Elbow-Fixed Distance Measuring System with Using MEMS and Laser Module, Encoder Measurement System

摘要

In recent years, various products using laser distance measuring modules have been on the market. The advantage of measuring distance using laser is that it is cheaper than using camera to analyze pictures, but the resulting value within the measurable range is never inferior. However, there is a disadvantage of the laser, which one is pointer of laser should be visible. If not, it can't be measured. And also, it is according to the material of the object. Above all, a single laser module can only measure the length between the device and the target object. So in this study, a variety of modules were applied to a single laser module to study how to measure the length between two points with small ease.
