Yes, self-driving cars sometimes use OpenCV as part of their vision software, especially during prototyping or for simpler tasks. OpenCV is an open-source library that provides tools for image processing, object detection, and computer vision algorithms.
In production systems, more specialized frameworks like TensorFlow or PyTorch are often used for deep learning tasks, such as detecting pedestrians, lane markings, or traffic signs. These frameworks offer more advanced capabilities for real-time decision-making.
However, OpenCV remains valuable for preprocessing tasks, such as image filtering, edge detection, or camera calibration, which are essential steps in many vision pipelines.
