Automatic logging method, system and device for drilling core RQD and medium

The invention provides a drilling core RQD automatic logging method, system and device and a medium, and belongs to the field of underground engineering drilling engineering informatization. The system comprises an image acquisition module, an image preprocessing module, an RQD calculation module and a catalog module. According to the method, the rock core box images are collected in a standardized and batched mode, distortion correction is conducted on the rock core box images through a semantic segmentation network and projection transformation, then rock core blocks of 10 cm or above are marked through semantic segmentation, and RQD is calculated after recognition results are ranked; on-site collected images are uploaded to a cloud end, rock core box image correction and an RQD calculation algorithm are integrated on the cloud end, image data storage, RQD calculation and RQD database logging are carried out on the cloud end, and data digitization and standardization backup is achieved.
