| Numbering | Method | Advantage | Disadvantage |
|
| 1 | A method based on mapping terrain data | Eliminate the cost of primary data, high model accuracy | Fundamental data is challenging to obtain, data cost is high, the cycle is long, timeliness is poor, and human interaction is prominent |
|
| 2 | A method based on DEM data is greatly affected by terrain and features | A wealth of information to simulate complex buildings | DEM data is costly and difficult to obtain due to terrain and ground objects |
|
| 3 | A method based on image recognition technology | Convenient and cheap | Lack of a unified framework to guide the accuracy and efficiency needs to be improved, lack of research on the building complex |
|
| 4 | A method based on three-dimensional laser scanning technology | Point cloud data with high precision and architectural details in place | Need professional equipment, point cloud processing complex, a large amount of manual interaction, high cost, long cycle |
|
| 5 | A method based on paper intelligent identification technology of building vector | Take advantage of existing resources | Strict format and precision, only for small scale |
|
| 6 | A method based on CSG modeling technology | Fast modeling speed, simple structure, a small amount of data | It is difficult to break down complex shapes |
|
| 7 | Process building modeling method | Fast modeling speed, easy to control and adjust parameters, challenging to promote | High technical threshold, complicated operation, and difficult promotion |
