Abstract

The invention discloses a video image obtaining method, system and device. The video image obtaining method comprises the steps that original video image acquisition is conducted on a scene to be acquired by means of a high-definition camera; each time an original video image is acquired, a video image which corresponds to each area to be acquired in the scene to be acquired is generated in the same original video image by combining the electronic amplifying technique with the image clipping technique, wherein the number of the areas to be acquired is M, and M is a positive integer which is larger than one. By the adoption of the scheme, both manpower sources and material resources can be saved, and the realizing difficulty can be lowered.

Description

technical field [0001] The present invention relates to the field of video applications, in particular to a video image acquisition method, system and device. Background technique [0002] In the prior art, for a larger scene to be captured, usually multiple cameras are used to capture video images for multiple areas to be captured. [0003] figure 1 It is a schematic diagram of an existing scene to be collected. Such as figure 1 As shown, the scene includes three areas to be collected, which are the area to be collected 1, the area to be collected 2, and the area to be collected 3; for each area to be collected, a network camera or an analog camera is respectively arranged, and each camera Real-time video image acquisition is performed on the corresponding areas to be acquired respectively. [0004] Among them, the three cameras can work synchronously, and convert the collected video images into network code streams through encoding, and send them to the client; corresp...
