A method to measure the deformation and fracture of fibers on the fracture surfaces of fiber reinforced composite (FRC) is developed by reconstructing a 3-D image from a stereograph. The method proposed in this article integrates image processing techniques of thresholding, vectorization, matching, and 3-D analysis. The accuracy of the measured result obtained by this method is evaluated by the comparison between the calculated fiber length and the real length, calculated with the help of a micrometer caliper. From the comparison, it is confirmed that the fiber length is calculated with high accuracy, if the occlusion problem does not occur.
