Flow visualization measurement has been making use of measuring flow velocity in many fields. As in case of internal combution engine, gas flow in the engine deeply influences on combustion and heat transmission. The authors realized the flow visualization method using color layer, which can indicate the velocity to the depth direction of the image by color, and then three-dimensional measurement can be achieved. This paper shows the problems and solutions as to apply flow visualization by color layer to air flow measurement. One is the fabrication of trace particle being suitable for the color layer visualization. Another is obtaining the exact color information by solving the problems which happen as using a small tracer particle, and improving the method of image-processing. As a result, this newly revised visualization method make it possible to measure velocity of the particle within the error of 10%.
