LSPIV
smartphone
ortho-rectification
A mobile system for LSPIV (large-scale particle image velocimetry) measurement is developed. The system consists of commercially available smartphone device and LSPIV application software. The software utilizes a camera and other sensors embedded in the smartphone. The image captured by the camera is automatically ortho-rectified with support from positional information obtained by the sensors, then velocity distribution is estimated at every moment. The performance of the developed system is verified through a rotating image test. An acceptably small systematic error and substantial magnitude of instantaneous velocity error are confirmed, and countermeasure for this errors is pointed-out.
