Abstract:

In the project of testing platform, characteristics of the measured object are framework. In view of the difficulties of non-contact high-precision measurement of the planar motion objects, an innovative measuring method is proposed which is based on the combined using of high-precision laser distance sensors. This paper presents the structure of the new sensor and its measuring principle, and established a mathematical model of the measurement object and its error model by using differential method. We use the Monte Carlo method to random sample the random sampling of random variables of the error model; finally combining with the instance; we use the Monte Carlo method to get frequency distribution histogram of the measurement error. Through analysis and calculation of this paper, we prepare for theory for the practical application of this new type of sensor.
