Abstract

The invention relates to the technical field of laser measurement, and particularly discloses an improved 3D laser scanning imaging system which comprises an outer frame and a pull rod connected withthe outer frame; a servo motor, a synchronous belt base, a linear sliding rail, a sliding block, a scanner and a scanner frame are arranged on the outer frame, and the servo motor is connected with the synchronous belt base through a synchronous belt. The sliding block is installed on the linear sliding rail, the scanner frame and the sliding block are both connected with the synchronous belt base, and the scanner is installed on the scanner frame. The improved 3D laser scanning imaging system is simple in structure and flexible in movement, can effectively guarantee the scanning imaging precision, and meets the production demands.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to an improved 3D laser scanning imaging system. Background technique [0002] The current 3D imaging systems are divided into: binocular 3D, grating structured light, and laser triangulation imaging; when the first two are measuring large depth of field, there will be problems with the image system defocusing after the measured object deviates from the imaging focal plane, causing measurement accuracy Significant decrease, and due to defocusing, the brightness of the light entering the individual pixel particles of the sensor is reduced, resulting in a significant reduction in the dynamic range of the system. Laser triangulation imaging converts the focal plane of a two-dimensional (x, y) image into an image containing depth information (x, z) through dimensionality reduction, thereby solving the problem of large depth of field, but due to the lack of y information in the...
