Spatial construction using guided surface detection
Described herein are a system and methods for efficiently using depth and image information for a space to generate a 3D representation of that space. In some embodiments, an indication of one or more points is received with respect to image information, which is then mapped to corresponding points within depth information. A boundary may then be calculated to be associated with each of the points based on the depth information at, and surrounding, each point. Each of the boundaries are extended outward until junctions are identified as bounding the boundaries in a direction. The system may determine whether the process is complete or not based on whether any of the calculated boundaries are currently unlimited in extent in any direction. Once the system determines that each of the boundaries is limited in extent, a 3D representation of the space may be generated based on the identified junctions and/or boundaries.
1. A method of generating a three-dimensional (3D) representation of a space comprising:
receiving an indication of a number of points, each of the points corresponding to a location upon a surface of a structural feature within the space;
determining, for each of the number of points, a number of corresponding boundaries that match the surface of the corresponding structural feature for at least some amount of area;
identifying, from the determined number of corresponding boundaries, multiple pairs of intersecting boundaries;
generating a set of junctions, wherein each junction is generated as an intersection of a pair of intersecting boundaries of the multiple pairs of intersecting boundaries; and
after determining that each of the number of corresponding boundaries are completely limited in extent by junctions within the set of junctions, generating the 3D representation of the space using the set of junctions.
