PPT-VELO Motion Mechanics & Motion PLC

Motion review 16 November 2010 Frans Mul Martin Doets Marco Kraan Piet de Groen Fred Schimmel Eddy Jans MvB Outline Introduction Motion mechanics Overview of PLC and hardware. What affects the induced image motion?. Camera motion. Object motion. Scene structure. Example Flow Fields. This lesson – estimation of general flow-fields. Next lesson – constrained by global parametric transformations. Dr. Mohammad Kilani. Class 5. CAMS. Introduction to Cams. Cam-follower systems are frequently used in many kinds of machines. Common examples of cam follower systems are the automobile engine valves, which are opened by cams. . Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Conceptual Model. – a set of concepts that describe a subject and allow reasoning about it. Mathematical Model. – a conceptual model expressed in symbols and equations. Data Model. – a conceptual model expressed in a data structure (e.g. ascii files, Excel tables, …..). Given a set of corresponding points in two or more images, compute the camera parameters and the 3D point coordinates. Camera 1. Camera 2. Camera 3. R. 1. ,t. 1. R. 2. ,t. 2. R. 3. ,t. 3. ?. ?. ?. Slide credit: Noah . Examples:. Pendulum.. Oscillating spring (either horizontal or vertical) without friction.. Point on a wheel when viewed from above in plane of wheel.. Physics Classroom has a good lesson on simple harmonic motion under Waves, vibrations.. Nature of science: . Observations: The ideas of motion are fundamental to many areas of physics, providing a link to the consideration of forces and their implication. The kinematic equations for uniform acceleration were developed through careful observations of the natural world.. – a set of concepts that describe a subject and allow reasoning about it. Mathematical Model. – a conceptual model expressed in symbols and equations. Data Model. – a conceptual model expressed in a data structure (e.g. ascii files, Excel tables, …..). behaviour. of the universe, from the very smallest scales of sub-atomic particles to the very largest in cosmology. It applies these laws to the solution of practical problems and to the development of new technologies. . . Motion. Speed & Velocity. Acceleration. Newton’s First Law. Newton’s First Law of Motion. An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force.. . Annual Motion. DIURNAL MOTION. Daily East / West motion of the sky. Due to the Earth’s rotation (15°/hour). [360°/24 hours = 15°/hour]. [1° in 4 minutes]. Stars fall into two groups. Circumpolar - never rise or set. Recording Secretary, IEEE 802 LMSC. jdambrosia@ieee.org. . Purpose of this document. The purpose of a motion template is to improve the quality of the work of the EC . Used properly, these motion templates should result in the reduction of motions that are incomplete or ambiguous and the reduction of gratuitous variation . the . process of moving . or . changing . places . or position. Anything you do while moving is motion.. Fact: Speed is a major type of Motion. Determining motion. In order to determine motion you must know direction and speed. Describing motion is occasionally difficult to do with words. Graphs can help simplify this description greatly. Position = Distance from a starting point. Velocity = rate of change in position. Acceleration = rate of change in velocity.
