Production
quality controlSoftware for controlling the presence and color quality of machine painted spots, used to identify car springs in their assembly. Involves:
- Verification of the correct positioning of the paint spots on a helical surface.
- Classification of the springs by absence or presence of the paint spots on specific coils of the spring.
Analyse
and control of LEDsAnalyse color of the electro luminescent diodes and interpretation of the results from a CIE chromaticity diagram.
- Detecting the RGB color intensities.
- Conversion of RGB values to CIE coordinates.
- Production of the results in a CIE diagram.
- Automatic control of camera (black/white balance, shutter speed, gain...).
Crash
test analysis
Vision techniques applied to the analysis of movement. Involves:
- Creating marking vectors and tracking them over a sequence of images.
- Automatic tracking and shape recognition of objects in the image (pattern
matching).
- Option to predict movement of objects by theoretical calculation of
trajectory.
- Option to save a sequence, with its markers, in a AVI file format.
Saving the results in graph or table format to EXCEL (velocity,
acceleration, trajectory...).
- Supporting specialized outputs from high speed cameras.
Inspection
of Liquid Crystal Display screensTest and control of cellular phone LCD screens. Involves:
- Detection of faulty inclination of the screen.
- Detection of faulty pixels (checkerboard test).
- Detection of icons.
- Detection of manufacturers' logo.
- Measurement of backlighting.
- Measurelent of contrast.
- Validation of the casing color.
- Validation of the quality of color printed patterns (hang up = red, dial = green...).
Control paper print qualityAnalyse the quality of paper print, involves:
- Determining the coefficient of ink smudging.
- Determining the color fusion coefficient.
- Determining the print precision.
Guiding
system for heat scalant robotComputer controlled vision system to guide robot in heat seal flexible connectors, involves:
- Detecting the two elements to be sealed with high precision.
- Guiding the motor to correctly align the two elements.
Detection of impurities in electrical insulation materialQuality control of plastic strips samples used in fabrication of high tension electric cable, involves:

Controlling
correct assembly of electronic board componentsOn-line verification of the presence, position and orientation of electronic components that are recognised by their shape, involves:
- Learning from a master reference board.
- Detection being invariant of position, ange of rotation, and magnification of the board image.
- Detection being robust to lighting variations.
Certification
of laser beam characteristicsReal time control and diagnostic of laser beam characteristics, involves:
- Profiling of user defined and automatically determined axes.
- Fitting polynomial curves to the laser beam profiles.
- Calculation of the center of energy intensity.
