AI Technical Summary
Traditional project investment management systems often fail to accurately map projects or are too costly, making it difficult to provide the precise scope of project construction. Furthermore, high-resolution remote sensing satellite imagery data is prohibitively expensive and cannot accurately determine the actual project scope.

The latitude and longitude are matched to accurately land the points on the electronic map. The regular trajectory point set is cleaned and the marker trajectory point set is repaired. Finally, the points are connected in chronological order to form a detailed map of the project scope.

The repair module is used to repair the abnormal trajectory points of the marker trajectory point set on the coarse map of the project scope to obtain the target marker trajectory point set; The second mapping module is used to re-land the trajectory points in the target marker trajectory point set on the electronic map and connect them with the trajectory points in the adjacent target regular trajectory point set to form a detailed map of the project scope. The association module is used to associate the project information with the detailed project scope map to complete the project mapping.
7. The project mapping system according to claim 6, characterized in that, The second acquisition module is specifically used for: Confirm the starting point of the trajectory points sent by the positioning device; The trajectory points sent by the positioning device are acquired according to a preset time interval until the positioning device forms a closed loop along the project boundary from the starting point, thus obtaining the trajectory point set.
8. The project mapping system according to claim 6, characterized in that, The landing point module is specifically used for: Delete trajectory points in the regular trajectory point set that are missing coordinate attributes and / or coordinate generation time attributes; For multiple trajectory points with the same coordinate attributes within the set of regular trajectory points, only one of them is retained; Based on the project information, obtain the latitude and longitude range of the administrative region where the project is located, and eliminate trajectory points that fall outside the latitude and longitude range; The remaining trajectory points in the set of conventional trajectory points are smoothed and denoised to complete the cleaning of the set of conventional trajectory points and obtain the target set of conventional trajectory points.
9. The project mapping system according to claim 6, characterized in that, The repair module is specifically used for: The trajectory points within the set of marker trajectory points are highlighted on the coarse map of the project scope, and it is determined whether the highlighted trajectory points correspond to the project boundary marker points. If the highlighted trajectory point corresponds to the project boundary marker point, then the highlighted trajectory point will be retained. If the highlighted trajectory point does not correspond to the project boundary marker point, the highlighted trajectory point is retrieved again until it corresponds to the project boundary marker point, and finally the target marker trajectory point set is obtained.
10. The project mapping system according to claim 6, characterized in that, The association module is specifically used for: The project information includes geographical location, project name, and project status. A project identifier is generated on the electronic map based on the geographical location, and the project identifier is linked to the detailed map of the project scope. Associate the project name with the project scope map; Configure the color attributes of the project scope map according to the project status to complete the association between the project information and the project scope map.
