Abstract
This invention relates to the field of autonomous vehicle technology, specifically to a method and apparatus for estimating the pose of a vehicle's refueling cap. The method includes: acquiring at least one contour corresponding to the refueling cap based on an image of the refueling cap of a target vehicle; determining a preset contour template corresponding to the target vehicle based on the vehicle's model; determining a target contour corresponding to the target vehicle based on the distance between the moment features of each contour corresponding to the refueling cap and the moment features of the preset contour template; and determining the pose data of the refueling cap based on the mapping relationship between the image coordinates of the target contour and the world coordinates of the preset contour template.
