Reverse Engineering Using Optical 3D Sensors
نویسندگان
چکیده
Optical 3D sensors are used as tools for reverse engineering: First the shape of an object is digitized by acquisition of multiple range images from different view points. Then the range images are registered and the data is turned into a CAD description, e.g. tensor product surfaces, by surface modeling software. For many applications however it is sufficient to generate a polyhedral surface. We present a nearly automatic procedure covering the complete task of data acquisition, calibration, surface registration and surface reconstruction using a mesh of triangles. A couple of measurements, such as teeth, works of art and cutting tools are shown.

Intelligent Laser Scanning of 3D Surfaces Using Optical Camera Data
aBstract In CAD/CAM, reverse engineering involves obtaining a CAD model from an object that already exists. An exact replica can then be produced, or modifications can be made before manufacture. Single-perspective triangulation sensors provide an inexpensive method for data acquisition. However, such sensors are subject to localised distortions caused by secondary reflections or occlusion of t...
متن کاملImplementation of 3D Optical Scanning Technology for Automotive Applications
Reverse engineering (RE) is a powerful tool for generating a CAD model from the 3D scan data of a physical part that lacks documentation or has changed from the original CAD design of the part. The process of digitizing a part and creating a CAD model from 3D scan data is less time consuming and provides greater accuracy than manually measuring the part and designing the part from scratch in CA...

In addition to CAD techniques currently used to produce a 3D model of an artifact for subsequent prototyping, 3D acquisition by means of optical digitizers is dramatically growing as a powerful companion of rapid prototyping, for the creation of prototypes from existing objects such as maquettes, sculptures and body parts. The availability of a large amount of 3D acquisition systems on the mark...
متن کاملWeight Measurements by Using Simple Optical-Fiber Sensors (RESEARCH NOTE)
The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...
