We present a method to evaluate the shape of 3D micro products from several images. The data acquisition system consists of a digital microscope, and a computer controlled turntable. We employ a so called Shape-From-Silhouette (SFS) method which constructs a voxel-based 3D model from silhouette images. The obtained voxel model is further carved by the space carving technique. As a final step, we employ marching cubes technique to convert the voxel model to triangular meshes. The reconstructed models of complex objects show the effectiveness of our inexpensive data acquisition system.
