基于图像处理技术的降落伞充气时间测试方法

Based on Image Processing Technology Parachute System Aeration Time Judgment Method

依据图像测量技术,利用图像处理计算软件计算出降落伞伞衣在充气展开过程中的投影面积,通过与标准伞投影面积相比较得到符合判定依据的最后张满点,从而自动精确地判定出降落伞伞衣在充气展开过程中的张满点并计算出充气时间,减少试验过程中的人为误差。

Based on image measurement technology, the projection area in the inflatable parachute process was calculated by using image processing software. Compared with the standard parachute projection area, the filled point of parachute is got consistent with decision basis. The filled point was judged in inflatable parachute process and parachute aeration time was calculated to reduce the human error in the test process.
