The application belongs to the technical field of rock painting identification, and particularly relates to a rock painting identification method, comprising the following steps: obtaining rock painting incision depth information; judging the positive and negative values of the incision depth information based on an incision depth model; if the value is positive, marking the incision depth information as invalid incision; if the value is negative, marking the incision depth information as valid incision; obtaining rock painting incision position information; based on a rock painting incision position model, pre-processing the valid incision, and outputting a rock painting basic sample; based on a rock painting information library, comparing the similarity of the rock painting basic sample, and outputting a rock painting number. The incisions on the rock painting at the damaged part are marked as valid and invalid, then the valid incisions are connected with the incisions that are not damaged and accurate, and then the incisions are compared with the information of the previous general survey, so that the problems that professional personnel are difficult to identify due to long interval time, sand covering, plant covering, human damage and the like, and the problems that search cannot be found or too many similar search results exist are solved.
