Abstract

In this paper, a preliminary study on the development of a wireless image-based sensor for two-dimensional (2D) crack propagation monitoring is reported. This sensor contains an optical navigation sensor board (ADNS-9500) which is incorporated into the Imote2 IPR2400 platform. To monitor crack propagation, the Imote2 sends a signal to the ADNS-9500 to switch on the built-in laser and camera collecting images reflected from the concrete surface. The captured images are processed by an optical flow method to obtain the relative displacement between images. A series of tests have been conducted to calibrate the accuracy of the proposed crack sensor. Results show that the crack sensor exhibits a strong linearity under 2D movement and can track the movement quiet well.
