Sample Computer Vision Questions Block World Models Suppose you asked are to build a computer vision demonstration system for a children's museum. The idea is to have a "playroom" with a variety of building blocks and have a computer controlled robot arm pick up the blocks and build things for the children. Your job is to make one or more cameras mounted on the wall to obtain a geometric model of the blocks which will be used as input data by the robot control system. • Describe how you would "set up" the cameras and the playroom to make the job of obtaining geometric models as simple as possible. Explain what your objectives are and how your choices simplify the problem. • Describe how you would process the input image to detect the visible edges of the block faces. Explain your edge detection algorithm in detail. What are some of the factors which will influence the accuracy of this algorithm? Smoothing
