摘要: An image collection system collects stereo image data comprising left image data and right image data of a particular scene. An estimator estimates a reference three dimensional image density rating for corresponding reference volumetric cell within the particular scene at a reference range from an imaging unit. An image density compensator compensates for the change in image density rating between the reference volumetric cell and an evaluated volumetric cell by using a compensated three dimensional image density rating based on a range or relative displacement between the reference volumetric cell and the evaluated volumetric cell. An obstacle detector identifies a presence or absence of an obstacle in a particular compensated volumetric cell in the particular scene if the particular compensated volumetric cell meets or exceeds a minimum three dimensional image density rating

摘要: A method and system for guiding a vehicle comprises a location determining receiver for collecting location data for the vehicle. A vision module collects vision data for the vehicle. A location quality estimator estimates the location quality data for the location data during an evaluation time window. A vision module estimates vision quality data for the vision data during the evaluation time window. A supervisor module selects at least one of a location data weight and a vision data weight based on the quality data.

摘要: A method and system for guiding a vehicle comprises a location determining receiver for collecting location data for the vehicle. A vision module collects vision data for the vehicle. A location quality estimator estimates the location quality data for the location data during an evaluation time window. A vision module estimates vision quality data for the vision data during the evaluation time window. A supervisor module selects a mixing ratio for the vision data and location data (or error signals associated therewith) based on the quality data.

摘要: A discriminator identifies windrow pixels associated with a windrow within a collected image. A definer defines a search space with respect to a vehicle. An evaluator determines respective spatial correlations between the defined search space and the windrow pixels for different angular displacements of the search space. An alignment detector or search engine determining a desired vehicular heading as a preferential angular displacement associated with a generally maximum spatial correlation between the defined search space and the windrow pixels. An offset calculator estimates an offset of the vehicle to a central point of the windrow or a depth axis to achieve the desired vehicle heading and desired position of the vehicle with respect to the windrow.
