Embodiment Construction
[0029] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
[0030] An embodiment of the present invention provides a method for optimizing the configuration of the azimuth elements of the aerial camera, such as figure 1 shown, including:
[0031] Step S11: Generate a pre-selected range of focal lengths of the downward-looking sub-camera, and determine from the pre-selected range of focal lengths of the downward-looking sub-camera according to the predetermined spatial resolution of photographic images, the predetermined frame size and pixel size of the sub-cameras Downward-looking sub-camera focal length range;
[0032] Step S12: Generate the tilt angle preselected range of the tilt sub-camera and the tilt sub-camera focal length pre-selection range, and determine the installation of the tilt sub-camera from the tilt angle pre-selection range according to the predetermined...

The invention relates to the technical field of aerophotography, in particular to an optimal configuration method for an orientation element of an aerial camera. The method comprises the steps as follows: a focal distance range of an auxiliary down-looking camera is determined from a preselected focal distance range of the auxiliary down-looking camera according to predetermined spatial resolution of an photographic image and the photograph size and the pixel size of the auxiliary camera; according to the predetermined photograph size and pixel size of the auxiliary camera, installation inclined angle ranges or focal distance ranges of inclined auxiliary cameras from preselected inclined angle ranges; according to preset imaging rules of the auxiliary down-looking camera and four inclined auxiliary cameras, installation inclined angles and the focal distances of the inclined auxiliary cameras are determined; the focal distance of the auxiliary down-looking camera and the focal distances and the installation inclined angles of inclined auxiliary cameras of the aerial camera are configured correspondingly; and photographic images are shot and obtained by the aerial camera. According to the method, the images shot and obtained by the aerial camera can meet requirements for actual image applications.
Description
technical field [0001] The invention relates to the technical field of aerial photography, in particular to a method for optimizing the configuration of azimuth elements of an aerial photography instrument. Background technique [0002] The aerial camera includes a plurality of sub-cameras, and obtains photographic images of a target through the plurality of sub-cameras included. [0003] Generally, a downward-looking sub-camera and four tilting sub-cameras with a certain tilt angle are installed on the aerial camera. , a rear-view sub-camera, a left-view sub-camera, and a right-view sub-camera. Specifically, the four tilting sub-cameras have the same frame size and pixel size, the installation center points of the four tilting sub-cameras are located on the same plane, and the installation center points of the four tilting sub-cameras are connected in sequence to form a square, the following The optical axis of the viewing sub-camera is perpendicular to the plane where th...
