Abstract
The present study has developed a remote crack-measuring device using an Android camera with the laser-positioning technique. Four laser points projecting on walls along with cracks are photographed and utilized as reference points to process the image ortho-rectification. Then, for the crack recognition, a crack-tracking method based on the edge-detecting algorithm is used and implemented in the system. Finally, a field experiment was conducted to validate the proposed remote crack-measuring system. The preliminary result shows that this system has a great potential for field applications.
