为了解决高帧频大面阵数字摄像机数据量大,跟踪器实时性很难满足的问题,设计了基于双数字信号处理器TMS320C6203B的电视跟踪平台,合理组织双数字信号处理器的图像数据,即其中一个数字信号处理器用于全视场捕获目标,使运算量减少了数倍;另一个数字信号处理器根据捕获到目标大小和位置确定跟踪区域,在跟踪区域内进行全分辨率跟踪,既实现了快速目标捕获,同时又保证了跟踪精度。此系统在保证实时性的前提下,实现了对帧频为74 Hz,面阵为1 280×1 024的数字摄像机多达5个目标的跟踪。
In order to solve the problem that the large frame rate digital camera of high frame rate is large and the real-time performance of the tracker is hard to be satisfied, a TV tracking platform based on dual digital signal processor TMS320C6203B is designed to reasonably organize the image data of dual digital signal processor One of the digital signal processors for full field of view capture target, so that the amount of computation reduced by several times; another digital signal processor to capture the target size and location to determine the tracking area, the tracking area full resolution tracking, both to achieve Fast target capture, while ensuring tracking accuracy. This system realizes the real-time under the premise, has realized to the frame frequency is 74 Hz, the face array is 1 280 × 1024 digital camera tracking up to 5 goals.
