Video motion analytics - creating heatmaps to visualize infrastructure usage and visitor frequency

Connected cameras in city environments track critical data points, such as visitor frequency and infrastructure usage. Networked cama streams can provide valuable sources for video data analytics, complementing the digital twin of a city environment with an enhanced real-time view of the onsite situation.

This demo is a quick test exploring the capabilities of augmenting the camera stream using Unity VideoPlayer. The VideoPlayer renders the video frames into a texture used by a simple detection method to generate a heatmap indicating moving object frequency. The detection is based on contrast change in the histogram between frames. Areas with more motion are colored as a heatmap on top of video frames using the Motion Heatmap Analyzer Tool from Unity AssetStore.

The ideal infrastructure would pass the video frames to a neural network and augment the results in the camera view to create meaningful visualizations of generated data insights and raise alerts on non-compliant situations.
