Moving body image tracking acquisition method and system

Abstract

The invention relates to a moving body image tracking acquisition method and system, and belongs to the technical field of video acquisition. When the moving body is located outside the first image acquisition range and the moving body and the moving body just enter the second image acquisition range, the first image acquisition range can be moved to the moving body by calculating a first displacement angle from the first image acquisition range to the second image acquisition range; and when the moving body moves in the second image acquisition range, a second displacement angle of movement of the second image acquisition range is calculated, and conversion is performed to obtain a third displacement angle of the first image acquisition range, so that the first image acquisition range moves along with the movement of the moving body, and video acquisition of the moving body is always kept.

Description

technical field [0001] The invention relates to the technical field of video acquisition, in particular to a method and system for tracking and acquiring images of moving bodies. Background technique [0002] The automatic tracking camera is an all-in-one camera that integrates and expands the functions of the lens, pan / tilt, and ordinary camera. The automatic tracking camera can automatically identify image information. When the image moves, it follows the movement to capture the image. The pan / tilt is automatically controlled to track moving objects, and all movements of the objects are clearly transmitted to the monitor. [0003] In the prior art, once a moving body enters the shooting screen, the automatic tracking camera can move according to the movement of the moving body, so as to capture the state of the moving body at all times. However, when the moving body does not enter the shooting frame, the automatic tracking camera cannot focus on the moving body. This is ...

Problems solved by technology

However, if a wide-angle lens is directly used, the number of lenses and the number of groups of the wide-angle lens are large, and the low-end wide-angle image quality will be lost more, and the structure of the zoom wide-angle lens is more complicated, and the image quality of the fixed-focus wide-angle lens is more serious. Although the technology These difficulties can be overcome, but the cost has obviously increased a lot
