Problems solved by technology
[0002] In related technologies, traditional regional geological mapping and mineral mapping mainly rely on the subjective judgment of the staff to determine the mapping unit, resulting in the need to complete a large number of physical workloads of routes and profiles in the field survey work, requiring extremely high manpower, financial and material resources cost
At least to solve the above problems, most of the machine learning-based mapping methods in related technologies are aimed at specific data types and rely on high-quality data sets. Working in blank areas or areas with insufficient data will face the difficulty of lacking basic geological support

An embodiment of the present application provides a method, device and storage medium for lithology mapping, the method comprising: inputting the acquired lithology characteristic data of the target mapping area into the i-th mapping model to obtain the i-th mapping result, Wherein, the i-th mapping result includes the average probability value in the sub-area where each mapping point is located, and the sub-area is obtained after gridding the target mapping area; determine the i-th mapping result When the preset condition is met, select the target mapping sub-area from the multiple sub-areas obtained by dividing the target mapping area; when the mapping result of the target mapping sub-area does not meet the termination condition, according to Label data to adjust the parameters of the i-th mapping model to obtain the i+1-th mapping model; repeat the above process until the mapping result meets the termination condition, and output the final mapping result, which can realize the existing Carry out mapping for the target mapping area where data is lacking.
Description
technical field [0001] The embodiments of the present application relate to the field of geographic mapping, and in particular to a method, device and storage medium for lithology mapping. Background technique [0002] In related technologies, traditional regional geological mapping and mineral mapping mainly rely on the subjective judgment of the staff to determine the mapping unit, resulting in the need to complete a large number of physical workloads of routes and profiles in the field survey work, requiring extremely high manpower, financial and material resources cost. At least in order to solve the above problems, most of the mapping methods based on machine learning in related technologies are aimed at specific types of data and rely on high-quality data sets. Working in blank areas or areas with insufficient data will face the difficulty of lacking basic geological support . [0003] Therefore, how to map the target mapping area where the existing data is lacking h...
