Laser scanning three-dimensional model-oriented multi-image automatic texture mapping method

The invention discloses a laser scanning three-dimensional model-oriented multi-image automatic texture mapping method which comprises the following steps: acquiring a three-dimensional point cloud model of a three-dimensional scene by a laser scanner, forming a corresponding triangular grid model, calculating the three-dimensional point cloud model of the three-dimensional scene and corresponding camera parameters by a multi-image three-dimensional reconstruction system, calculating a rotating matrix, a translation matrix and a zooming matrix between the triangular grid model and the three-dimensional point cloud model, and adjusting the triangular grid model to be overlapped with a multi-image three-dimensional reconstructed model so as to carry out automatic texture mapping on the adjusted triangular grid mode according to the camera parameters to obtain corresponding texture images. According to the multi-image automatic texture mapping method disclosed by the invention, the phenomenon that the conventional three-dimensional model mapping effect is poor is greatly improved, so that the whole texture mapping process is completed fully automatically, and the result quality is higher.
