Geological exploration drilled hole imaging system and method

The invention provides a geological exploration drilled hole imaging system. The geological exploration drilled hole imaging system comprises a drilled hole wall shooting instrument and an imaging analysis device. In the operating process, the drilled hole wall shooting instrument is lifted up from the bottom of a drilled hole, a posture sensing module collects the current positional information of the drilled hole wall shooting instrument, and a high-definition camera shoots the inner wall of the drilled hole. A geological exploration drilled hole imaging method of the system includes the steps of lifting up the drilled hole wall shooting instrument, shooting the inner wall of the drilled hole with the drilled hole wall shooting instrument, generating a drilled hole three-dimensional numerical model, analyzing the drilled hole three-dimensional numerical model and the like. By adoption of the system, coring can be avoided in the drilling process, and the recovery rate can reach 100%,which is far superior to
