Paper Abstract:	This paper proposes new development framework based on OpenVSLAM for web-based VR tours using 360VR videos. Although the authors have already proposed the development framework for web-based VR tours as navigation contents of 360VR videos and as walkthrough contents of 360VR images, it is not easy to prepare 360VR images because the authors took over 300 360VR images at different locations for the walkthrough contents of 360VR images introduced in this paper. Therefore, in this paper, the authors propose new development framework for web-based VR tours as both navigation contents and walkthrough contents from 360VR videos. For walkthrough contents of 360VR images, 360VR videos of navigation contents can be used instead of 360VR images because required 360VR images can be extracted from 360VR videos of the same scene. In this case, only 360VR videos of a portable 360VR camera like Insta360 ONE X2 are enough. The development framework for navigation VR tours of 360VR videos need their moving path information and for walkthrough VR tours of 360VR images need their location information. The authors have created them manually so far. For generating them automatically, the authors decided to employ OpenVSLAM. This paper shows evaluation results how accurate moving paths and location information can be generated by OpenVSLAM.
