摘　　要：为满足移动机器人系统中对环境物体定位的需要,在ARM-LINUX平台上,设计了障碍物形状识别系统.根据超声波测距原理,设计了"一发三收"式的超声波探测装置,利用数字示波器采集不同形状障碍物的超声波回波数据.通过比较分析,可分辨出障碍物的边角形状,并通过大量实验来验证系统的有效性.An obstacle shape recognition system based on the ARM-LINUX platform is de-signed for object location using in a mobile robot system. Based on the ultrasonic ranging principle, we design a ＂one-trig-three-receive＂ type ultrasonic detection device. The ultra- sonic echo data of different shapes of obstacles are collected and analyzed by a digital oscillo- scope, then by comparison and analysis, different shapes of obstacles can be distinguished.The validity of the proposed scheme is verified by a large number of experiments.
