Standalone Image Processing

Embedded Machine Vision Systems

At Qtechnology, we customise advanced computer vision solutions, which are based on our smart camera modules, with exchangeable camera heads, designed in-house to fit each customer’s specific needs. In contrast to generic stand-alone smart cameras, our smart cameras perform image-processing directly in the camera. A major benefit is the ability to run as a complete standalone image-processing system, without the need for an external PC or other product integration.

Our camera platform has Gigabit Ethernet connections, display interfaces, display port or HDMI, USB ports and Cfast card interface or similar. By connecting a screen, keyboard, and mouse to the camera you will have a full computer available.

All cameras are running GNU/Linux, a secure and stable environment and further, it provides access to several open-source libraries and applications for image processing and application development as well as third-party libraries supporting V4L2 API.

The Ability to See Beyond the Visible

We are developing computer vision solutions with a range of different imaging technologies, with an analysis range across the electromagnetic spectrum. Our solutions are not restricted to simply analysing the portion of the electromagnetic spectrum that is visually perceivable by humans, as we are also providing infrared, ultraviolet and x-ray imaging technology.

Infrared Imaging
NIR Near-Infrared Imaging 650 – 950 nm

By replacing infrared filtering in the cameras and the use of NIR enhanced image sensors, our cameras can be used for NIR imaging.

Applications: Surveillance, hyperspectral imaging, bottle inspection, industrial sorting, agriculture, etc.

SWIR Short Wave InfraRed Imaging 900 – 1700 nm.

With special inGaAs sensors, the Near-infrared imaging spectrum can be increased to cover up to 1700 nm.

Applications: Our cameras using InGaAs sensors can be used for hyperspectral imaging, spectroscopy, biological imaging, water/moisture detection, industrial sorting, Internal defects, etc.

LWIR Long Wave InfraRed imaging 8 – 14 um

LWIR apply uncooled microbolometer sensors used for industrial thermal imaging.

Applications: building inspection, industrial insurance inspection, industrial process control, etc.

Visible Light
Standard Imaging

Different coloured LED modules or combinations can be customised to each application.

Many applications require very specific light wavelengths to emphasise only certain specific features of the object. If the color of the feature of interest is known, using a similar wavelength of color LED will highlight this specific feature. For instance, green light makes green features appear brighter while red light will make green features appear darker.

Applications: Used in the majority of vision applications. In particular, in applications where color is an important characteristic.

Ultraviolet Imaging
UV Imaging 200 – 400 nm

With the use of Special UV enhanced BSI (Back Side Illuminated) sensors, our cameras can be used for reflected-UV imaging and UV Fluorescence imaging.

Applications: Forensics, detecting scratches and digs on specular surfaces, detecting changes in surface texture on smooth surfaces, detection of organic materials eg. for foreign object detection or oils, grease contamination on surfaces

X-ray Imaging
X-ray Imaging

By combining our low noise image sensors with scintillators, our cameras can be used in x-ray various applications.

Applications: Detection of metal, internal damages, hidden components, cracks, welding flaws, and determination of dimensional measurement, etc.

Multiple Wavelength Imaging

The Electromagnetic Spectrum

Hyperspectral Imaging solutions

With the use of low noise sensors, with spectrographs or specialised sensors, with narrow-band spectral filters at the pixel level, hyperspectral image cubes can be captured. These cubes can be used for spectroscopy to identify spectral features and signatures of different materials. It is not only used to separate specific materials but also to make qualitative measurements of the analysed objects.

See our jelly Bean experiment for information regarding the application of hyperspectral imaging in food inspection.

Multispectral Imaging solutions

Some computer vision solution requires our multi-spectral or hyperspectral imaging technology.

Multispectral imaging is a combination of a few bands of the spectra at the pixel level. An example is our 3 CCD camera where each colour spectra are optically separated in red, green and blue and recorded at pixel level on three CCDs one per colour.

See a case in which our spectral cameras has been used to distinguish and sort different types of plastics.

Research & Development

With our internal electronics design, software development VHDL and mechanical design, we control the entire design cycle in the development of new camera platforms and sensor integration. Beyond the development of camera systems, we have access to a broad range of in-house research facilities for optical, chemical and mechanical research, design and integration.

We transfer our specialised knowledge about optical design into the development of specialised optics, lenses, lighting, etc. When designing complex optical systems, we can adjust the system to our clients’ specific system needs and requirements.

Exploiting our state-of-the-art research facilities, we can perform chemical testing and verification of product substances to ensure a reliable vision system. We can evaluate systems in several conditions and observe its behaviour, as well as making sure the system will not misbehave under various circumstances.

We are also able to develop the mechanical design for camera enclosures, specialised sensor integrations, machines and micromechanics (e.g. lenses, gears, etc.)

Finally, Qtechnology has a big network of suppliers for electronics and mechanical manufacturing of parts for both cameras and machines.
