[0036] The present invention will be further described below in conjunction with the drawings.
[0037] Combine Figure 1~3 The steps of the road crack detection technology based on image analysis proposed by the present invention are as follows:
[0038] Step 1: Equipment installation and image acquisition
[0039] Because road cracks are generally small, each crack has fewer pixels in the width range. In order to meet the requirements of crack width recognition accuracy, the invention uses a camera with a resolution of 2048*1536. Increased the number of pixels occupied by the crack in the image , Avoid scaling images to ensure that each photo has the same resolution (the actual geometric size of a unit pixel).
[0040] At the same time, in order to determine the resolution of the crack image, the actual geometric size of the image must be calibrated. The shooting requirements for calibration are the same as on-site collection. The specific calibration method is to select a flat grou...
