Research on processing and analysing of point cloud data of a variety of lidar

According to the engineering application of tunnel measurement, designed two technology solutions, separately using two 3-d laser scanner with different distance measurement principle to obtain the space information of the same tunnel simulation scenario, analysis and comparison data, conclude the reliability and quality of alternative. There are a variety of styles point cloud of target in the same scene in test of two kinds of 3-d laser scanner to identify the target recognition and measurement accuracy. Before implementation, designed experiments to test the factors associated with technical solution design such as the two station 3-d laser scanner log size, accurate, and the influence of incident Angle on the measuring accuracy and technology.
