Problems solved by technology
Without considering the factor of aircraft speed, the aerial photography efficiency of the digital tilting aerial camera mainly depends on the format of the downward-looking single camera. Due to the limitation of development, the method of improving the imaging format of a single camera seriously restricts the efficiency of digital oblique aerial photography

The invention relates to the technical field of aerial photography, and discloses an ultra-large-breadth inclined aerial camera. The ultra-large-breadth inclined aerial camera comprises a camera tray,a first oblique-view camera, a second oblique-view camera, a third oblique-view camera, a fourth oblique-view camera and a downward-view camera assembly, and the first oblique-view camera, the secondoblique-view camera, the third oblique-view camera, the fourth oblique-view camera and the downward-view camera assembly are installed on the camera tray.The left breadth and the right breadth of a target object are shot through the first oblique-view camera and the third oblique-view camera; the front breadth and the rear breadth of the target object are shot through the second oblique-view camera and the fourth oblique-view camera; the upper breadth of the target object is shot through the downward-view camera assembly; the downward-view camera assembly comprises a first single camera and asecond single camera, or the downward-view camera assembly comprises double cameras. The breadth of the downward-view camera is expanded through subsequent data splicing. The aerial photography efficiency can be effectively improved, the long side directions of the first oblique-view camera and the third oblique-view camera are perpendicular to the course direction and rotate by 90 degrees, the lateral coverage area is increased, and what is guaranteed is that the overlapping degree of oblique-view camera images meets the requirement.
Description
technical field [0001] The invention relates to the technical field of aerial photography, in particular to an ultra-large format inclined aerial photography instrument. Background technique [0002] Tilt photogrammetry can not only truly reflect the situation of ground objects, but also can embed accurate geographic information, richer image information, and more advanced user experience through advanced positioning technology, which greatly improves the speed of aerial image processing. Tilt photography technology has been widely used in digital earth, smart city, smart agriculture and other fields. The principle of tilt photography is that one shot can simultaneously obtain the top surface and side texture image data of ground objects, so as to establish a real 3D model. [0003] The traditional oblique aerial camera for obtaining large-area oblique photography data is composed of five single cameras, one of which is downward-looking single camera to obtain the top textur...
