Morphos - Development of a measuring system for verifying existing models from combustion engine industry
(details) |
An apparatus for generating high resolution digital images using a translationally moved CCD-line-camera was realized. With it, objects which have been given a special texture can be imaged comfortably. By tilting the camera and the different perspectives that result from this, it is possible to perform a 3D reconstruction of surface points. The measured object can be turned automatically in the scanning space, which makes it possible to get views from all sides. This requires an exact registration of the individual views in relation to each other. A surface description which clearly reproduces the object is derived from the 3D point cloud that results from the recorded views just mentioned. The accuracy reached is 0.1 mm for the RMS-error in space and 0.1( for the determination of the object rotation. The scanning volume is 500(150(150 mm3. This results in a relative accuracy of 1:5000. Clearly, the requirement of 1:1000 has been reached. The complete reconstruction of a complex object such as e.g. a water cooling jacket with a length of 500 mm takes about one week, where one day of user interaction is required for making the recordings and about one hour is needed for the preparation of the reconstructed point data for the surface reconstruction. What remained unsolved in this project is the problem of generating a fully closed surface for very complex objects without a significant amount of user interaction. In this area there is room for further development.

Flexible Assembling Unit for Industrial Applications
(details) |
The series production of parts with a small to medium number of units requires a fast and inexpensive adaption to new parts. A pure hardware solution, as it is common for example in the motor industry, is contrary to the above requirement. The goal of this project is to develop a vision driven, flexible and automatic assembling unit. In order to solve this demanding task, the separation into three, from the viewpoint of vision almost independent steps is proposed. The first step is to isolate one part from the pile. This task is generally referred as binpicking. Where the task of step one was to detect one plane among many parts of one class the task now is to determine the exact position of one known part (step 2). And the third step is the surveillance of the assembling itself. |
