The inverted scanning incident angle technology was researched, and the hardware tripod inverted installation conditions were determined to attain a reasonable scanning incident angle and achieve a good acquisition effect of point clouds. On the software side, the technology of efficient and automatic noise removal was examined to realize the automatic and efficient removal of noise in inverted scanning. Through experimental comparison, the key technology of 3D laser inversion scanning can be used to achieve better inversion scanning and scanning results. Moreover, it can be used to reduce the intensity of work, improve work efficiency, and expand the application field of 3D laser scanning. The application fields of 3D laser scanning technology have expanded, and can be used as a reference in the application of inverted scanning technology, automatic and high-efficiency noise processing technology, and so on. Furthermore, this method provides a reference for infrared technology in image fusion, image information recognition, image noise reduction, and so on.
