Abstract

Presented are deep learning-based systems and methods for fusing sensor data, such as camera images, motion sensors (GPS/IMU), and a 3D semantic map to achieve robustness, real-time performance, and accuracy of camera localization and scene parsing useful for applications such as robotic navigation and augment reality. In embodiments, a unified framework accomplishes this by jointly using camera poses and scene semantics in training and testing. To evaluate the presented methods and systems, embodiments use a novel dataset that is created from real scenes and comprises dense 3D semantically labeled point clouds, ground truth camera poses obtained from high-accuracy motion sensors, and pixel-level semantic labels of video camera images. As demonstrated by experimental results, the presented systems and methods are mutually beneficial for both camera poses and scene semantics.
