摘要
针对传统接触式测距方法的局限性,介绍了一种根据光学三角法利用图像传感器近距离测距的方法。通过半导体激光器发出的光经过物体反射成像在CMOS图像传感器的光敏面上,接受到的激光光斑图像通过接口传到主机,利用Matlab进行分析处理计算,得到被测距离。通过搭载模拟实验平台,验证了该方法的可行性,并且简单易于实现,有较高的实用价值。
Because of the limitation of the tradi- tional contact range finding method, according to the optical triangle method using image sensc^r for short distance measuring method. The semiconductor laser emits light after reflection imaging of objects in a CMOS image sensor photosensitive surface, the received laser spot image through the in-erface to the host, using Matlab analysis calculation, get the distance measure. Through the flight simulation platform, to verify the feasibility of the method,which is simple and easy to realize, has a high practical value.
