Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings.
[0042] The invention is mainly based on a target detection module, a character extraction module and a judgment module.
[0043] Such as figure 2 As shown, the target detection module is composed of an image correction unit, a table format detection unit, a seal detection unit, and a text detection unit. First, the image correction unit uses Canny edge detection and LSD line detection to obtain the angle of image deflection and correct the image. Then use the corrected image as the input of the table format detection unit, apply the table format detection model, and obtain the ROI area; use the corrected image as the input of the seal detection unit, apply the seal detection model, and detect the red stamp and the MA stamp; according to the ROI Region offset gets the candidate region of text class information, takes the candidate region as the input of the text dete...
