Abstract: 3D space modeling is crucial for AR/VR applications and navigation services in indoor environments. However, the conventional approaches require specialized devices, such as cameras, depth sensors combined with structured-light/laser pointers, 3D laser scanners, and so on. The requirements of specialized devices are potential barriers to the popularization of 3D space modeling. This paper proposes a brand new "DIY" 3D space modeling system, called "AirPlanes". AirPlanes utilizes VSLAM technology, which has become available for mobile OS'es and generates planes in a 3D space model without the need for any proprietary sensors. The system uses a smartphone and a laser pointer and takes a laser-based active-sensing approach to plane-model generation integrated with VSLAM. The device is a “do-it-yourself” one combining a smartphone and off-the-shelf laser pointer. It estimates the projected laser dot's world coordinates by triangulation in real time. Through integration with VSLAM-based self-positioning, it makes 3D plane modeling possible, even for flat and monotone walls that current feature-point-based VSLAM recognition technology cannot measure.
