Research On Non-contact Measuring System Of Distance And Dangerous Targets

In the actual process of field production or science research, researchers often encounter the situation that need us to measure the dangerous target involving personal safety, or we can’t get near. So we can’t accurately measure the related parameters to distant targets. In the paper, we base on the need of production or science, using modern photoelectric detection technology, in detail described the principles based on distant laser ranging to measure relevant parameters of distance targets, and designing a measuring system to achieve the length and height non-contact measurement of a greater distance. Meanwhile we conduct a more detailed introduction to the main technical.The system uses the laser alignment technology, laser ranging technology and the technology of the optoelectronic angle measuring, to achieve the alignment、range of the measured object, in the process we can effectively solve the problem in the actual field production or science research. Meanwhile according to the designing needs, we through experiments collect、analyze、deal with the measured data. In the end we achieve accurately measuring the related parameters to distant targets.This paper in detail analyze various error factors impacting measurement results, such as the alignment error、laser ranging error、the angle measuring error and other factors, through calculating and analysis the influencing factors, we further improve the measuring system.
