Problems solved by technology

[0003] Among them, the fisheye lens and the reflective panoramic camera have large image distortion and limited resolution, which limits their application in the field of panoramic stereoscopic imaging.
In the existing multi-camera panoramic cameras, the cameras are mostly spherically distributed, with large volume and complex structure; the overlapping fields of view of adjacent cameras are used to realize panoramic stereoscopic imaging, and the optical axes of adjacent cameras are not parallel and the baseline is short, which is not conducive to stereoscopic imaging

Embodiment 1

[0023] Such as figure 1 As shown, it is a schematic diagram of the three-dimensional structure of the panoramic stereo imaging device according to Embodiment 1 of the present invention. The housing 5 has a hexagonal flat structure, and has 12 C-shaped side walls 3 and 12 D-shaped side walls 4 on its surface, and each side wall is provided with a lens hole (not shown); the camera system includes 12 Group A camera 1 and 12 group B cameras 2; all cameras are of the same model, and the imaging field of view is greater than or equal to 60°×60°; the elevation angle of group A camera 1 is 0°, distributed on the same plane, installed and fixed on on the C-shaped side wall 3 with an elevation angle of 90°; the elevation angles of group B cameras 2 are all 60°, which are also distributed on the same plane, and are installed and fixed on the D-shaped side wall 4 with an inclination angle of 30°; group A cameras The planes where the cameras of group 1 and group B are located are parallel...

Embodiment 2

[0026] Such as Figure 4 As shown, it is a schematic diagram of the three-dimensional structure of the panoramic stereoscopic imaging device in Embodiment 2 of the present invention. The difference from Embodiment 1 is that all the cameras in Embodiment 2 are on the same plane, that is, the plane where Group A camera 1 and Group B camera 2 are located. Coincidentally, and the shell structure has been changed accordingly.

Embodiment 3

[0028] Such as Figure 5 As shown, it is a schematic diagram of the three-dimensional structure of the panoramic stereoscopic imaging device in Embodiment 3 of the present invention. The difference from Embodiment 2 is that in Embodiment 3, all the B-group cameras 2 are translated as shown in the figure and distributed on two concentric circles. At the same time, the shell structure has been changed accordingly.

[0029] In the above embodiment, 24 cameras form 12 stereo vision units, and the elevation angles of the two groups of cameras are 0° and 60° respectively, and each group has 12 cameras. In order to cope with more demands: 12 cameras of the same type with a depression angle of 60° can be added to realize stereoscopic imaging of a spherical 360°×360° field of view; the number of groups and the number of cameras can be changed according to the principle of field of view division to complete Stereoscopic imaging of arbitrary continuous spherical space. The above design...

Abstract

The invention discloses a plane-distributed multi-camera panorama stereoscopic imaging device, which comprises several cameras of the same type and a fixed casing. Based on the field of view of the camera, the spherical surface from the 0° latitude line to the pole is divided into several latitude intervals; each latitude interval is divided into several longitude and latitude intervals according to the longitude, and each longitude and latitude interval is viewed by a stereo vision unit Covering; each stereo vision unit is composed of two cameras with parallel optical axes; the stereo vision units are interspersed with each other according to the polygonal structure, so that the stereo vision unit obtains a longer baseline; the shell is in a flat structure, with all the cameras The outline formed by the fixed surface is the shape, and ensures that the field of view of the camera is not blocked. The device has the advantages of simple structure, high resolution and long baseline, and can realize stereoscopic imaging in hemispheric space.

Description

technical field [0001] The invention relates to the technical field of panoramic stereo imaging, in particular to a multi-camera panoramic stereo imaging device distributed in a plane. Background technique [0002] At present, panoramic stereoscopic imaging devices mainly include fisheye lenses, catadioptric panoramic cameras and multi-camera panoramic cameras. [0003] Among them, fisheye lenses and catadioptric panoramic cameras have large image distortion and limited resolution, which limits their application in the field of panoramic stereoscopic imaging. In the existing multi-camera panoramic cameras, the cameras are mostly spherically distributed, with large volume and complex structure; the overlapping fields of view of adjacent cameras are used to realize panoramic stereoscopic imaging, and the optical axes of adjacent cameras are not parallel and the baseline is short, which is not conducive to stereoscopic imaging .
