Abstract: The present invention relates to a method for measuring cracks remotely and the device thereof. First, multiple laser spots with known a shape are projected onto a remote wall and beside a crack. Then, by using geometric calculations, the relative coordinates of the laser spots on the wail and the real distance can be given and used as the reference length of the crack. Next, a camera is used for taking a picture of the remote crack along with the laser spots; the image identification technology is used for calculating the relevant parameters of the crack. Thereby, to acquire the parameters of the crack, a user needs not to be present at the site for measuring at a short distance or placing a reference object, and thus providing safety and convenience.

Abstract: The present invention provides a method of mobile image identification for flow velocity and the apparatus thereof. The present invention integrates laser-light module and mobile photographing devices such as smartphones, cameras, or tablet computers. After multiple laser spots are projected on the surface of flowing water, water-surface images including the laser spots are photographed continuously. Then the software program of image identification in the mobile photographing device performs calculations and coordinate conversion. According to the difference between multiple water-surface images taken continuously, the flow-velocity information of the water surface is given.
