Abstract
Techniques are described for modifying a factor associated with an invalid point cloud registration (e.g., alignment) between two data sets, to improve a map generation process. A computing system receives sensor data from a vehicle traversing an environment. The computing system aligns discrete data sets, such as to generate a representation of the environment based on the discrete data sets. In some examples, the computing system can apply an optimization algorithm to the alignments, to optimize the representation of the environment. The computing system identifies an invalid (non-ideal) alignment between two data sets and modifies a factor associated with the invalid alignment, introducing a repulsive force. The computing system performs an optimization with the modified factor, which causes a location associated with at least one of the two data sets to be different from a previously measured location. The computing system generates a map based on the optimization.
