Abstract: An automotive imaging system may include image sensors that capture images from a vehicle's surroundings. The vehicle's chassis may partially obstruct the environment from the view of the image sensors. The imaging system may include processing circuitry that receives image frames from the image sensors and process the image frames to generate image data portraying blocked portions of the vehicle's surrounding environment. The processing circuitry may generate the image data during movement of the vehicle by combining time-delayed image data from the sensors with current image data from the sensors.
