Abstract

PURPOSE:To shorten the time required for image analytic processing by recording a mark previously at a road surface part where a defect occurs and performing the image analytic processing only for data on the road surface where the mark is extracted. CONSTITUTION:When the state of a crack is investigated preliminarily, a marking car 10 records mark data at a roadside part. Then a road surface property measuring car 20 is run at the time of actual measurement and the data on the road surface where the mark data is recorded is recorded on a video tape 28. The road surface data is stored in the image memory 32 of the automatic analyzing device thereafter and read out by a controller 36 to analyze the crack automatically by the image processing. At this time, the controller 36 extracts and recognizes the cracking mark and performs the analytic processing only for the data on the road surface where the there is the crack actually.
