Correlation Velocity Measurement Technology Based on Linear CCD

To measure the velocity with high precision, the correlation velocity measurement technology based on linear CCD is developed in this paper. The displacement of moving object between two adjacent moments is measured by detecting light intensity of the light-emitting particles from the surface of moving object. Then the velocity of the moving object can easily be calculated. Simulations are conducted to measure the velocity of the moving object in uniform linear motion under ideal conditions. On the basis of the principle of correlation velocity measurement, the velocity which is measured makes a comparison with its actual velocity of the moving object. The results show that the proposed method of velocity measurement has the advantages of high precision and wide range to meet the requirements for velocity measurement of the vehicles.
