Title:
EXPOSURE PARAMETER ACQUISITION METHOD FOR PANORAMIC IMAGE
Document Type and Number:
WIPO Patent Application WO/2021/012854
Kind Code:
A1
Abstract:
Disclosed is an exposure parameter acquisition method for a panoramic image, the method comprising the following steps: connecting a lens module to a rotation apparatus, setting parameters, i.e. a rotation angle and the number of rotations, of the rotation apparatus, and the rotation apparatus driving, according to the set parameters, the lens module to rotate to different angle positions; each time a lens of the lens module rotates to an angle position, carrying out light metering on a current field of view to acquire an exposure parameter; and after the rotation apparatus drives the lens module to rotate to the last light metering angle, fusing a plurality of sets of exposure parameters acquired by the lens module at all angle positions, so as to obtain a fused exposure parameter, wherein the fused exposure parameter is a uniform exposure parameter during the photographing of a panoramic image. By means of the exposure parameter acquisition method of the present invention, panoramic photographing under a complex light environment can be realized.
