Paper Abstract

At present, the verification method of hand-held laser range finder has characteristics of high labor intensity, low working efficiency and low measuring accuracy. To solve these problems, an automatic hand-held laser range finder verification system is built in this paper. This system contains a 50m marble calibration platform, a measuring trolley with visual measuring module, and a multi-degree of freedom holder of range finder. It can automatically identify the observed readings of rangefinder through optical character recognition (OCR) technology, compare with the standard ranging value obtained by the trolley, and then evaluate error of indication. Thus achieving the purpose of calibrating the rangefinder. All of the communication between PC and trolley is realized by WiFi. Experiments show this device has comprehensive functions, high level of automation, practical application value and broad market prospects.
