Embodiment 1
[0053] This embodiment provides a shooting method for aerial oblique photography of matrix images, such as figure 1 As shown in -2, there are twelve shooting planes in the mounting compartment, and the shooting planes are arranged in an array of three rows and four columns or four rows and three columns; the shooting methods include:
[0054] S1. Airline calculation: Determine the height and accuracy of shooting according to the area of the shooting area, and further determine the focal length of the tilting camera.
[0055] S2. First determine the tilt angle of the outer tilt camera corresponding to the edge shooting plane, and calculate the tilt angle of the remaining tilt camera according to the tilt angle of the outer tilt camera; wherein, the process of calculating the tilt angle of the remaining shooting plane is: the outermost tilt The angle between the optical axis of the camera and the vertical plane where the flight line is located is α, and the angle between adjac...

The invention provides an oblique aerial photography method for taking a matrix image. The photography method comprises the following steps: S1, calculating an airway: determining the photographing height and the photographing precision according to the area of a zone to be photographed, and further determining the focal length of oblique cameras; S2, determining the inclination angles of the oblique cameras: determining the inclination angle of the outside oblique camera corresponding to an edge photographing plane, and calculating the inclination angles of the remaining oblique cameras according to the inclination angle of the outside oblique camera; and S3, completing the photographing: determining the number of the cameras and the layout of the cameras according to different photographing heights, and controlling the oblique cameras to photograph by a control module in order to complete the obtaining of the matrix image at the same photographing position. The photography method hasthe advantages of simplicity, reliability, high photographing precision, low requirements for the oblique cameras, and realization of multi-angle free photographing, and can completely reproduce thetrue proportional relationship of all objects in the working zone in order to make a later model clear and accurate.
Description
technical field [0001] The invention relates to a shooting method for aerial oblique photography for shooting matrix images. Background technique [0002] The aerial panoramic oblique photography device belongs to the technical category of aerial photogrammetry and aerial oblique photography. Aerial photogrammetry is based on aerial photographing images and using photogrammetry technology to produce various surveying and mapping products, including digital ground models, orthophoto maps and line-drawn maps. Aerial oblique photogrammetry is to obtain the side texture of ground objects by shooting oblique images, and then establish a real 3D model of the city through photogrammetry technology. [0003] Aerial oblique photography is a breakthrough of traditional aerial photogrammetry. Through the combination of cameras with different perspectives, it can shoot natural objects and artificial buildings on the ground. Existing aerial oblique photography devices generally adopt t...
