Nitere
Estimate real-world luminance from still images and video frames. Calibrate your camera, draw a region of interest around any shape, and read luminance values for accident reconstruction, visibility analysis, and lighting assessment.
Why Nitere
- Capture on the move Estimate luminance from video frames recorded while driving through a scene, with no roadside stops or lane closures.
- Your camera, your workflow Calibrate the camera setup you already use instead of hauling dedicated luminance-camera hardware into the field.
- Any shape, any size Measure non-uniform objects by drawing the region you care about, rather than collecting spot-meter readings point by point.
How it works
Build a dataset
Load your calibration images, draw regions of interest, and record reference luminances.
Fit a model
Fit a linear or exponential calibration model from the dataset you captured.
Estimate luminance
Apply the model to new images and read predicted luminance for each region.
Visibility level
Compute Adrian visibility levels for targets against a background in the scene.
