Study on cable length measurement methods

With the development of digital image processing, traditional contact measurement cannot satisfy the accuracy needs of the cable length measurement. The technology of non-contact photoelectric detection is becoming more and more practical. Using optical mouse chip to test motion can effectively avoid the system errors brought by touching with things. Under this background, we design a non-contact measurement equipment that is based on MCU system, to measure the length of cable for cable manufacturers. The experimental results show that it could meet the engineering needing.
