Embodiment 1
[0025] Example 1: Please refer to figure 1 As shown, the present invention discloses a method for electronically intelligent filling of vouchers, comprising the following steps:
[0026] S1. Collect the voucher image and identify the voucher information: convert the voucher image into voucher information through digital image recognition, and the voucher image includes the voucher name and the recorded items on the voucher;
[0027] S2. Voucher image recognition processing: perform digital image acquisition, image preprocessing and recognition processing operations on the recognized image in step S1. Digital image acquisition is performed through a mobile terminal with a built-in camera. Image preprocessing uses Hough transform to correct perspective distortion The algorithm performs image recognition processing on the image;
[0028] S3. Voucher image information is used to classify vouchers: according to the image voucher information matching rules obtained in step S2, the ...
