Heatmap

Color the image in five depth bands: blue for the nearest, then cyan, magenta, yellow, and red for the farthest. The node reads the red channel of the input as a disparity value and converts it to depth, so it is meant for the output of a depth estimation model, such as one loaded in the ONNX Image Model node. On a normal photo it colors by brightness.

Parameters

Focal Length The focal length used in the disparity-to-depth conversion.
Disparity Scale Scales the red channel before the conversion.
Depth Min and Depth Max The depth range that the five bands cover. Depths below the minimum are blue, depths above the maximum are red.
