Efficient and Scalable Object Localization in 3D on Mobile Device

Abstract

<p>Two-Dimensional (2D) object detection has been an intensely discussed and researched field of computer vision. With numerous advancements made in the field over the years, we still need to identify a robust approach to efficiently conduct classification and localization of objects in our environment by just using our mobile devices. Moreover, 2D object detection limits the overall understanding of the detected object and does not provide any additional information in terms of its size and position in the real world. This work proposes an object localization solution in Three-Dimension (3D) for mobile devices using a novel approach. The proposed method works by combining a 2D object detection Convolutional Neural Network (CNN) model with Augmented Reality (AR) technologies to recognize objects in the environment and determine their real-world coordinates. We leverage the in-built Simultaneous Localization and Mapping (SLAM) capability of Google’s ARCore to detect planes and know the camera information for generating cuboid proposals fromanobject’s2Dboundingbox. Theproposedmethodisfastandefficientforidentifyingeveryday objects in real-world space and, unlike mobile offloading techniques, the method is well designed to work with limited resources of a mobile device.</p> <p><br></p>
