Laser triangulation
In our scanners, we include dimensional scanning from laser triangulation to digitalize complex 3D shapes, such as the geometry of logs and lumber. The data obtained is used to calculate precise measurements of diameter, length, curvature and taper. Laser triangulation is obtained by pairing a laser source and a camera pointing to an object with a fixed relative angle. Exploiting the reflectance of the laser light on the object surface, the relative distance is calculated using trigonometry.
Stereoscopy
Binocular vision is the type of vision that enables the three-dimensional perception of the surrounding environment. Stereoscopic imaging is the digital equivalent of binocular vision, where depth is reconstructed by combining a pair of images of the same scene taken from a slightly different point of view. MiCROTEC scanners use stereoscopy to obtain a digital reconstruction of three-dimensional scenes and objects.
Hyperspectral Imaging
The human retina collects color information by combining light intensity in three spectral bands, centered respectively in the red, green and blue (RGB) bands of the electromagnetic spectrum. Color representation in the digital world also follows this principle, and in most applications, color images are recorded using a camera that measures color as a linear combination of the same three basic colors (trichromacy or RGB imaging). Naturally, monitors and displays are RGB as well. When it is necessary to record color information more precisely, or if there is a need for higher spectral resolution, we use our proprietary hyperspectral camera to collect color information over hundreds of spectral bands.
