LIDAR point cloud data coordinate conversion method

The invention discloses an LIDAR point cloud data coordinate conversion method, which comprises the following steps of 1, reading data, and obtaining source LAS record coordinates of points; 2, converting the source LAS record coordinates into source actual coordinates through coordinate conversion; 3, selecting a proper coordinate conversion model, and performing model conversion on the source actual coordinates to obtain target actual coordinates; 4, performing inverse coordinate transformation on the actual coordinates of the target to obtain LAS record coordinates of the target; the problems that an existing conversion method is too high in cost, single in conversion method, low in efficiency and the like are solved. 本发明公开了一种LIDAR点云数据坐标转换方法，包括以下步骤：步骤1：读取数据，获得点的源LAS记录坐标；步骤2：通过坐标变换，将源LAS记录坐标转换为源实际坐标；步骤3：选择适合的坐标转换模型，对源实际坐标进行模型转换，得到目标实际坐标；步骤4：对目标实际坐标进行逆坐标转换，得到目标LAS记录坐标；本发明解决了现有转换方法成本过高、转换方法单一、效率低等问题。
