Description

technical field [0001] The invention relates to the technical field of laser three-dimensional scanning, in particular to a high-speed laser three-dimensional scanning system, which uses optical emission and reception optimization to improve scanning speed. Background technique [0002] Laser three-dimensional scanning technology usually uses a unit photoelectric sensor to receive echo signals to obtain ranging data, and combines the vertical and horizontal two-dimensional scanning angle data to reconstruct the three-dimensional point cloud of the measured target. At present, the fastest scanner can scan a 360-degree panoramic image within 1 minute at the fastest, but the resolution of the image collected by scanning in this time is too low to meet the actual surveying and mapping needs. For this reason, field operators will further select areas of interest on the basis of this image for precise high-resolution acquisition. This way of working has actually prolonged the ope...
