Moving body image tracking acquisition method and system

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. 本发明涉及一种运动体图像跟踪获取方法及其系统，属于视频采集技术领域。在运动体位于第一图像采集范围外，且与运动体正好进入第二图像采集范围内时，通过计算第一图像采集范围至第二图像采集范围的第一位移角度，可使第一图像采集范围移动至运动体上；当运动
