Description of data collection: | The intensity values of the time-of-flight camera are calibrated to Lambertian targets with well-defined reflectance values at 10%, 50% and 95% [1]. From the calibration process, a relation between intensity and reflectance of the Lambertian target is derived. Of the 300 frames taken by the time-of-flight camera with a resolution of 352×287 pixels, only the last 101 frames are considered. A line of 41 pixels perpendicular to the tilting angle of the image center at pixel row 145 of each of the frames, summing up to a total of 4141 datapoints is considered for evaluation. An outlier detection function of MATLAB with the Grubbs’ test method removes outlier datapoints. The average intensity is then used to calculate the reflectance value in the dataset. |
