The Heatmap Widget overlays a video snapshot with a visual representation of the cumulative value of a selected attribute across the monitored scene. This visualization helps to quickly identify traffic patterns, congestion areas, and hotspots.
Available Attributes
The Heatmap Widget allows you to select from the following attributes:
Occupancy map, showing how much time objects spend at each pixel position.
Acceleration map, displaying the intensity of acceleration per pixel.
Speed map, highlighting how high the speed of traffic objects was on each pixel.
Gridmap Subtype
The Gridmap subtype groups individual pixels into larger square tiles of configurable size. Each square can display calculated values directly inside the grid cells, such as minimum, maximum, average, or median values, offering an aggregated view of the data across the scene.
