Abstract: A dimension calculation system in a host vehicle for dynamically calculating a vehicle dimension using solar shadow information is disclosed. The system is configured to: calculate solar position and an expected vehicle shadow based on geocode location, time and vehicle dynamics; detect an actual vehicle shadow in an image from a vehicle camera; compare the actual vehicle shadow to an expected vehicle shadow; determine a dimension profile and max height point for a vehicle plus vehicle cargo based on a comparison of the actual vehicle shadow to the expected vehicle shadow; calculate a confidence level for the dimension profile and max height point for the vehicle plus cargo; and use the dimension profile and max height point to provide one or more dimension notifications when the confidence level for the dimension profile and max height point for the vehicle plus cargo are above a first threshold level.

Abstract: In exemplary embodiments, methods and systems are provided that include or utilize one or more automotive equipped cameras and a processor. The one or more automotive equipped cameras are configured to be onboard a vehicle and to obtain camera images during operation of the vehicle, the camera images including a view of one or more wheels of the vehicle. The processor is coupled to the one or more cameras, and is configured to at least facilitate: processing the camera images; and determining one or more states of the one or more wheels, including an alignment thereof, a health thereof, or both, based on the processing of the camera images.

Abstract: Systems and methods enhanced image processing with dynamic pixel density restoration and clarity retrieval for scaled imagery including a camera configured to capture an image having a first resolution and a first image clarity, an image processor for receiving the image, scaling the image to a second resolution to generate a scaled image resulting in the scaled image having a second image clarity, the image processor being further operative to adjust a sharpness of the scaled image to generate an adjusted scaled image such that the adjusted scaled image has the first image clarity, a driving assistance processor for generating a motion path in response to the adjusted scaled image, and a vehicle controller for controlling a vehicle in response to the motion path.
