3D Laser Scanning
3D laser scanning accomplishes high-quality three-dimensional measurement of complex objects, generating both incredibly accurate geometric models and stunning photorealistic texture in less time than traditional recordation. For straightforward object recordation, metric analysis, reverse engineering and rapid prototyping, 3D laser scanning offers great flexibility and accuracy on a moderate budget. Objects from the size of a coin to full-sized vehicles can be quickly and accurately measured with sub-millimeter accuracy. Models created through 3D laser scanning can be imported into other mainstream 3D modeling, CAD/CAM, and engineering software applications for analysis, viewing, and manufacture.
A 3D laser scanner measures objects by emitting a laser line, which sweeps across the field of view. A digital video camera records the laser line, calculating the size and shape of objects within the field of view by analyzing the “bends” in the line as it sweeps non-flat surfaces. The measurement data is recorded to a CCD, and a color image of the scene is attached. By moving the object, or the scanner, multiple measurements are collected, which are then aligned and merged to create a solid model of the entire object.
