Paper Abstract

We present a technique for measuring the area of mesa shaped features of constant height and irregular outline starting from a pair of stereo images captured above the feature. Our method is based on correlating the sign images of the Laplacian of Gaussian convolution of the two grey-level images'. We generalise this method to measure the volume of an irregularly shaped pile of material, such as a blob of sol-der paste which has been applied to a circuit board in preparation for reflow soldering.
