Problems solved by technology

[0002] At present, automatic optical inspection technology can be used to detect whether there is a defect in the object, but in practice, it is found that before performing a certain defect detection on the object, it is necessary to analyze the collected image data of different light sources separately, and after a large number of experiments, to determine It takes a long time to highlight defective light sources

Embodiment approach

[0092] As an optional implementation manner, the light source determination device may further include:

[0093] The analysis module is used for the generation module 202 to perform hyperspectral image analysis on the pseudo hyperspectral image cube according to a preset analysis algorithm after generating the pseudo hyperspectral image cube according to the plurality of grayscale images to obtain analysis data ;

[0094] The saving module is used for saving the analysis data into the database.

[0095] Wherein, the preset analysis algorithm includes any one of a band selection algorithm and an orthogonal subspace projection algorithm. The band selection algorithm is to select the main band subset from all the bands of the hyperspectral image, which can not only greatly reduce the data dimension of the hyperspectral image, but also retain useful information relatively completely. The orthogonal subspace projection algorithm is that projection is a linear transformation that ...

Abstract

The invention relates to an image processing technology, and provides a light source determination method and device, electronic equipment and a storage medium. The method comprises the steps that a plurality of gray level images of an object carrying a target defect are obtained, and different gray level images correspond to different light sources; generating a pseudo hyperspectral image cube according to the plurality of grayscale images; determining defect information and spectral wavelength corresponding to the target defect from the pseudo hyperspectral image cube; generating a spectral characteristic curve according to the defect information and the spectral wavelength; and determining a target light source from the spectral characteristic curve according to a hyperspectral image analysis algorithm. The light source selection efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a method, an apparatus, an electronic device, and a storage medium for determining a light source. Background technique [0002] At present, automatic optical inspection technology can be used to detect whether objects have defects. However, in practice, it is found that before detecting certain defects on objects, it is necessary to analyze the collected image data of different light sources separately. After a large number of experiments, to determine It takes a long time to highlight defective light sources. [0003] Therefore, how to select the light source is a technical problem that needs to be solved urgently. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a light source determination method, device, electronic device and storage medium, which can improve the selection efficiency of light sources. [0005] A f...
