Problems solved by technology

[0003] The current oblique photography camera is generally a five-camera structure, including four oblique cameras and a middle front camera. The defect of this technology is that it can only collect data from five viewing angles. To increase the collection angle, more cameras need to be added. camera, which greatly increases the volume weight of the device and increases the cost

Abstract

The invention discloses a tilting photography device and a method for adjusting an angle of view, including the tilting photography device and the method for adjusting an angle of view. The tilting photography device includes a casing, a fixing piece, four cameras arranged side by side, and a rotating assembly; Rotate to the horizontal or vertical direction, and initially set each camera to be perpendicular to the direction of the arrangement direction, so that the shooting direction is parallel to the midline of the 4 cameras, and rotate the camera so that the two cameras in the middle rotate outwards at an angle of β, and the two cameras on the outer sides face outwards The angle of rotation is θ. After the camera is rotated, the boundaries of the fields of view of the two middle cameras are parallel to each other; this device and method can increase the shooting area on the basis of traditional camera shooting, precisely adjust the rotation angle of the camera, and form a full view of multiple angles. Azimuth shooting.

Description

technical field [0001] The present invention relates to the technical field, in particular, to an oblique photographing device and a method for adjusting an angle of view. Background technique [0002] Oblique photography technology is a high-tech developed in the field of international photogrammetry in the past ten years. This technology obtains rich high-resolution textures of building top surfaces and side views by synchronously collecting images from different perspectives. It can not only truly reflect the situation of ground objects, obtain object texture information with high precision, but also generate a real 3D city model through advanced positioning, fusion, modeling and other technologies. [0003] The current oblique photography camera generally has a five-camera structure, including four oblique cameras and a central front camera. The defect of this technology is that it can only collect data from five viewing angles. To increase the collection angle, more cam...
