HyperSpectral Imaging (HSI) is an emerging imaging and spectroscopy technology that generates a spatial map of spectral variations of the captured object.
HyperSpectral Imaging (HSI) is an emerging imaging and spectroscopy technology that generates a spatial map of spectral variations of the captured object. It maps the intensity of the reflected light from the surface of the sample at well-defined optical wavelengths.
The advantages of HSI include:
- Non-invasive technique.
- Simultaneous spatial and spectral information.
- Fast to generate a big amount of rich information data.
Engineers build hyperspectral sensors and processing systems for applications in astronomy, agriculture, biomedical imaging, geosciences, physics, and surveillance.
HyperSpectral Imaging (HSI) is a challenging technology and requires a solid knowledge of the system configuration in order to capture quality images. SOLPI can offer its expertise in the field and help other companies in the development of state-of-the-art hyperspectral applications.
HSI, as any emerging technology, do not have many support tools to help new users. It is not easy to get standardized hyperspectral data out of the camera’s sensor and to facilitate the process, SOLPI has developed the HyperSpectral SDK.
HyperSpectral SDK works with two branches of hyperspectral sensors, push broom scanner and snapshot mosaic sensors. The former scans the object of interest over time, the so-called line-scan, and the latter can generate a hyperspectral image in a single shot, enabling video frame rates.
SOLPI offers support in the design of the hyperspectral system configuration. We can provide:
- The hyperspectral camera that meets the application requirements.
- Test benches: versatile structures to place the camera using different angles and distances from the scanning object.
- High precision conveyor belts to scan the targets.
- Custom lighting setups well defined for the wavelengths of interest.
- The suitable lens and bandpass filters for the selected hyperspectral camera and application.
- The most suitable software tools to develop the application efficiently.
- Reference targets for calibration of the hyperspectral system.
SOLPI offers the possibility to perform feasibility studies to newcomers in hyperspectral imaging:
- Select the spectral bands of interest.
- Choose the lighting configuration for your application.
- Help the user in the calibration of the hyperspectral system.
- Offer support in the design of the hyperspectral application.
- Help to develop the better model to sort or analyze the hyperspectral data.

Summarizing, SOLPI can provide the following elements for 3D Triangulation:
- Vision components, such as cameras and lenses.
- Mechanical components, such as conveyor belt and structure to assemble all the vision components.
- Software to generate the 3D profiles and range maps.
- Consultancy services and trainings.
