Ensenso™ 3D Camera
IDS Ensenso™ 3D Camera Simplifies Bin Picking with Reduced Cost and Labor Time
Ideal 3D Solution for OEMs and Vision System Integrators
WOBURN, MA -- The Ensenso™ stereo 3D camera from IDS is an industrial solution for robot vision, achieving high precision in the most complex vision tasks, including the challenging bin picking of parts and on-the-fly volume measurements. Unlike other 3D cameras on the market, the Ensenso is easy to integrate, eliminates the need for complicated setups, and breaks new ground in terms of speed.
Currently available with a standard USB connection, the Ensenso will soon be offered with a GigE PoE connection to broaden its versatile design.
The Ensenso is the first 3D camera to integrate not only two global shutter CMOS sensors in a very compact housing, but also an infrared pattern projector. This feature projects a random pattern of dots onto the object to be captured, allowing structures that are not visible or only faintly visible on the surface to be enhanced or highlighted. The object is then captured by the two image sensors in accordance with the stereo vision principle. Once captured, 3D coordinates are calculated for each and every pixel using geometric relations.
"The Ensenso's stereo vision engineering means that, even if parts with a relatively monotone surface are placed in the bin, a virtually seamless and detailed 3D image of the entire surface can be generated without additional technical effort," explained Daniel Seiler, Chief Operating Officer, IDS Imaging Development Systems Inc. "All of this happens in just a few milliseconds. As a result, the robot vision applications can 'cover all bases' in terms of requirements for short cycle times, availability and cost efficiency."
The Ensenso is designed for working distances of 130 mm to 2,000 mm and for variable picture fields. Its available focal lengths of 3.6 to 16 mm can cover a wide range of distances and sizes. Even with its two sensors and integrated projector, the camera measures just 150 x 45 x 45 mm.
OEMs and system integrators will find the Ensenso is ready for immediate use and delivers 3D data out of the box, so it can be installed straight away. All that remains is for the robots to be calibrated for working with the camera, a simple step done using a calibration plate mounted on the robot arm. Included software uses this plate to calculate the mounting position of the camera, and the 3D data is immediately represented in the robot's coordination system. The 3D point clouds can be analyzed by all standard machine vision programs, including HALCON. The HALCON interface is included in the Ensenso's comprehensive software package, alongside an API for C, C++ and C#.
