Abstract:The ecological environment in an earthquake disaster area is complicated, and area restoration is easily affected by related information. Therefore, the ecological environmental restoration process is complex, and the repair effect is not ideal. In this paper, a three-dimensional model for post-earthquake regional ecological environmental restoration based on laser scanning was designed. Raw data of the tailed position of the natural landscape and facility were acquired through three-dimensional laser scanning. The plane characteristic image segmentation method was used to geometrically correct the original data. Whole data correction and matching was then completed. The normal vector was then used to minimize the modified ecological environment data, and splicing and matching information was obtained. According to the matching information, the re-sampling was carried out to construct the three-dimensional grid model and obtain the overall data from the ecological environment after a regional earthquake disaster. Based on the model, the physical area of the terrain brush was constructed to repair the damaged terrain environment after the earthquake disaster. The method was then applied to the restoration of the ecological environment after the earthquake in a certain disaster area. Results proved that the method has use value.
