The problem of low precision exists in current measurement techniques. This paper introduces the structure and working principle of the liquid level measurement system of laser triangulation and carries out a high-precision real-time on-line measurement of the water surface height variation by using the liquid level measuring system. This paper introduces the structure of the laser triangulation displacement...
Designed for measuring the level of liquid, this system based on charge-coupled device (CCD), in combination with laser triangulation method and graphic program language of labview, accomplished signal acquisition and processing. By making experiment with this system and analyzing experiment data, the system has achieved the accurate experiment result. In this paper, it introduced the philosophy of...
