激光线扫描（LLS）是水下光学成像方法之一，它可以有效地减小后向散射和前向散射的不利影响。针对水下测量的需要，提出了一种基于激光测距系统的三维重建方法。通过摄像机直接标定，建立了二维像素坐标与三维世界坐标之间的映射关系，从而实现了由二维扫描数据重建三维物体。在水池中进行了实验，可以重建出毫米级的水下三维场景，表明该方法可以用于水下测量。
Laser line scan (LLS) is one of the underwater optical imaging methods, which can reduce the detrimental effects of backscatter and forward scatter. This paper put forward a 3D reconstruction method based on the LLS system, for the purpose of underwater surveying. By direct camera calibration, a coordinate mapping relationship between 2D pix coordinate and 3D world coordinate is established, which then can be used to reconstruct 3D objects from 2D scan data. Experiments had been carried out in a pool, and underwater 3D scene can be reconstructed at millimeter scale, which demonstrated that this method can be used to underwater surveying.
