一种快速求运动目标重心的方法

A Method for Quickly Calculating the Centre of Gravity of a Moving Target

介绍一种方法,用硬件统计一幅图像中被测目标的两维空间分布,然后用高速信号处理器 TMS32010计算并实时输出被测目标在视场中的位置。此方法的特点是速度快,全视场求重心只用1.3ms;精度高,定位误差≤1个象元;抗干扰性强;对于椒盐噪声及动态拖尾造成的影响均可经过统计平均予以消减。这种方法适用于高速、高帧频和高精度的电视自动跟踪和测量。

This paper introduces a method using hardwares to count up the 2-D spatial distribution of measured targets in a frame of image,and using high speed signal processor TMS32010 to calcul- ate and output the place of the targets. The time of calculating the centre of gravity of the targets within whole field of view is 1.3ms. The position error≤1 pixle. It can eliminate or abate the influence caused by spiced salt noise and dynamic sluggishness. It is suitable for automatically tracking and measuring fast moving targets with high precision.
