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.Type: GrantFiled: February 9, 2018Date of Patent: June 8, 2021Assignees: Baidu USA LLC, Baidu.com Times Technology (Beijing) Co., Ltd.Inventors: Peng Wang, Ruigang Yang, Binbin Cao, Wei Xu
