DECEMBER 3, 2009--The 3D-Eye L smart camera system makes the third dimension accessible to the user. An evaluation processor can thread in up to 40,000 3-D profiles per second. The cabinet measures 110 x 80 x 60 mm and contains a calibrated laser triangulation sensor as well as the evaluation processor. Complete evaluation software is programmable by drag-and-drop. The system can be used for any three-dimensional inspection tasks. Results and image data can be transferred via Gigabit Ethernet, RS-232, or RS-485 interfaces.

three-dimensional vision with digital eyes
The new smart camera systems 3D-Eye L of EVT makes the third dimension accessible to the user. The cabinet measures only 110 x 80 x 60 mm and contains an already calibrated laser triangulation sensor as well as an evaluation processor. The evaluation processor can thread in up to 40000 3D-profiles per second. The complete evaluation software is contained in the system and can be programmed by drag-and-drop. All topics can be realized, from simple testing method tasks to object recognition with robots. The multiplicity of algorithms allows to solve even complex three-dimensional problems. The compact construction of the sensor and the completely integrated EyeVision software guarantee a simple three-dimensional solution. The system can be used for any three-dimensional inspection tasks.
If the evaluation of two-dimensional images do not suffice the problem can be solved in a simple way by working with the third dimension. If you want to read e.g. the font on a car wheel with a two-dimensional camera the differences of the gray scale values between the black wheel and the black font are minor. In this case a sensor permutes the difference of level between the wheel and the font in an evaluable image. Now it is already possible to realize the evaluation with the aid of the standard algorithms.
The evaluation unit and the sensor are not only integrated into the cabinet of the 3D-Eye L system they are also pre-calibrated. That means the user has the possibility to replace an existing sensor by a new one at any time without calibrating the system again. It will do to replace the old sensor by a new one and to input the testing program in the new sensor.
The field of application ranges from the RobotVision and the electronic industry to the semiconductor industry. The recognition of characters in logistic systems as well as the reading of codes do not cause a problem for the system. In this connection it does not matter whether it is a OCR, a bar code or a DMC. The EyeVision software is integrated into the sensor and has a compatible algorithm for every task.
The novelty of this system is that everything is integrated completely and therefore the three-dimensional evaluation can be programmed as simple as a normal image processing system. The pre-calibration makes sure that the user only has to look after the installation of the sensor. You can install the software with the existing monitor access that can also display results of measurement and test results. The results and the image data can be transferred via interfaces like for example Gigabyte Ethernet, RS232 or RS485. Therewith the three-dimensional sensor can be integrated into the existing business software and additionally the connection to the robot can be realized. The results of measurement can be also transferred to the business software of SAP and ORACLE via optional software interfaces. Consequently the test results are available in the company anywhere and at any time.
