Purpose

This sample program demonstrates how to:

• Apply photometric stereo to several images to retrieve their albedo, gradients, curvatures or height map.

Code highlights

Use the recommended images:

• Calibration: the 4 calibration_* files.

• Sample: either the 4 object2_* or the 4 shoe_* files.

1. Calibrate the imager from images of a sphere and retrieve a score.

   calibrationScore_ = photometricStereoImager_.CalibrateFromSphere(rois);
   

2. Compute the intermediary photometric stereo results from the images of the object.

   photometricStereoImager_.Compute(rois);
   

3. Compute the mean curvatures and retrieve them in an EImageBW8 with high contrast.

   meanCurvHighContrast_ = photometricStereoImager_.ComputeMeanCurvatures(EPhotometricStereoContrast.HighContrast));
