Multi-Resolution Voxel Alignment for Faster Vehicle Mapping

The patent segments the alignment process by resolution levels, dividing the multi-resolution voxel space alignment into multiple stages. Each stage processes a specific resolution level, allowing the system to handle coarse resolutions first for rapid initial alignment, then progressively refine with finer resolutions. This segmentation enables parallel processing of different resolution layers and reduces the computational burden on any single resolution level, thereby decreasing overall processing time while maintaining alignment accuracy.

The patent applies preliminary action by performing alignment operations on coarser resolution levels before processing finer resolutions. The coarse-resolution alignment establishes an initial transformation that serves as a foundation for subsequent fine-resolution alignment. This preliminary coarse alignment reduces the search space and computational complexity for finer resolutions, enabling the system to achieve accurate alignment more efficiently by avoiding direct processing of all fine details from the outset.

The patent segments the computational workload by organizing voxel processing into resolution-based groups that can be handled independently. Each resolution level is processed as a separate computational task, allowing for optimized resource allocation. The system can allocate computational resources dynamically across different resolution levels, processing coarse resolutions with fewer resources and reserving higher computational power for fine-resolution details only when needed, thus reducing overall computational resource consumption.

The patent performs preliminary coarse-resolution alignment to establish an initial transformation framework before engaging computationally intensive fine-resolution processing. This preliminary action reduces the complexity of subsequent computations by providing a pre-established reference frame, thereby minimizing the computational resources required for achieving final alignment accuracy. The coarse alignment serves as a computational shortcut that avoids exhaustive processing of all fine details.
