Problems solved by technology

[0003] The capture of traditional surveillance cameras (such as traffic vehicle surveillance cameras, high-altitude parabolic surveillance cameras, etc.) adopts lag capture, that is, the capture starts after the event occurs. There is a gap between the event occurrence and the capture time in this capture method Time difference, so there will be an incompleteness in the captured image information, and there may be missed shots for objects that move at high speed and for a short time

Abstract

The invention discloses a device and method for a camera to snapshot advance and delayed images. The device comprises a processor, a video processing module and an acquisition image storage module; a time judgement module for judging a time point in need of being snapshot is between the acquisition image storage module and the video processing module; an advancing module, a buffer module and a delaying module are respectively connected between the time judgement module and the video processing module; and the video processing module is connected to the processor. The device disclosed by the invention snapshots an image at the occurrence time point ti of an event, simultaneously snapshots images in the advance time slot t and the delayed time slot t' of the time point ti, and processes all the snapshot images to form a continuous video; by means of the linear acquisition manner, the image of an object moving at high speed and having a short moving time can also be clearly displayed on the snapshot video; and the device provided by the invention is applied to monitoring systems of all kinds of monitoring cameras.

Description

technical field [0001] The present invention relates to the field of cameras, in particular to a capture device used for camera capture in advance and delayed imaging. [0002] The present invention also relates to a capture method for camera capture in advance and delayed imaging. Background technique [0003] The traditional surveillance cameras (such as traffic vehicle surveillance cameras, high-altitude parabolic surveillance cameras, etc.) are all captured by lag capture, that is, only after the event occurs. Due to the time difference, the captured image information will be incomplete, and there is a possibility of missing shots for objects that move at high speed and have a short moving time. Therefore, how to improve the capture accuracy of surveillance cameras so that the images of objects that move at high speed and have a short moving time are clearly visible has become an urgent technical problem in the field of surveillance cameras. SUMMARY OF THE INVENTION ...
