In this paper, the formation and development of debris cloud formed by impact with high speed by using image processing technology were researched. How to obtain the debris cloud images at different moments by high-energy pulsed X-ray imaging technology, the measurement method of the main parameters of debris cloud, the processing of debris cloud image process and pro-cessing results were introduced. The motions parameters such as development of debris cloud patterns, the speed and spray angle were achieved. The image processing technology was used to achieve the measurement of two key parameters of the debris cloud, the speed of the debris cloud and jet angle versus time curve.
