  • Multi-line array laser three-dimensional scanning system, and multi-line array laser three-dimensional scanning method
    Patent number: 10267627
    Abstract: The present invention provides a multi-line array laser three-dimensional scanning system and a multi-line array laser three-dimensional scanning method, the system performs precise synchronization and logic control of the multi-line array laser three-dimensional scanning system by a programmable gate array FPGA; employs a line laser array as the projection pattern light source, sends trigger signals to a stereoscopic image sensor, a inertial sensor and a line laser array by FPGA; wherein a upper computer receives image pairs taken by the stereoscopic image sensor, and codes, decodes as well as performs a three-dimensional reconstruction for the laser line array patterns in the image pairs, performs a three-dimensional reconstruction for the feature points on the surface of the measured object, and matches and aligns the three-dimensional feature points at different times; the system predicts and corrects the matching calculation by employing a hybrid sensing technology, which registers and stitches the time
