Abstract:
1. A process for checking the quality of a log, the log having a front surface surrounded by a front surface perimeter, a rear surface surrounded by a rear surface perimeter, and a lateral surface, the lateral surface being the surface of the log between the front surface perimeter and the rear surface perimeter, the lateral surface having a substantially curved shape of a log, the quality check being carried out via a visual examination of the outer appearance of the log, characterised in that the process comprises the operating steps of: (a) obtaining a first flat photographic representation, representing the flat extension of the whole lateral surface of the log and in which every point is presented as it would be presented if seen on the log from a viewpoint positioned outside the log along a direction which extends radially from the log and passes through the point, said first flat photographic representation having been obtained via use of one or more cameras; and (b) evaluating the quality of the log by examining the first photographic representation.
