    7) Publication of the week - Pseudo-LiDAR from Visual Depth Estimation:Bridging the Gap in 3D Object Detection for Autonomous Driving (2019).
    arXiv
    INFO: We found the above paper cited in several articles ([1], [2]) that surfaced after Elon Musk made a statement about LiDARs being a fool’s errand during Tesla autonomy days earlier this week. We’ve decided to see ourselves what the paper says and if stereo cameras will beat LiDARs any time soon. The paper has been written by Cornell University Researchers. In the paper they propose an alternative method for representation of 3D information obtained from stereo cameras so that it resembles LiDAR data (pseudo-LiDAR) and therefore LiDAR based object detection algorithms can be applied to it. The experiment setup is based on the KITTI benchmark and there are two algorithms that Researchers evaluate: F-POINTNET-v1 and AVOD-FPN. Looking at the results table the chosen approach is a significant improvement over other camera based methods however at high Intersection over Union there is still a high gap between stereo based method described and Lidar + monocular camera based method. In case of Bird Eye View representation with AVOD algorithms and the IoU of 0.7 the researchers obtained a result of 74.9 (89.4 for LiDAR + mono camera) in Easy category and 49.0 (79.3 for LiDAR + mono camera) in Hard category.
