A vehicle is equipped with a camera (which may be a stereoscopic camera) and a computer for processing the image data acquired by the camera. The image acquired by the camera is processed by the computer, and features are extracted therefrom. The features are further processed by various techniques such as object detection/segmentation and object tracking/classification. The acquired images are sometimes contaminated by optical occlusions such as raindrops, stone-chippings and dirt on the windshield. In such a case, the occluded parts of the image are reconstructed by optical flow estimation or stereo disparity estimation. The fully reconstructed image is then used for intended applications.

A hybrid digital pulse width modulator with delay chain optimization function belongs to the technical field of power electronics. A coarse adjustment module uses a comparator to realize the conversion between the comparison state and the clock state. In the comparison state, the counting signal and the high-order signal of the counting clock signal are compared. In the clock state, the counting clock signal is corrected and used as the timing control of the calibration unit in the fine adjustment module. A fine adjustment module includes a calibration unit, a calibration output unit, a decoder, a delay chain and a multiplexer, wherein, the calibration unit generates a calibration code according to the delay signal fed back by the delay chain as a calibration signal, the calibration code is decoded by the decoder, the path of the delay chain is controlled, and finally, the multiplexer selects the corresponding output of the delay chain as an output signal of the fine-tuning module according to the low-order signal. The digital logic module generates a pulse width modulated signal according to the output signals of the coarse modulation module and the fine modulation module. The invention optimizes the delay time and can obtain the pulse width modulated signal with higher accuracy.
