METHOD AND ARRANGEMENTS FOR PROVIDING INTENSITY PEAK POSITION IN IMAGE DATA FROM LIGHT TRIANGULATION IN A THREE-DIMENSIONAL IMAGING SYSTEM

Provision of a position of an intensity peak in image data produced by an image sensor in response to light sensed by the image sensor after the light has reflected on an object as part of light triangulation performed in a three-dimensional imaging system. Devices are configured to obtain the image data and determine which of first and other, second, peak characteristics that the intensity peak is associated with. The position is provided according to a first computing algorithm if the intensity peak is associated with the first peak characteristics and according to a different, second computing algorithm if the intensity peak is associated with the second peak characteristics.
