  • Publication number: 20140368638
    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.

  • Patent number: 8908195
    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 wall 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.

  • Patent number: 8558881
    Abstract: A telescopic probe monitoring system for riverbed elevation monitoring at a bridge pier is revealed. The system includes a measurement module for measuring riverbed elevation under water and a control module. The measurement module includes a housing, a multi-layer tube, a driving member with scales, a photographic unit for capturing images, and a sensing unit. The control module controls the driving member to extend the multi-layer tube. Thus the sensing unit on the bottom of the multi-layer tube contacts the riverbed and then sends a sensing signal to the control module for stopping pushing the multi-layer tube and controlling the photographic unit to capture images of the driving member. According to the images and movement of the measurement module, the control module learns the riverbed elevation and sends the riverbed elevation to a remote monitor unit for real-time monitoring of the riverbed elevation.

  • Patent number: 8352213
    Abstract: A probe monitoring system for riverbed elevation monitoring at bridge piers is revealed. The system includes a housing, a measuring rod, a moving member, a control module, a photographic unit and a sensing unit. The housing is fixed on the pier. Both the moving member for driving the measuring rod and the control module for control of the moving member are mounted in the housing. When the control module drives the measuring rod to move downward and the sensing unit on the bottom of the measuring rod approaches the riverbed, a sensing signal is sent to the control module. Thus the moving member stops moving the measuring rod and the photographic unit takes pictures of the measuring rod to generate an image. Then the riverbed elevation is obtained according to the image or the movement of the moving member and is sent to a remote monitor unit for real-time monitoring.
