    摘要: A motor vehicle vision system (10) including a stereo imaging system (11) and a data processing device (14) establishing an object detector (15) to detect an object and a tracker (16). The data processing device (14) calculates a size related value and a disparity related value for the object. An analysis section (20) performs an analysis on a group of at least five data points corresponding to different times, each data point includes a size related value and a disparity related value. The analysis uses predetermined regression function having at least one variable, and yields a best value for each variable corresponding to a best match of the regression function to the data points. The analysis section (20) calculates from a best value a systematic error in the disparity related values and/or in the size related values.

    摘要: A motor vehicle vision system (10) includes a pair of imaging devices (12a, 12b) forming a stereo imaging apparatus (11) and a data processing apparatus (14) for rectification of images captured by the stereo imaging apparatus (11), matching of rectified images, and to detect an object in the surrounding of the motor vehicle. The data processing device (14) performs, for image elements (43) of a rectified image from one imaging device, a search for a best-matching image element (44′) in the corresponding rectified image from the other imaging device. The search yielding vertical shift information from which a vertical shift from the image element (43) to the best-matching image element (44′) is derivable. The data processing device (14) calculates a pitch angle error and/or a roll angle error of or between the imaging devices (12a, 12b) from the vertical shift information.
