A system for controlling vehicle operation comprises a controller and a command unit. The command unit is configured to generate a specific surface condition for a given path based on aggregated vehicle trajectories from a multitude of vehicles traveling on that path, including extracting the respective coordinates and trajectories of these multitude of vehicles over a predefined time period. The command unit is also configured to determine the respective lateral distances between these multitude of vehicles and a centerline on the given path. The given path is designated as an unpaved path if one or more predefined conditions based on these lateral distances are met. The unpaved path is defined by the absence of centerline markings.The control system is designed to retrieve the current surface condition and control the operation of the vehicle when the vehicle is traveling on the unpaved road.

This invention discloses a visual perception method and system for autonomous driving in mines based on YOLO real-time inference, relating to the field of environmental perception technology for autonomous driving in mines. The method employs an adaptive deconvolution deblurring algorithm based on inter-frame optical flow estimation to calculate the image plane displacement caused by low-frequency, high-amplitude vibrations from continuous image frames acquired by an onboard camera. Deconvolution operations are then performed on directional motion blur and edge texture degradation. The processed image frames are input into a YOLO real-time inference network with reconfigured anchor frame parameters. These anchor frame parameters are obtained by clustering the labeled dimensions of fallen rocks and eroded rock blocks from the slope in the mine. By performing optical flow deconvolution restoration operations on the blurred frames from the mine's bumpy terrain and reconfiguring the anchor frame parameters based on the clustering results of mine obstacle sizes, this invention enables the YOLO real-time inference network to maintain stable bounding box outputs and continuous trajectory markings for fallen rocks and eroded rock blocks under vibration conditions on unpaved roads.
