A Method for Acquiring Calibration Parameters

Abstract

An embodiment of the present invention provides a method for obtaining correction parameters, the method comprising: obtaining the first images when the lenses in the lens group to be corrected respectively shoot the target paper, and the lenses in the lens group to be corrected are: all the lenses in the multi-lens device There are overlapped lenses corresponding to the focal length segment, the size of the pixels in each first image is the same, the focal length and object distance are the same when the lens in the lens group to be corrected obtains the first image, and the target paper is provided with the first calibration point; for the lens to be corrected Correcting the first image corresponding to each lens in the lens group, determining the coordinate position of the imaging point of the first marking point in the first image; based on the coordinate position of the imaging point of the first marking point in each first image, calculating each The translation correction parameters of the first lens relative to the second lens. In order to obtain correction parameters for correcting images captured by different lenses in the above-mentioned multi-lens device.

Description

technical field [0001] The invention relates to the technical field of parameter calibration, in particular to a calibration parameter acquisition method, device and electronic equipment. Background technique [0002] At present, in order to expand the range of focal lengths supported by image acquisition devices such as cameras and cameras, most of them use multi-lens settings to use the set lenses that support different focal lengths to capture images of different focal lengths, and realize the image acquisition equipment. Extension of the range of supported focal lengths. Wherein, the above-mentioned image acquisition device provided with multiple lenses may be referred to as a multi-lens device. [0003] During the lens installation process of the above-mentioned multi-lens device, it is unavoidable that different lenses have different shooting angles. Due to the differences in shooting angles between different lenses in a multi-lens device, when the multi-lens device ...

AI Technical Summary

Problems solved by technology

[0003] In the lens installation process of the above-mentioned multi-lens equipment, it is inevitable that there will be differences in shooting angles between different lenses

Due to the differences in shooting angles between different lenses in a multi-lens device, when the multi-lens device switches lenses to capture images for users to view, there are differences between the images captured by the different lenses, for example: an object in the scene is imaged In the upper left corner of the image captured by the lens before switching, the subject is imaged in the lower right corner of the image captured by the lens after switching, and the difference between the images will bring a bad experience to the user
