Three-dimensional reconstruction using geometry models for interior space monitoring systems and applications

Abstract

In various examples, geometry model-based three-dimensional reconstruction for interior space monitoring systems and applications are provided. An interior geometry model may be used to reconstruct a 3D geometry of an interior by selecting distinct regions of interest corresponding to interior surface regions. A point cloud representation of one or more selected regions may be generated using the vehicle interior geometry and a set of commonly oriented 3D bounding shapes (e.g., bounding boxes generated with respect to a shared coordinate system) may be generated to bound the selected interior surfaces. Bounded point cloud samples may be projected onto a surface using a surface fitting algorithm to estimate a best non-circumscribed polygon region model, which provides a geometric framework for reconstructing a 3D geometry that may be used to obtain direct measurements of 3D relationships between the selected regions of interest and OMS sensors.
