Quality verification and extraction method and device for physical and electric homologous electronic impression and medium

The invention discloses a quality verification and extraction method and device for an electronic impression of physical and electric homology and a storage medium. The quality verification and extraction method comprises the steps of seal target detection, seal target quality verification, electronic impression extraction and correction, electronic impression quality verification and electronic impression manufacturing. The input image enters a seal target quality verification link after being subjected to seal target detection, and when verification is not passed continuously for a preset number of times, the system sends a manual auditing request; extracting and correcting the seal target image passing manual checking to generate an electronic impression, entering an electronic impression quality checking link again, if checking is not passed for a preset number of times continuously, sending a manual checking request by the system, and if the electronic impression passing manual checking and correction is
