Реферат: Data indicating cracks detected on the road surface are recognized in an automatic manner using a computer (4). The image memory storing the data of road surface is divided into a plurality of regions. Some of these regions data indicating a crack (LP), and any one of them can be a starting point of tracing. A line segment (SG) corresponding to the crack (LP) is extracted from a starting region. The next tracing direction is determined based on the direction of line () of the extracted line segment (SG), and it is determined whether a crack (LP) exists in the neighboring region in the direction of tracing. Segments (SG) are extracted only from the regions that have been found to contain cracks (LP). This procedure is started at each starting point and repeated until the tracing is finished. Thus, crack data in the image memory are extracted as combinations of line segments (SG). In this method, segments are not necessarily extracted from all of the regions, and consequently the processing speed is increased.
