Description

Technical Field

[0001] The utility model relates to the technical field of tilted photography, and more specifically to a swing-type three-lens tilted photography device. Background Art

[0002] With the development of UAV technology, its application fields are also gradually expanding. UAV oblique photography technology is a new photogrammetry technology developed on this basis. Different from traditional photogrammetry technology: oblique photography cameras are usually composed of a positive lens and multiple oblique lenses, mounted on drones, and take pictures of ground objects from different angles such as vertical and oblique. The image obtained by shooting at a vertical angle to the ground is called a positive film, and the image obtained by shooting at a certain angle between the lens and the ground is called an oblique film. Oblique photography technology is used to obtain image data as material, which can be automatically processed to obtain true orthogonal images (TDOM) and digital surface models (DSM), realize three-dimensional modeling of real scenes, quickly restore the real situation, and provide users with richer geographic information.

[0003] However, if traditional oblique photography needs to capture the three-dimensional modeling of real scenes, multiple cameras are needed to complete the entire picture of the three-dimensional modeling of the real scene through different tilt angles. Usually four plus one camera is selected. As the number of cameras increases, the factors that need to be considered will also increase, such as the weight of the drone, the heat generated by multiple cameras stacked together, or the camera's battery life. Therefore, swing photography can be used to compensate for the problem of fewer three-dimensional modeling pictures, while also reducing the weight of the drone.

[0004] Therefore, in order to solve the above problems, a swing-type three-lens tilt photography device is proposed. Utility Model Content
