Title: Vehicle Guidance Based on Soil Trafficability Via a UAV Sensor
Description: As described below, the use of UAV collected data and images to determine the quality of
various terrain characteristics throughout a worksite and the generation of vehicle path plans and guidance based on the UAV collected data, is disclosed.
A UAV (Unmanned Aerial Vehicle) contains one or more sensors and collects data, such as one or more thermal images of a worksite (e.g., an agricultural, forestry or construction worksite). The thermal images are used to determine trafficability within the worksite based on soil temperature (e.g., frozen, not frozen) and/or soil moisture (e.g., saturation level, soil type). The UAV soil trafficability data is used to guide a vehicle (e.g., an off‐road vehicle or work vehicle) from one place to another without the vehicle getting stuck by selecting a path plan which only traverses points in the worksite where the vehicle has a low probability of getting stuck. For example, a path plan may be generated based on a moisture characteristic such as unsaturated or not covered by standing water. In another example a path plan may be generated based on a soil temperature characteristic such as frozen.
A UAV may also fly ahead of a vehicle to verify trafficability as it is following the planned path.
