| 摘 要： | 本文提出了跟踪运动物体的卡尔曼滤波器的完整设计过程.滤波器是在TMS320数字信号处理器(DSP)上实现的,和模拟结果比较,分析了滤波器的精度及量化误差的影响.尽管该滤波器是专用DSP构造的,但设计方法也适用于其它类型的DSP.该滤波器可以用来滤除运动物体位置测量信号中的噪声.对一个二维运动物体,单字长精度的滤波器带宽可达1.68kHz.

| Abstract: | A complete design of kalman filter for tracking moving objects ispresented.The filter is implemented on a TMS320 digital signal processor.Tracking accuracy and quantization effects of the implementation have been mesured by comparing the filter to one implemented on a eneralpurpose computer.Although it is implemented on a specific signal processing chip, the design is general enough to be applicable to any other digital signal processor (DSP).the filter can be used for tracking anymoving object whose position measurements are contaminated by noises,Formotion on a plane, the filter can be used to track objects where the maximum system bandwidth is 1.68 kHz. |
