Abstract

The invention provides an image data view angle correction method and device, equipment and a storage medium, and the method comprises the steps: obtaining a feature image; filtering the feature image, and removing a high-frequency component in the feature image to obtain a visual angle deviation component graph; calculating the normalized view angle deviation component graph based on a preset fitting formula to obtain an omnidirectional view angle weight graph; and performing weighted correction on the feature image based on the omni-directional view angle weight map. By correcting the visual angle deviation of the image data, the accuracy of the data is ensured, and the correction accuracy is prevented from being influenced.

Description

technical field [0001] The present application relates to the technical field of image data, and in particular, to a method, apparatus, device, and storage medium for viewing angle correction of image data. Background technique [0002] With the rapid development of display technology, more and more large-screen displays are widely used. Among them, the application of LED displays is also gradually diversified. The existing large-screen LED screens are generally composed of several cabinets. There are differences in the luminous characteristics, viewing angle characteristics, and arrangement of the LED lamps in the cabinet. The brightness and chromaticity uniformity correction has become a necessary link for the LED display to leave the factory. [0003] In the prior art, the brightness and chromaticity correction uses an industrial camera to take pictures to collect the brightness and chromaticity data, but there will be a viewing angle deviation during the acquisition proc...
