“Light Detection and Ranging” or LIDAR is a method of measuring distance with pulsed laser light. The pulsing laser is aimed at an object or surface and the reflected light is measured with a sensor. A model is rendered by calculating the distance the light has traveled. It is commonly used for surveying to make high resolution maps.
Motion Capture is used to record the movement of people or objects. Capturing the visual appearance of an object is not as important as capturing its movement through space. Motion capture is used in a wide range of fields including the military, entertainment and health industries, and in robotics.
Photogrammetry is used to generate measurements from photographs. This technique can generate maps, drawings, or 3D models. The two main types of photogrammetry are Aerial Photogrammetry (a view from the sky) and Terrestrial Photogrammetry (a view from the ground). A series of images are cross referenced to calculate changes in surface and form.
Profile scanners (or laser scanners), are used to detect, measure, and analyze the profiles on an object’s surface.
Structured-Light scanning starts with the projecting a light patterns on to an object. The pattern deforms as it meets surfaces, and the deformations provide a means of measuring depth and surface information.
3D Body Scanning techniques can capture the human form as a point-cloud to reveal exact proportional and ergonomic measurements. Technologies include but are not limited to structured-light scanning, 3D depth sensing, and stereoscopic vision.
This project would not have been possible without the help and support of the Teaching Learning Enhancement Fund Grant program. SALA offers its sincere thanks and gratitude to the TLEF program, its organizers, and the students of UBC who fund the program. Thank you for your support in our project.
