Example Embodiment
[0031] Next, the present invention is further described in conjunction with the accompanying drawings and the specific embodiments, and it is to be explained that new embodiments may be formed in any combination of the various embodiments, or each of the technical features, or each of the technical features. .
[0032] Natural shoreline automatic acquisition method based on laser point cloud data and average tide galvan surface, such as figure 1 As shown, including the following steps:
[0033] Get the laser point cloud data, use drone airborne laser radar, low-altitude remote sensing equipment, ground remote sensing equipment to deck the laser point cloud data of land to tide zone; laser point cloud data contains latitude coordinates (x, y ), Elevation H1, measurement of error M and other necessary information. Since natural shoreline is a average tide gave trace line, in order to obtain the complete natural shore laser point cloud data, the time for laser point cloud data collec...
