Abstract

The invention discloses a mobile phone backlight module lighting detection ROI segmentation method. The mobile phone backlight module lighting detection ROI segmentation method comprises the followingsteps of 1 carrying out the global threshold analysis on a to-be-detected picture to obtain a segment region; 2 carrying out the 8-neighborhood connected region analysis on the SegmentRegion obtainedfrom the threshold analysis, and finding and marking the connected region in the image; 3 selecting region according to area size, removing interference, and performing region filling operation on that selected region to obtain an integrated region; 4 carrying out the morphological opening operation on the intact area to remove burr points to obtain the module pattern area. The mobile phone backlight module lighting detection ROI segmentation method can realize the segmentation of the module pattern picture to be detected from the collected entire mobile phone module image.

Description

technical field [0001] The invention relates to the field of machine vision detection, in particular to a ROI segmentation method for mobile phone backlight module lighting detection. Background technique [0002] Machine vision detection technology mainly simulates the visual function of the human eye through computer cooperation with industrial cameras and lenses, processes and understands images of objective things and extracts useful information from them, and is finally used for actual detection and classification. [0003] With the development of the economy, mobile phones have become an indispensable item for everyone all over the world. In mobile phones with LCD screens, the display screen is an important component. A complete display screen structure is: front frame, horizontal polarizer, color filter, glass substrate, liquid crystal, thin film transistor glass substrate, vertical polarizer, The driver IC is composed of printed circuit board, diffusion plate, plast...
