【Abstract】 In order to adapt to the cultivation of modern applied talents, and improve the students’ comprehensive practical ability, a laser triangular contour scanning system is designed. In this system, PSD is used as photoelectric detection element to form a double lens laser triangulation probe, and a single-chip microcomputer control system is used to drive the probe motor to scan the X-Y plane and measure the height Z of the object. In real time, the measurement results are transmitted to MATLAB through serial communication to realize the real-time display of 3D contour. This design integrates electronic technology, optoelectronic technology, single-chip microcomputer, MATLAB, photoelectric detection and other electronic and optoelectronic professional basic technology courses. This design has strong individual foundation, and can be used as a practical teaching model for the cultivation of application-oriented talents in related majors.更多还原
