A Study of the Deviation Causes of Non-contact Laser Measurement based on Orthogonal Test

Non-contact laser measuring device （Gap-gun） is applied to the measure the flushness and the gap of finished vehicle. The measuring angle, the laser intensity, and the color of the body determines a lot of the precision of the results as a key factors. In this paper, orthogonal test is used to study the effects of these factors. The test result shows the best combination of the factors and proves to be a valued guidance to engineering.
