MACHINE LEARNING-BASED SYSTEM AND METHOD FOR GENERATING SEMANTIC MAPS FOR OFFROAD AUTONOMY MACHINES
A mapping system for an autonomous mobile robot includes a 3D convolutional encoder network that generates 3D feature maps from 3D point cloud data. The network sequentially compresses the feature dimension of the 3D input data to reduce the computational complexity and enable feature extraction to be performed in substantially real-time. Skip connections connect the outputs of the encoder layers of the convolutional encoder network to counterpart decoder layers of a 2D convolutional decoder network. An attention-based 3D to 2D projection layer receives the 3D feature maps generated by the encoder layers via the skip connections and projects the 3D feature maps onto 2D BEV feature maps which are provided to the counterpart decoder layers as input. The projection layer automatically estimates ground level of 3D feature maps and filters out overhanging objects that are irrelevant to ground-level navigation.
