Architecture for contextual memories in map representation for 3D reconstruction and navigation

A method for contextual memory mapping, comprising:

• receiving a data set of physical world sensor readings of a physical area;
• generating voxel data from the data set, wherein the voxel data includes voxel coordinates of the physical area and an indication of physical world occupancy in the physical area for each voxel coordinate;
• selecting a block of addresses in the memory to store the voxel data;
• generating a hash map to map voxel coordinates to memory locations in the block of addresses based on proximity of the voxel coordinates in the physical area, wherein selection of the memory locations of the voxel coordinates maintains the proximity of the voxel coordinates, the block of addresses represented by a plurality of bits, the plurality of bits separated into blocks of bits, a number of bits dependent on dimensionality of the voxel coordinates, a number of blocks of bits dependent on a maximum level of discretization of voxels within the physical area, each block of bits representing a directional vector that is independent from directional vectors of other blocks and has a vector length that is different than vector lengths of the other blocks;
• and
• storing the voxel data at memory addresses within the block of addresses in the memory based on mappings of the hash map.

At least one non-transitory computer readable medium including instructions for contextual memory mapping that when executed by at least one processor, cause the at least one processor to:

• receive a data set of physical world sensor readings of a physical area;
• generate voxel data from the data set, wherein the voxel data includes voxel coordinates of the physical area and an indication of physical world occupancy in the physical area for each voxel coordinate;
• select a block of addresses in the memory to store the voxel data;
• generate a hash map to map voxel coordinates to memory locations in the block of addresses based on proximity of the voxel coordinates in the physical area, wherein selection of the memory locations of the voxel coordinates maintains the proximity of the voxel coordinates, the block of addresses represented by a plurality of bits, the plurality of bits separated into blocks of bits, a number of bits dependent on dimensionality of the voxel coordinates, a number of blocks of bits dependent on a maximum level of discretization of voxels within the physical area, each block of bits representing a directional vector that is independent from directional vectors of other blocks and has a vector length that is different than vector lengths of the other blocks;
• and
• store the voxel data at memory addresses within the block of addresses in the memory based on mappings of the hash map.
