| 摘 要： | 提出了一种基于RGB三色差的彩色图像中消防水炮射流轨迹的提取算法。首先在已知射流起点情况下向四周进行24个方向的扫描,确定射流的方向为米字形的8个方向之一,然后在此方向上执行双线扫描探测,直到满足某一阈值条件或到达图像的边界。实验结果表明,该算法在复杂背景下能准确完整地提取消防炮射流轨迹,算法的适应性较强。

| Abstract: | An extraction algorithm for the fire cannon＇s jet trajectory in colorful pictures based on the difference of RGB is presented.First,24 directions are scanned under the condition that the start of jet is known to make sure that the jet is in one of the 8 directions of the 米 shape,and then the direction is detected by the two-trace method until a certain threshold condition or the edge of the picture is reached.The result shows that this algorithm can extract fire cannon＇s jet trajectory accurately and completely even under complex conditions.The algorithm is strongly adaptive. |
