Abstract: A system of computing surface reconstruction, in-plane and out-of-plane displacements and strain distribution utilizes the optical switching element to switch the reference beam to analyze the images of the test object before and after deformation, to measure the topography, in-plane and out-of-plane displacements and surface two-dimensional strain distribution on the test surface of the test object, and thus to increase the measurement range on the test surface of the test object with the use of image registration. Thereby, the complexity and error of scanning the test object can be reduced. Such a system need not to move the image capturing device or test object to generate relative displacement for reaching the measurement effect of the test surface of the test object in three-dimensional coordinates.

Abstract: The present invention discloses a method of determining a whole-scene image by using multiple image-capturing devices, and the method has two main features including non-contact formation digital image method and the parallax elimination process for captured images. The former feature uses a concyclic fitting calculation to easily determine the locations and orientations of the image-capturing devices, so as to achieve the objective of assisting in capturing the whole-scene image. The latter feature can effectively improve the image quality, so as to effectively solve the problems in conventional technology.

Abstract: An image correlation for images having speckle pattern is evaluated. Modulation transfer function (MTF) curves of speckle-pattern images captured at different times are figured out. Whether a correlation value between the MTF curves meets a threshold is checked. If the correlation value is smaller than the threshold, speckle-pattern images are re-selected for re-figuring out the MTF curves and the correlation value. Thus, error of strain and displacement for digital image correlation owing to blurring images of the on-moving target object is figured out; calculation time of the digital image correlation is reduced; and accuracy on measuring physical parameters of the target object before and after movement is improved for digital image correlation.
