Scanning / Laser 3D
ERGOTECH uses a Cyberware 3030RGB laser scanner mounted on a PS rotating platform for the capturing of three-dimensional form data of objects. During digitizing of an object, a safe, low-intensity (grade 1) laser is projected onto the object to create a highlighted profile. A high-quality video sensor captures this profile from two viewpoints. The system digitizes hundreds of these profiles in a few seconds to capture a three-dimensional (3D) replica of the object in space. Simultaneously, a second video sensor captures colour information of the object. The addition of colour information to 3D digitizing provides nearly all the information a graphics application requires to fully describe an object. In addition to enhancing realism in graphic models, colour denotes boundaries that are not obvious from shape alone. The digitized and colour data are transferred to a graphics workstation for immediate viewing and modification. An object (of a maximum size of W 300 mm x H 300 mm) can be digitized and displayed on the graphics workstation in less than half a minute. Digitized objects will have a spacial resolution of between 0,1 mm and 2 mm depending on object size, and can be exported in 3D studio, ASCII, dxf, iges (106, 124, 128), inventor, obj, ply, scr, stl and vrml file formats to be imported directly into a number of CAD or computer animation packages.

3D Anthropometry

Traditional anthropometry (measurement of the human body dimensions) uses physical measurement of the human body with use of typical anthropometric “tools” such as tape measures and anthropometers. With advances in technology, the development of 3D imaging equipment such as laser scanners opened the doors to advanced, three-dimensional anthropometry. ERGOTECH currently uses the Cyberware 3D laser scanner for data acquisition and research on 3D head anthropometry. This research has extended to the development of head models representative of the South African population as well as evaluation and development of headgear such as protective facemasks. Further current research involves advanced 3D anthropometric research and evaluation of cranio-facial equipment such as a variety of helmets and research on interface problems with cranio-facial equipment.

Reverse Engineering

ERGOTECH provides a solution to your reverse engineering needs. With the use of our 3D laser scanner, an exact replica of any object is obtained in electronic format within seconds. Using laser scanning as a means of obtaining a digitized replica of an object is advantageous especially where physical contact with the object is not preferable and where measurement time must be kept as short as possible. Once the object is in digitized format, it can be imported into free form engineering CAD packages to be manufactured using processes such as CNC machining, stereollthography or fused deposition manufacture. Modifications such as scaling, deformations, or negatives can also be made using the scanned object on the CAD work environment before manufacturing.
