The invention relates to a vision-based driver assistance system and method. Embodiments provide line-based feature generation for vision-based driver assistance systems and methods. For one embodiment, a feature generator includes a circular buffer and a processor coupled to an image sensor. The circular buffer receives image data from the image sensor and stores N lines at a time of an image frame captured by the image sensor. The N lines of the image frame are less than all of the lines for the image frame. The processor receives the N lines from the circular buffer and stores one or more features generated from the N lines in a memory. Iterative blocks of N lines of image data are processed to complete processing of the full image frame, and multiple frames can be processed. The generated features are analyzed by a vision processor to identify, classify, and track objects for vision-based driver assistance and related vision-based assistance actions.
本公开涉及用于基于视觉的驾驶员辅助系统和方法。实施例提供用于基于视觉的驾驶员辅助系统和方法的基于行的特征生成。对于一个实施例,特征生成器包括循环缓冲器和耦合到图像传感器的处理器。所述循环缓冲器从所述图像传感器接收图像数据,并且在由所述图像传感器捕获图像帧时存储N行。所述图像帧的所述N行少于所述图像帧的所有行。所述处理器从所述循环缓冲器接收所述N行,并且将从所述N行生成的一个或多个特征存储在存储器中。处理N行图像数据的迭代块以完成完整图像帧的处理,并且可处理多个帧。生成的特征由视觉处理器分析以识别、分类和追踪目标,用于基于视觉的驾驶员辅助和相关基于视觉的辅助动作。
