What types can UAV tilt cameras be classified according to different classification standards?

Can be divided into aerial photography and tilt.

UAV tilt photography technology can be widely used in geological disaster investigation, monitoring, early warning, evaluation and emergency site disposal of geological disasters. Although the UAV tilt photogrammetry technology has realized the automatic data processing, due to the high overlapping rate of heading and lateral direction, even a small area coverage needs a lot of data, and the processing process is quite time-consuming and requires high computer software and hardware. The research on UAV data rapid processing system and disaster rapid analysis and interpretation technology can effectively improve the practicability and effectiveness of UAV tilt photography and promote the wide application of UAV remote sensing in geological disaster investigation and monitoring and geological disaster emergency.

Oblique photography is photography in which the main optical axis of the camera obviously deviates from the vertical or horizontal direction and is shot at a certain inclination. Tilt camera is a kind of airborne equipment, which is characterized by consisting of five high spatial resolution area array digital cameras, which are installed on the stable platform of aerial photography at a certain angle. The photographing device of high spatial resolution area array digital camera includes down-looking camera, forward-looking camera, back-looking camera, left-looking camera and right-looking camera. Down-looking camera is vertical photography, which is used to make DEM and orthophoto. Forward-looking camera, backward-looking camera, left-looking camera and right-looking camera are all oblique photography, which is used to obtain the side texture image of ground objects, and the inclination angle is between15-45. Accurate alignment of imaging time is carried out between cameras through a time synchronization device; The attitude and position parameters of the image are provided by the attitude measuring equipment. It has a computer control system and a data storage device, which is responsible for data acquisition and control of the above components, sends homologous trigger signals to start multi-table array cameras, and realizes synchronous data acquisition and storage maintenance. Through the corresponding tilt image data processing software, the collected tilt image is preprocessed, including a series of processing such as color matching, correction, correction, stitching, fusion, etc., to form a tilt image data product that meets the application requirements.
