Abstract: Rock and mineral appraisal is an important part of geological research. Traditional methods of rock ore appraisal are generally realized with the help of mineral appraisal manuals, which are inefficient and prone to errors. The rock and mineral appraisal auxiliary recognition system combines traditional methods with computer systems and enters optical properties of transparent minerals observed into the system. The system helps simplify the procedures and improve the accuracy of the appraisal results, which is of great significance to the accurate appraisal of rocks and minerals.
