An orientation measurement method which used auxiliary recording instruments was developed to enhance applicability and operating efficiency of the Large Scale Particle Image Velocimetry (LSPIV) and the Spatio-Temporal Image Velocimetry (STIV), the non-contact current measurement methods which applied image analysis techniques. The method allows a video camera to obtain necessary parameters using the conventional orientation method which requires predetermined control points at an observation site.

With this method, field observations can be carried out without the reference marks at the time of observation, consequently saving the efforts of orientation measurement.

Key Words:non-contact current measurement,LSPIV,STIV, river surface flow
