While Lidar scanning, photogrammetry and rotating camera systems can lead to produce spherical images, compact dual-fisheye cameras are accurate enough for many uses, such as virtual tour, and easy to use by a non-expert. Classical methods require the images to be placed manually on a blueprint of the environment.\n%But the classical software consider placing a few images manually on the blueprint of the environment. \nThen, the user navigation in the virtual monument is limited to generated transitions between a few locations. \n\nInstead of a few pictures, this paper considers a spherical video recorded while walking within a monument and illustrates how to explore spatial dimensions of the environment where the video was taken, beyond the time scroll-bar. To this end, spherical visual Simultaneous Localization And Mapping (SLAM) and the alignment of the resulting map to an architectural blueprint are combined to create a spatio-temporal virtual tour from a video. \n<\/ul>\n<h3>Demonstration<\/h3>\n<ul>\nThe concept is demonstrated on the al-Qarawiyyin Mosque in Fez, Morocco, with access to the virtual tour interface at this <a href=\"https:\/\/home.mis.u-picardie.fr\/~mouaddib\/al-Qarawiyyin\/\">link<\/a>.\n<\/div>\n\n\n\n<h3><\/h3>\n","protected":false},"excerpt":{"rendered":"<p>Abstract Spherical images are particularly adapted to develop virtual tours of heritage monuments.
