Study on the Accident Characteristic Code of Explosion in Work Site

摘要：

Destructiveness of explosion in work site is closely concerned with some factors of surrounding media, such as the direction, the position, the criticality and so on. Firstly, characteristic information of the original picture before the accident is restructured according to the obvious characteristic of explosion image in some direction and position. Then, because of the invariant property of accident characteristic in the aspects of direction, position and attribute, more rudimental information in the explosion image is explored, classified, screened, adjusted, combined and disposed, and thus the optimal direction and position of the superposition characteristic is achieved. Based on statistic characteristic information of the scene of accident image, the authors use accident standard data structure spectrum r(s), O(s), q(s), ∈(s) to select characteristic information, extract effectual accident characteristic information from massive possible information, adopt Huffman coding system to simulate it on the computer, compare pictures taken before and after the accident, and hence, reveal the true cause of accident and provide a new approach to the investigation of accident.
