2 Cheap Cameras Can Provide LiDAR-like Object Detection

For most self-driving cars, the data captured by cameras or sensors is analyzed using convolutional neural networks – a kind of machine learning that identifies images by applying filters that recognize patterns associated with them. These convolutional neural networks have been shown to be very good at identifying objects in standard color photographs, but they can distort the 3D information if it’s represented from the front. So when Wang and colleagues switched the representation from a frontal perspective to a point cloud observed from a bird’s-eye view, the accuracy more than tripled.
