A method of checking wing position in a CMS includes performing a calibration of a wing position supporting a camera relative to a vehicle to provide a desired field of view by capturing multiple images at different lighting conditions, extracting and storing a reference feature from each of the multiple images, triggering a wing position check, capturing a current image from the camera having a current position of the reference feature; sensing a current lighting condition at which the current image is captured, determining that one of the different lighting conditions is more similar to the current lighting condition, comparing the current position of the reference feature to the stored reference feature from the one of the multiple images generated under the one of the different lighting conditions, and outputting a result of the wing position check if a difference from the comparing step exceeds a threshold value.

Camera monitor system with camera wing unfolding status detection based upon image processing

A method for determining a trailer detection parameter of a trailer including receiving an image from at least one camera at a controller. The at least one camera defines a field of view including at least a portion of a vehicle trailer. The method determines a trailer angle of the vehicle trailer relative to a tractor, identifies at least one feature in an image of the trailer, determines a two-dimensional distance from the at least one feature to a predefined position on the image, and converts the two-dimensional distance to a three-dimensional distance based at least in part on the determined angle. The three-dimensional distance is a trailer detection parameter of the trailer.

Image based trailer wheelbase determination

A method for automatically panning a view for a commercial vehicle includes determining a plurality of estimated trailer angles. Each estimated trailer angle is determined using a distinct estimation method, and method assigns a confidence value to each estimated trailer angle in the plurality of estimated trailer angles. The method determines a weighted sum of the plurality of estimate trailer angles, and automatically pans the view based at least in part on the weighted sum and a current vehicle operation.

Auto panning camera mirror system including weighted trailer angle estimation

A method for automatically panning a view for a commercial vehicle includes receiving a video feed from at least one camera defining a field of view. A plurality of objects in the video feed, includes at least one wheel and at least one line, are identified. A path of each object in the plurality of objects is tracked through an image plane of the video feed. A trailer angle corresponding to each path is identified, the identified trailer angle is associated with the corresponding path, thereby generating a plurality of trailer angle measurements. The plurality of paths are down selected to a single path and identifying a single trailer angle measurement corresponding to the single path.
