Photoelectric multi-dimensional displacement automatic measuring device

The utility model discloses a photoelectric multi-dimensional displacement automatic measuring device, and relates to the field of engineering safety monitoring. The measuring component is composed of a lens cone, a light source, a cross reticle, a projection lens and a four-CCD measuring circuit board, the four-CCD measuring circuit board is installed at the front end of the lens cone, a round hole is formed in the middle of the four-CCD measuring circuit board, light can pass through the round hole, the four linear array CCDs are symmetrically arranged around a light through hole, and the light sensing face faces forwards. The light source at the rear end in the lens cone illuminates the glass cross reticle, a cross curve image is projected by the lens, and the cross curve can be clearly imaged on the CCD photosensitive array on the opposite side by adjusting the distance between the reticle and the lens. By collecting and processing CCD signals, the X and Z coordinates of the cross point of the cross curve
