The patient joined the session outside near Science Park in Amsterdam, was captured with a Samsung S20 Ultra 5G smartphone, and streamed over the standard 5G network of KPN in real-time.<\/span><\/p>\n\n\n\n<p>The capture application on the phone uses the depth and color cameras to capture depth and color frames. After applying some alignment transformations, a point cloud is computed using the information on both frames. For the demo, we used a depth resolution of 240&times;180 pixels which turned into an average of 20.000 points per frame. The streaming was performed at 20fps, which turns into a 51.2 Mbits\/second stream, too big for streaming over a 4G network (typical uploading velocity around 25Mbits\/s), but enough for a 5G network (even at 700MHz).<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Depth resolution: 240&times;180<\/li><li>Max points: 20000<\/li><li>Bytes\/point: 16<\/li><li>Bytes header: 24<\/li><li>Bytes body: 320000<\/li><li>Total bytes\/frame: 320024<\/li><li>FPS: 20<\/li><li>Mbytes\/s: 6,40<\/li><li>Mbits\/s : 51,20<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-gallery columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"573\" src=\"https:\/\/blog.laval-virtual.com\/wp-content\/uploads\/2021\/01\/vrtogether-vrdays-europe-2020-volumetric-video-conference-5g-capture-mobile-1.jpg\" alt=\"\" data-id=\"11744\" data-link=\"https:\/\/blog.laval-virtual.com\/?attachment_id=11744\" class=\"wp-image-11745\"\/><figcaption>Capturing point clouds from a mobile phone<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"712\" height=\"396\" src=\"https:\/\/blog.laval-virtual.com\/wp-content\/uploads\/2021\/01\/vrtogether-vrdays-europe-2020-volumetric-video-conference-5g-network-amsterdam-1.jpg\" alt=\"\" data-id=\"11746\" data-link=\"https:\/\/blog.laval-virtual.com\/?attachment_id=11746\" class=\"wp-image-11747\"\/><figcaption>Caracteristics of the 5G Network around Amsterdam&rsquo;s park<\/figcaption><\/figure><\/li><\/ul>\n\n\n\n<p>The&nbsp;<a rel=\"noopener noreferrer\" href=\"https:\/\/vrtogether.eu\/project-outcomes\/project-results\/\" target=\"_blank\">VRTogether platform<\/a>&nbsp;was used for orchestrating the experience.
