Advantages of tilt photography modeling technology

Traditional 3D modeling usually uses 3dsMax, AutoCAD and other modeling software. Based on the information such as image data, CAD plan or photographed pictures, manual modeling is carried out to estimate the outline and height of buildings. The model data made in this way has low accuracy, and the texture deviates greatly from the actual effect, so the production process needs a lot of manual participation; At the same time, the data production cycle is long, which leads to the low timeliness of data and can not really meet the needs of users.

Tilt photogrammetry technology can comprehensively perceive complex scenes in a wide range, with high precision and high definition. The data results generated by efficient data acquisition equipment and professional data processing flow directly reflect the appearance, position, height and other attributes of ground objects, ensuring the real effect and surveying and mapping accuracy. At the same time, it can effectively improve the production efficiency of the vehicle. Manual modeling takes one or two years to complete the modeling work of a small and medium-sized city, and oblique photography modeling only takes three to five months to complete, which greatly reduces the economic cost and time cost of 3D model data collection. At present, tilt photogrammetry technology has been widely used at home and abroad, and tilt photogrammetry modeling data has gradually become an important content of urban spatial data framework.
