Round seal curved text recognition method, device and system and readable storage medium

The invention discloses a circular seal curved text recognition method, device and system and a readable storage medium, and the method comprises the steps: obtaining a circular seal curved text image, and carrying out the detection of the circular seal curved text image through a text detection model, and obtaining a text character box coordinate and a character string region coordinate; according to the text character box coordinates and the character string area coordinates, processing each single character in the round seal curved text image to obtain a single-character positive-sequence spliced sub-image and a single-character reverse-sequence spliced sub-image; and according to the single-character positive-sequence spliced sub-graph and the single-character reverse-sequence spliced sub-graph, identifying text content in the round seal curved text image. According to the method, the circular seal curved text image is detected, the character level is switched into, meanwhile, the character string region
