| Abstract: | The maximum altitude of a flare is an important indicator of its quality.A better accuracy of the dynamic measurement results of the flight parameters could be provided from a proper signal flare spot locating method in optical measurements.In this paper,a signal flare spot center location method based on Gaussian fitting is proposed.An improved region growing algorithm is used to segment the area of flare,and the exact position of signal flare spot is located using Gaussian curved face fitting,which can achieve sub pixel accuracy while computing speed.The experimental results show that the error of this method is less than 0.4 pixels,and it has good stability and versatility. |
