The Ensenso N series 3D cameras from IDS represent a significant leap forward in 3D image capture technology, combining impressive precision with cost-effectiveness and speed. This versatile camera family offers a powerful solution for a wide array of industrial and robotic applications, bridging the gap between high-accuracy systems and budget-conscious, high-volume projects.
Ensenso N, C, X, and XR cameras utilize the stereo vision principle, projecting high-contrast textures onto the object to be imaged. This technique, supported by a powerful projector, generates highly detailed 3D point clouds, even at considerable distances. For applications where the ultimate in accuracy isn't paramount, the Ensenso S series provides a cost-effective alternative using structured laser light, making 3D vision accessible to a broader range of projects.
The addition of an RGB sensor in the C series models adds another layer of capability. This provides 2D color information alongside the 3D data, resulting in textured 3D point clouds and exceptionally realistic 3D visualizations. This color data also opens up opportunities for downstream processing, enabling tasks such as the differentiation and sorting of colored objects.
Robustness is a key feature of the Ensenso N series. Lockable GPIO connectors for trigger and flash signals ensure compatibility with industrial environments. For demanding applications, the N3x and N4x series models are available with IP65/67 protection, safeguarding the cameras against dirt, dust, water, and cleaning agents. The N3x models utilize an aluminum housing, maximizing heat dissipation and ensuring stable light output even under extreme conditions, resulting in consistently high-quality 3D data. The robust metal construction allows for flexible and secure mounting, even accommodating short object distances.
The N4x series introduces a significant design innovation: a completely decoupled 3D stereo electronic system. This allows for a lightweight plastic composite housing, reducing manufacturing costs and weight. This lighter design makes the N4x cameras ideal for use with collaborative robotic arms, where weight limitations are critical for safety. The use of plastic also contributes to safer human-robot interaction by minimizing the risk of injury through its softer haptics and rounded edges.
Ease of use is also a priority. Ensenso N3x cameras are certified “TM Plug&Play” by Techman Robot, allowing for straightforward integration with TM robots and immediate use in 3D bin-picking applications without custom image processing development. This feature alone dramatically reduces development and integration time, saving companies valuable resources.
The Ensenso SDK simplifies setup, operation, and data processing for all Ensenso N models. This comprehensive software suite offers wizards for effortless setup and camera calibration, GPU-based image processing for faster 3D data generation, and sample programs in various programming languages. It supports multi-camera setups, creating a single 3D point cloud from multiple viewpoints, and facilitates robot hand-eye calibration. The SDK also allows integration with uEye industrial cameras for capturing additional color information or barcodes.
Finally, the Ensenso PartFinder software (requiring a separate license) allows users to locate CAD geometries within the Ensenso 3D point clouds. Leveraging depth data, surface normals, and texture information, even complex localization tasks become manageable.
In conclusion, the Ensenso N series represents a powerful and versatile solution for 3D vision applications across a multitude of sectors. Its blend of high precision, cost-effectiveness, robustness, and ease of use makes it an ideal choice for companies seeking to integrate 3D vision into their workflows, from quality assurance and factory automation to robotics and logistics.
