Industrial photogrammetry system calibrating device

The invention relates to the technical field of photogrammetry, and discloses an industrial photogrammetry system calibrating device. The device comprises a granite platform, wherein the upper surfaceof the granite platform is fixedly connected with three granite stand columns including the first granite stand column, the second granite stand column and the third granite stand column, and the upper surface of the granite platform is fixedly connected with a granite block. According to the industrial photogrammetry system calibrating device, seven accurately calibrated carbon fiber reference rulers are arranged, and each reference ruler has five reference lengths. A cubic space coordinate system is established, the industrial photogrammetry system measures the reference length of each section of the carbon fiber ruler at different positions and different angles, and the measurement result is compared with the actual reference length of the carbon fiber ruler according to the verification regulation, so that th
