基于STM32的非接触物体尺寸形态测量系统

The measurement system of dimension and shape of non-contact object based on STM32

目前工件尺寸检测主要依靠机械式测量或人工测量,存在检测困难、效率低等问题。针对该状况,设计了一套非接触物体尺寸形态测量系统。该系统采用STM32单片机作为核心处理器;采用OpenMV和激光测距传感器作为非接触检测单元,以实现测量目标物体颜色、形状、尺寸及距离等信息的功能。同时,该系统中激光管的方向由舵机控制,以达到快速跟踪目标物体中心的目的。实验结果表明,该装置能够准确测量目标物体的颜色、形状,且可以得到高精度的物体尺寸及距离并快速跟踪目标物体的中心位置。

At present,workpiece size detection mainly depends on mechanical measurement or manual measurement,which is difficult to detect and low efficiency.Aiming at that situation,this paper designs a set of non-contact object dimension and shape measurement system.The system uses STM32 as the core processor.OpenMV and laser ranging sensor are used as the non-contact detection unit to realize the function of measuring the color,shape,size and distance of the target object.At the same time,the direction of the laser tube in the system is controlled by the steering gear,so as to achieve the purpose of fast tracking the target object center.The experimental results show that the device can accurately measure the color and shape of the target object,obtain the size and distance of the object with high precision,and quickly track the center position of the target object.
