ENT 3634 Machine Vision Systems Core Course Lecture

ENT 363/4 Machine Vision Systems (Core Course) Lecture 2 Introduction to Machine Vision From wikipedia: Machine vision (MV) is the technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance in industry. “The scope of MV is broad”. 1 of Mechatronic Engineering School Ai.

WHY? Interest in image processing stems from two principle application areas: Ø improvement / enhancement of pictorial information for human interpretation do you have example in mind? Ø Processing of image data for storage, transmission, and representation for autonomous machine perception. which is why we learn this course! 2 School of Mechatronic Engineering Ai.

Some Definition § Images are two-dimensional projections of the three-dimensional world § Vision is the most Complex of human senses, about a fourth of the brain’s volume is devoted to it. § Image Processing images to give new images § Computer Vision Deals with what the images mean – aims to interpret images § Machine Vision Apply vision and image processing § Vision System A Vision System recovers useful information about a scene from its two dimensional projections 3 School of Mechatronic Engineering Ai.

Components of Machine Vision Systems Image acquisition • Describe images, objects and physical world – dedicated camera and frame grabber are used. • Mathematical models of image and objects and knowledge representation. • Image sampling, quantization Image processing • Improves image for human and computer consumption, highlight / extract relevant feature • Remove noises, deblurred etc • Color Conversion • Segmentation and representations • Extract features such a edge, regions, surfaces etc. • Measurement Analysis - measure features on the object Classification • Determine which is what in an image • Locate objects in the image, classify them and build 3 D models. • Input signal for the next actions. 4 School of Mechatronic Engineering Ai.
