Radioactive source searching method and system based on robot platform

The invention discloses a radioactive source searching method and system based on a robot platform, and the system comprises a plurality of bearing platforms and a source searching host, and each bearing platform is in communication connection with the source searching host. Each bearing platform bears an azimuth measuring device and is used for acquiring azimuth data and radiation dose rate data of the radioactive source and uploading the azimuth data and the radiation dose rate data to the source searching host; the bearing platform also bears a GPS positioning device which is used for acquiring position data of the bearing platform and uploading the position data to the source searching host; and the source searching host acquires the position information of the radioactive source according to the radioactive source azimuth data and the radiation dose rate data uploaded by each bearing platform and in combination with the position data of each bearing platform.
