3D vision allows the perception and understanding of the three-dimensional structure of objects. More traditional imaging systems capture images in two dimensions, which provide information about the appearance of objects but this can lack the depth information. 3D vision systems can capture this, along with the visual appearance, allowing for a more comprehensive understanding of the scene.

3D vision uses techniques such as stereo vision, structured light, time-of-flight (ToF), and laser triangulation to generate 3D images. It is used in a variety of applications, including robotics, quality control, autonomous navigation, augmented reality, virtual reality, and medical imaging, among others.

In terms of the components required, cameras are the main devices used to capture images or depth information, while light sources are used in techniques such as structured light and laser scanning, to project patterns onto the scene. These include LEDs, lasers, and other sources, depending on the specific application.

Image processing algorithms are used to capture images or depth data to extract 3D information, and depth sensors are designed to capture depth information without relying on stereo vision or structured light. Then there is the software, which is used for controlling hardware components, implementing image processing algorithms, and visualising or analysing the resulting 3D data.

The suite of Open eVision 3D libraries can handle the rendering of data sourced from various brands and types of 3D sensors, while the Easy3D foundation library generates 3D representations that can be quickly processed for interactive display using the 3DViewer. The software can also facilitate measurements of entire scenes or specific objects within them via Easy3DObject, as well as comparison and validation against a reference using Easy3DMatch.

IDS has developed and produced products for industrial image processing since 1997. The company’s Ensenso 3D cameras were designed to provide a solution for 3D image capture that is precise, quick, and cost-efficient. Ensenso N, C, X and XR cameras work according to the stereo vision principle, while the Ensenso S series uses an alternative 3D method with structured laser light, which enables a more compact camera design. The latest model is Ensenso C, a stereo vision camera that generates 3D point clouds and 2D colour (RGB) images, thanks to an additionally integrated image sensor.

Euresys: Featured 3D vision product

Euresys’ software tools address the various challenges of evaluating and prototyping 3D vision applications.

A bundle of Open eVision 3D libraries manages the rendering of data coming directly from multiple 3D sensors, brands and types (e.g. Depth Maps, Point Clouds, Zmaps). The resulting 3D representations produced by the Easy3D foundation library are then processed for a fast and interactive display (3DViewer), Measurements of the whole or specific objects in it (Easy3DObject) or comparison and validation compared to a reference (Easy3DMatch).

A specific solution is also provided for the extraction of 3D information from a laser line setup. Euresys Easy3DLaserLine provides the necessary functions to implement a high-precision calibrated single or dual laser line triangulation setup. Open eVision 3D Studio (a free tool) drastically simplifies the configuration of single and dual 3D laser line inspection systems using the Coaxlink Quad 3D-LLE frame grabber, as well as the Easy3D and Easy3DLaserLine libraries.
