent need solved problem. [0003] Face comparison is the most effective way to find a specific person in the monitoring system, so the application of face comparison servers in the back-end platform has become more and more popular. However, in the front-end monitoring system, in order to meet the requirements of the face comparison system for the pixel width and definition of the face, currently onl...

Problems solved by technology

However, in the front-end monitoring system, in order to meet the requirements of the face comparison system for the pixel width and definition of the face, currently only cameras with fixed angles and fixed focal lengths can be used for narrow channels (below 3 meters in width) to realize face detection. Snapshots, but for wider channels or larger square areas, fixed focal length guns cannot effectively solve the problem of face shooting
