This brings a new challenge of how to monitor and enforce social distancing when everyone is back on the roads.</div><div><br></div><div>CCTVs would be crucial in monitoring and enforcing social distancing in public places and in workplaces; The manual overhead in doing it is very high, fortunately if there's one thing which AI has proven itself as more capable than human beings it's computer vision.</div><div><br></div><div>But, since average CCTVs don't have depth perception, have different views and people are not in the same plane of axis; judging the distance between two people from video footage is a hard problem. Fortunately, Andrew Ng's company has released a tool to do just this and has released how the procedure works - <a href="https://landing.ai/landing-ai-creates-an-ai-tool-to-help-customers-monitor-social-distancing-in-the-workplace/">https://landing.ai/landing-ai-creates-an-ai-tool-to-help-customers-monitor-social-distancing-in-the-workplace/</a>.</div><div><br></div><div>It solves the problem of calculating distance by using homography to get top-down view of the image from video, using a manual calibration tool. Unfortunately, none of this has been open-sourced as of writing and hence a need gap for this to be released as an open-source tool for any govt. or workplace to make use of.</div><div><br></div><div>Such a tool can also be used on open CCTV feeds from Shodan, Insecam to analyse social distancing in countries around the world.</div> 1 points posted by Abishek Muthian /problems/111-automatic-monitoring-of-social-distance-via-cctv-artificialintelligence-socialdistancing 111 Fri, 17 Apr 2020 16:52:00 +0000
