Fun with Seoul CCTV Live


Using live traffic cctv data of city Seoul, I tried to project 'Time' to the '3-demensional cubic space'.
Real-time CCTV video from all over Seoul provided by the Seoul Metropolitan Police Agency is analyzed through the background detection of OpenCV.js to extract moving objects.

In the 3-demensional space implemented by THREE.js, an axis orthogonal to a live streaming video is set as 'Time', and extracted images are constantly translated in the opposite direction of the axis to visualize the 'Time' information from the past to the present of the moving object and fuse 'Time' with '3D Space'.
