Design and Implementation of CMOS Single-line Laser Ranging System Based on MCU
Using linear array sensor based on FPGA for the range of triangle,there are problems such as complex systems,large structure sizes,high prices,small wide angles,and so on.In view of the above problems,this paper takes MCU as the main control of the system and drives the area array sensor and the line laser to complete the CMOS image data acquisition.According to the laser range of triangle,system parameter optimization,system calibration and other key technical modules are designed,and the functional verification of ranging is completed.The millimeter-level precision distance measurement of 30~170 mm can be achieved,and the point cloud depth information is output by UART,and the frame rate can reach 25 frames per second.The experimental results show that the designed triangular laser ranging system has millimeter-level precision,small structure size,large wide angle,and other advantages,which can be applied to the front obstacle detection of household sweepers.
