Abstract
The invention discloses a lightweight general mileage metering optimization method for an underground tunnel environment. The lightweight general mileage metering optimization method comprises the following steps: S1, a real-time positioning stage; s2, a mileage optimization stage. Compared with the existing method, the method has the advantages that the mileage optimization module is more suitable for being deployed in an underground environment and other environments with limited positioning conditions, training data acquisition is more flexible, the model parameter quantity is small, the reasoning speed is high, and the requirements of real-time performance and deployment feasibility are better met. The method can be combined with various traditional positioning methods, is particularly suitable for a lightweight mileage calculation method, and can effectively optimize the mileage metering result of the traditional positioning method.
