Three -dimensional appearance measuring device based on digital holographic scanning

The utility model discloses a three -dimensional appearance measuring device based on digital holographic scanning, including the volume of moving a dynamic testing device and digital holographic detection module, the digital holographic detection module assembly is on the volume of moving a dynamic testing device, digital holographic detection module is last to be equipped with and to measure workpiece for measurement plane to the laser range finder of the planar distance of CCDCMOS image sensor window, and the record distance through laser range finder obtains the interference strength information that CCDCMOS image sensor went up the thing light wave and referred to the light wave, realize that digital holographic detection module measures the large -scale workpiece surface of awaiting measuring region under the drive of the volume of moving dynamic testing device. The device measures regional three -dimensional model through the antithetical phrase and carries out laser rangefinder and image mosaicking, o
