- W2352805574 abstract "Method for analysing the ballistic trajectory of the ballistic missile at the vertical-flying-off stage is presented. The serial infrared images are obtained on condition that thermal imaging system is static and the ballistic missile is taking off. Image noise is removed by SUSAN filtering and the gray threshold value which is regarded as the lower limit of the windowing transformation of gray is confirmed using iterative method in order to segment image and to obtain the coordinates of the target centroid. The flying height of the target at any moment can be acquired by proportion mapping according to the positional alteration of the centroid frame to frame in the serial infrared images. The parameters of the ballistic model are done on the basis of the math model built, by the non-linear regression method and matrix theory, using VC++ 6.0 and Matlab 6.5. This measurement method which is in the complete visual field is untouched, and its measuring accuracy is high, so is its automaticity." @default.
