Real-time Shape Measurement of a Moving/Deforming Object
We have described a time-sequential highframe-rate shape measurement system for moving and deforming objects. The system is based on multi-spot projection measurement in a single image using a high-speed vision with a co-processor for numerous-point analysis. We demonstrated a throughput of 955 fps and a latency of 4.5 ms. Experimental results for three kinds of objects showed that the objects were measured correctly.
This type of measurement system is expected to find uses particularly in feedback applications such as robotic manipulation, automobile application, surgery support, inspection, human-machine interfaces, and so on.
