Pegmatite type lithium ore prospecting method based on multi-source remote sensing data

The invention relates to the field of mineral resource development, and particularly discloses a pegmatite type lithium ore prospecting method based on multi-source remote sensing data, which comprises the following steps: S1, acquiring geographic information image data and first remote sensing image data of a to-be-researched area, performing fragmentation preprocessing on the to-be-researched area according to the geographic information image data to obtain second remote sensing image data and third remote sensing data, and determining long-range mining area information; s2, based on second remote sensing image data of the to-be-studied distant view mining area, linear construction information is determined according to the second remote sensing image data; s3, third remote sensing image data and the like of the to-be-studied distant view mining area are obtained; through detailed analysis of remote sensing data, linear structure information and annular structure information are distinguished, a big data mo
