Embodiment Construction

[0066] In the embodiment of the present invention, a new solution is provided to solve the problems of smear and low image stability in shooting multiple moving objects. The solution is: based on the obtained center points of the detection frames corresponding to each moving object in multiple frames of images, determine the center point offset of the average detection frame corresponding to each moving object; based on the center point offset of each average detection frame to determine the movement information of each moving object; based on the preset exposure rules, the maximum exposure time corresponding to each movement information is determined as the maximum exposure time corresponding to each moving object, and according to the corresponding maximum exposure time for each moving object to shoot.

[0067] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0068] refer to figure 1 As shown,...

Abstract

The invention relates to the field of video monitoring, and discloses a shooting method and device of multiple moving objects, which are used for solving the problems of smear and low picture stability, and the method comprises the following steps: determining the central point offset of an average detection frame corresponding to each moving object based on the acquired central point of the corresponding detection frame of each moving object in a plurality of frames of images; determining movement information of each moving object based on the central point offset of each average detection frame; and based on a preset exposure rule, determining the maximum exposure time corresponding to each piece of moving information as the maximum exposure time corresponding to each moving object, andshooting each moving object according to the corresponding maximum exposure time. The corresponding maximum exposure time is determined according to the movement information of each moving object, andeach moving object is photographed according to the corresponding maximum exposure time, so that the exposure time does not need to be adjusted, the picture stability is improved, and the problem ofsmear existing in photographing of a plurality of moving objects is solved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and device for shooting multiple moving objects. Background technique [0002] With the development of science and technology, the clarity of surveillance images taken by surveillance cameras is constantly improving. However, when surveillance cameras are shooting moving objects, the surveillance images often appear blurry, smearing, and other unclear situations. At present, in order to solve the smear problem of shooting moving objects in the prior art, the following solutions are adopted to shoot moving objects. [0003] Specifically, acquire the first image of the moving object taken in the automatic exposure mode; then determine the moving speed of the moving object, and determine the exposure time corresponding to the moving speed, and acquire the second image of the moving object taken based on the exposure time; finally , performing image synthesis processing on t...
