According to foreign media reports, terranet, a Swedish technology company, will show voxelflow, a 3D motion sensing technology, at CES 2020. Compared with lidar, voxelflow can detect and classify objects more accurately and quickly. In April last year, CEO Elon Musk said that "lidar is futile and anyone who relies on lidar is doomed to fail", which caused a stir in the field. Terranet followed closely, making a bold move to support Musk's view that lidar is just a dangerous shortcut for image recognition, and it will be very dangerous if the future fully automatic vehicles continue to use lidar. (picture source: terranet) the construction of voxelflow is based on the recognition that the current camera based computer vision and AI navigation system is too slow, and the frame method will be limited by the basic speed of perception. Lidar has limited resolution and slow scanning speed, so it is difficult to distinguish many objects, such as fixed lamp posts and running children. The potential problem with lidar or existing camera / computer vision technologies is that vulnerable road users cannot be detected with low latency. Voxelflow can classify dynamic moving objects with very low latency and generate 10 million 3D points per second, so as to achieve fast edge detection without motion blur. The iPhone's self timer camera produces only 33000 light points per frame. In contrast, today's standard vehicles, even those equipped with an autopilot roadmap, use cameras that are not as powerful as the phone's self timer cameras. According to statistics, 80% of crashes and 65% of near-range crashes are related to the driver's inattention within three seconds before the accident, so the performance of voxelflow is particularly important. Terranet can detect objects in milliseconds and help vehicles make correct decisions in time, thus reducing road traffic accidents. "Voxelflow can compete with lidar and will shake the field of autonomous driving and save lives," said P รค r-olof Johannesson, chief executive of terranet
