This disclosure provides systems, methods, and devices for vehicle driving assistance systems that support image processing for vehicular monitoring operations. In a first aspect, a method of image processing includes receiving image data from an image sensor comprising a red-clear-clear-green (RCCG) color filter, wherein the image data comprises a first channel corresponding to red, a second channel corresponding to clear, and a third channel corresponding to green, wherein the image data is in a logarithmic domain; and processing the image data by performing operations including linearization, tone mapping, demosaicing, and color mapping. Other aspects and features are also claimed and described.

Image sensor with red-clear-clear-green (RCCG) color filter array (CFA) for vehicle sensing applications

A vision system () for a motor vehicle with a stereo imaging apparatus () with imaging devices () adapted to capture images from a surrounding of the motor vehicle, and a processing device () adapted to process images captured by the imaging devices () and to detect objects, and track detected objects over several time frames, in the captured images. The processing device () is adapted to obtain an estimated value for the intrinsic yaw error of the imaging devices () by solving a set of equations, belonging to one particular detected object (), using a non-linear equation solver method, where each equation corresponds to one time frame and relates a frame time, a disparity value of the particular detected object, an intrinsic yaw error and a kinematic variable of the vehicle.

Vision system and method for a motor vehicle

A camera module () for a motor vehicle having a lens assembly (), a housing () with a back plate () and a lens holder (). The back plate () carries an image sensor () within the housing (). The lens holder () is mounted to the back plate () and holds the lens objective () such that the image sensor () is arranged in or close to an image plane (A) of the lens objective (). The back plate () is formed of at least one bi-material element () holding the image sensor (). The bi-material element () having at least two layers () of materials having significantly different thermal properties and being joined together such that the bi-material element () is adapted to bend with changing temperature.

Camera module for a motor vehicle

A camera module for a motor vehicle includes a lens objective, a lens holder holding said lens objective, and a back plate connected to said lens holder and holding an image sensor in or close to an image plane of the lens objective. The alignment of the lens holder relative to the back plate is fixed by a glue joint between the lens holder and the back plate.

Camera module for a motor vehicle and method of mounting a camera module

A motor vehicle camera module () having a lens assembly (), a housing () forming a front end () surrounding an opening (), an image sensor () carried by a back wall () within the housing () adjacent an image plane (A). The housing () having a lens holder () between the front end () and the back wall (). The camera module () has a tube () fixed to the lens holder () at the front end (). The tube () surrounds the opening () and extends from the opening () into the housing (). The lens assembly () is connected to a tube bottom end section by threads (). The thermal expansion coefficient of the tube () is higher than that of the lens holder (). The threads () extends over less than half of the axial length (h) of the lens assembly ().

A camera module for a motor vehicle having a lens objective, a lens holder holding said lens objective, and a back plate connected to said lens holder and holding an image sensor in or close to an image plane of the lens objective. The materials, shapes and/or relative positions of the components of the lens objective are designed to keep the image plane in or close to the sensitive plane of the image sensor over an operating temperature range of the camera module.
