Description

Multi-lens panoramic stereo camera

technical field

The utility model provides a 360-degree panoramic camera, in particular to a multi-lens panoramic stereo camera, which belongs to the technical field of photographic equipment.

Background technique

Due to the planar imaging method and narrow field of view of the traditional CCD area array single-lens camera, it is easily affected by occlusion, and sometimes cannot meet specific application requirements. A fisheye lens with a large field of view can overcome the problem of a narrow field of view to a certain extent. However, fisheye lenses will produce strong image distortion, which limits the application of panoramic cameras in many application fields.

The panoramic camera based on multi-lens can not only overcome the large deformation of the image caused by the end, but also has the advantages of imaging integration, 360-degree large field of view, rotation invariance, etc. gradually applied in the field.

At present, panoramic cameras are all in the form of a single panoramic image, which can only display flat two-dimensional images and information with a large field of view, and cannot realize the visualization of three-dimensional images and the acquisition of three-dimensional information, thus limiting the application of panoramic cameras in many fields and expansion, and greatly reduces the practicality of panoramic images.

The multi-lens panorama stereo camera provided by the utility model composes two images of the respective viewing angle ranges at the same time through a plurality of unit modules, and processes a group of multiple images obtained at the same time through a graphics processor, thereby obtaining two 360-degree images Panoramic image, using these two panoramic images with a certain overlapping range to generate a 360-degree panoramic stereoscopic image. The specific method is to divide the lenses distributed in the annular lens array into odd and even numbers, and all the lenses with odd numbers acquire a set of image data at the same time, and at the same time, the lenses with even numbers also acquire a set of data, through The high-precision image stitching technology stitches the images captured by odd-numbered and even-numbered lenses into two 360-degree panoramic images. Then, the two panoramic images are formed into a 360-degree panoramic stereoscopic image by using three-dimensional display methods such as red-green, polarized, and polarized. The utility model eliminates the complicated lens rotation mechanism, and has a simple structure and low manufacturing difficulty. By using the GPS module placed in the center of the camera, the three-dimensional coordinates of each lens center in space are constructed, and combined with the 360-degree panoramic stereoscopic image, it can be conveniently Quickly realize the 3D visualization within 360 degrees and the acquisition of spatial 3D information.
