Panoramic lens and pairing method thereof

Abstract

The invention discloses a panoramic lens and a pairing method thereof. The method comprises that to-be-measured camera modules shoot a first frame, and first present white balance parameters of the to-be-measured camera modules are obtained; according to the first present white balance parameters and a standard white balance parameter of a standard camera module, automatic white balance adjustmentis carried out on the to-be-measured camera modules; after automatic white balance adjustment, the to-be-measured camera modules shoot a second frame, and second present white balance parameters of the to-be-measured camera modules are obtained; and the to-be-measured camera modules whose difference in the second present white balance parameters is within a set range are selected and paired. According to the invention, automatic white balance adjustment is carried out on the to-be-measured camera modules, gains of different channels are changed so that the white balance parameters of the modules approach the standard white balance parameter more, color consistency of the modules is restored, the modules whose second present white balance parameters are consistent or similar are selected and paired to form a panoramic lens, and it is ensured that the brightness of two modules is consistent or has little difference.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a panoramic lens pairing method and the panoramic lens. Background technique [0002] At present, there are many schemes for realizing 360° panoramic camera panoramic shooting, one of which is composed of two fisheye camera modules back to back. However, due to the differences between the modules, the brightness and color of the two cameras will be inconsistent after pairing and assembly. The existing pairing method needs to find modules with similar brightness, R / G, and B / G. Because the three conditions are considered at the same time, the selection is relatively difficult, and it may not be possible to match all the modules one by one. [0003] Therefore, how to realize 360° panorama lens pairing simply and efficiently is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the purpose of the present ...
