Abstract :
An outdoor 3D (three-dimensional) information traverse acquisition system based on range data reconstruction solid image is introduced. The system has two laser scanning distance meters mounted on the roof of the vehicle, and the horizontal and vertical data are sampled separately. As the vehicle moves ahead, a horizontal and a vertical range profile of the surroundings are captured at each trigger. According to the captured data, the solid image is restructured through vertical range profiles are aligned to the coordinate system of horizontal one. The accuracy and efficiency of traverse measurement system be improved by means of the cost function calculation and range profiles matching
