3D Acquisition Technologies
The main objective of 3D acquisition equipment is to generate a cloud of points with the information of the scene. This can be treated with specific software tools or used to generate a depth map and apply conventional 2D vision algorithms.
Cycle time? Occlusions? Catch without movement?
The application of technology will vary according to need and will be key to further analysis.
Laser profilometry
High-speed 3D linear acquisition technology - acquire thousands of profiles per second!
Fringe projection
Acquisition of the scene with high accuracy and resolution, in a single capture!
Stereo vision
Obtaining three-dimensional information by comparing images obtained with multiple cameras.
Time of flight
3D reconstruction from the speed of reflected radiation from the projection of an infrared beam.
A pattern-based behavior...
Sensors based on FRINGE PROJECTION technology acquire the scene without the need to move the piece or the sensor.
This technology is based on the emission of multiple lighting patterns to obtain three-dimensional information from their projections.
High resolution and accuracy is achieved in record acquisition time, thanks to the high computing power provided by the graphics processing units (GPUs) integrated into the sensor.
Acquisition of the scene
The use of this technology allows us to obtain a high-precision, information-rich point cloud. The occlusions generated by other linear customs technologies are eliminated.
High-level processing
Not one, not two, not eight.... Dozens of cores processing on the built-in GPU!
Acquisition of scenes with fields of view up to 3m in record time.
Laser profilometry
3D acquisition at high speed of movement
The systems based on 3D laser profilometry incorporate a linear laser to obtain the information through a CMOS camera.
The scene is captured using profiles, which requires linear lighting, allowing the illuminator's power to be concentrated in a very small area, reaching capture speeds of several thousand profiles per second.
Stereo vision
Robustness in the face of environmental changes in the scene!
Machine vision stereo emulates the behavior of human vision, generating a three-dimensional model by comparing two or more images obtained through cameras that make up a calibrated system.
The use of structured lighting in stereo vision systems, allows to obtain an unchanging 3D information in case of a variation of positioning or of different reflections of the material.
ToF flight time
Time of Flight (ToF) acquisition devices integrate an infrared projection source and generate 3D information from the time elapsed between the projection and the capture of the reflection produced.

Applied technology
Bin picking
High precision 3D object positioning!
Taking objects of different geometries and positions from a container?
A combination of precise and fast machine vision algorithms, combined with an optimal design of the robot cell, is necessary to achieve success in this type of application.
We provide Bin Picking solutions with different 3D acquisition technologies, studying the most suitable solution for each case.
