Embodiment Construction

[0038] Due to the change of ambient light during the shooting process and the unreasonable adjustment of the image brightness in the image preprocessing process, it will cause the horizontal stripes phenomenon of the 3D reconstructed human body, making the reconstructed image discontinuous. In view of this, the purpose of the present invention is to weaken or eliminate these horizontal stripes, so that the reconstruction results are continuous and can transition smoothly.

[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative e...

Abstract

The invention discloses a method and device for adjusting the exposure of a sequence diagram, comprising: Step S1: adjusting the exposure of the first image in the sequence diagram, and decoding the first image as a reference image; Step S2: The unprocessed image adjacent to the reference image sequence is used as the current adjusted image, and multiple exposures are selected within the second preset range to obtain multiple images corresponding to the exposure; Step S3: After decoding the multiple images, they are respectively compared with Carry out homogeneous area marking on the reference image, determine the optimal exposure of the current adjusted image, and use the optimal exposure to adjust the current adjusted image; step S4: determine whether the sequence value of the current adjusted image is greater than the sequence length of the sequence diagram, If not, use the adjusted image as a reference image, and return to step S2; if yes, end the process. The invention can make the brightness and darkness of the sequence images consistent, the reconstructed images are continuous, and the image consistency improvement effect is good.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a method and device for adjusting the exposure of sequence diagrams. Background technique [0002] Color tomographic image preprocessing is an important step affecting 3D reconstruction. In order to preserve the scene information and color information of the tomographic image, the shooting format is RAW. In the later stage, the RAW file is decoded to generate a format that can be browsed by commonly used image viewing software. The decoded color image sequence cannot guarantee the consistency of sequence image brightness due to changes in ambient light. The image after 3D reconstruction can be sliced ​​and viewed in any direction. Since the inconsistency of light and shade will affect the reconstruction effect, the reconstructed image is discontinuous and horizontal stripes appear. [0003] The current solution is mainly to adjust the brightness value ...
