Utility model content
The purpose of this utility model is to provide a kind of compact conformation and makes easily for the optical measuring instrument of measurement target thing size, and it is with the distance of two directional lights for measuring basis, and measuring accuracy is high, ensures the accuracy measured.
The purpose of this utility model realizes by the following technical solutions, and it comprises bracing frame and generating laser, and generating laser is two, and what two generating lasers paralleled is arranged on bracing frame, and the light source that two generating lasers send is parallel to each other.
The utility model passes through the generating laser of two parallel installations to measured target surface launching two sources of parallel light, article two, source of parallel light is penetrated and form two measurement points on measurement target face, again target face is taken photos, with the benchmark of the parallel distance of two sources of parallel light for converting, the measuring distance of the measurement point of two on photo is converted in proportion with the distance of two actual directional lights and draws benchmark ratio, finally measure the length and width of the target face on photo or high measured value and benchmark ratio and change in proportion to obtain target face length and width or high actual value.Because the distance between two sources of parallel light is exact value, then with the distance between two directional lights for benchmark, then can ensure the accuracy measured, improve the precision measured.
Owing to have employed technique scheme, the utility model has the advantage of compact conformation, easy to assembly and good looking appearance, and it is with the distance of two directional lights for measuring basis, and measuring accuracy is high, ensures the accuracy measured.
