摘要： A slope detection system (10, 19, 185C) for a vehicle (100) is provided. The system has a processor (10, 19) that receives, from one or more sensors (185C) arranged to capture data in respect of terrain ahead of the vehicle, terrain information indicative of the topography of an area extending ahead of the vehicle (100). The processor (10, 19), in dependence upon a predicted path of the vehicle (100) over the terrain extending ahead of the vehicle (100), generates, for the predicted path of the vehicle (100), information indicative of an angle of slope of the predicted path, being the slope of the predicted path along a direction of travel of the vehicle (100).

摘要： A crest detection system (10, 19, 185C) for a vehicle (100), the system comprising a processing means (10, 19) arranged to receive, from terrain data capture means (185C) arranged to capture data in respect of terrain ahead of the vehicle by means of one or more sensors, terrain information indicative of the topography of an area extending ahead of the vehicle (100), wherein the processing means (10, 19) is configured to, in dependence upon a predicted path of the vehicle (100) over said terrain extending ahead of the vehicle (100), determine that a crest exists in the predicted path in dependence at least in part on the detection of a discontinuity in terrain along the predicted path ahead of the vehicle (100) based on the terrain information, and information in respect of slope of terrain before the discontinuity.

摘要： Embodiments of the present invention provide systems and methods for use in a non-lead vehicle in a convoy, particularly an off-road convoy. The system comprises an image handling module adapted to obtain non-lead image data of the scene in the vicinity of the non-lead vehicle; a communications module adapted to receive data from a preceding vehicle in the convoy, the data comprising at least lead image data of the scene in the vicinity of the preceding vehicle; a processing module adapted to: obtain pose data of the preceding vehicle and a sparse map, both derived from the lead image data, wherein the sparse map comprises coordinates of a set of identifying features in the scene, and derive pose data of the non-lead vehicle relative to the preceding vehicle from the non-lead image data and the sparse map via visual odometry.

摘要： Embodiments of the present invention relate to a control system for a vehicle, the control system comprising at least one controller and being configured to: obtain image data relating to terrain to be traversed by the vehicle, and for each of a plurality of sub-regions of the image data: determine probability data relating to whether the respective sub-region relates to a path region or a non-path region of the terrain; and determine a cost for the vehicle to traverse a portion of the terrain to which the sub-region relates depending on the probability data meeting one or more path probability criteria indicating that the sub-region relates to the path region, one or more non-path probability criteria indicating that the sub-region relates to the non-path region or neither the path probability criteria nor the non-path probability criteria; and determining a vehicle path in dependence on the determined costs.
