Simple methods using the striped pattern paper marker and FFT (fast Fourier transformation) have been proposed as alternatives to measuring the optical density for determining the level of bacterial growth. The marker-based method can be easily automated, but due to image-processing-base of the method, the presence of light or the color of the culture broth(More)
Inspection of the structural health of the bridge column is very important task but near-water surface region is dangerous for structural health monitoring robots due to water tides and spray. The unmanned surface vehicle with vertical thrusting function was developed to attach bridge column regardless of the surface status or material for close inspection(More)
This research presents preliminary results of developing aerial imaging platform for disaster site surveillance. The Can-Satellite (CanSat) less than a 700g weight equipped with an RGB camera and a forward looking infrared (FLIR) camera which can be launched with the rockets, drones, or balloons was developed. Additional flight sensors and network(More)
