Tilt photography is a high-tech developed in the field of international surveying and mapping remote sensing in recent years. By carrying multiple sensors on the same flight platform and collecting images from different angles such as vertical and inclined, more complete and accurate information of ground objects can be obtained, which breaks through the limitation that traditional aerial cameras can only shoot vertically to obtain orthographic images. Tilt photography technology is widely used in enterprise workshops, large buildings, garden construction, scenic spot development planning, landform investigation, large-scale open-pit mining and other fields.
Fast and efficient restoration of the real scene has been widely recognized by the market, and how to improve the accuracy of the model has also been deeply discussed in the industry.
