摘要
对传统的基于图像处理技术自动报靶系统进行分析,针对传统靶面环线识别比较困难的缺点,提出了一种新的基于点控制的自动报靶系统。该系统采用具有已知半径的点作为靶面图像的控制点,降低了系统对图像质量的要求,采用简单的阈值即可实现点的分割,大大减小了图像的预处理工作。针对点控制,提出了距离加权平均法来计算靶数,避免了繁琐的图像几何校正工作,同时保证了报靶精度。
The traditional automatic target record system based on image processing is analyzed, which has difficulty with ring recognition. An automatic target record system based on point control is proposed. Control points with given radiuses are adopted in this system so that the requirement of the system on image quality is lowered. Point segmentation can be realized only by simple threshold segmentation, so the work of image preprocessing is greatly reduced. On the basis of the point control, the distance weighted average method is applied to determine the shooting score. The method avoids complicated image geometric correction and ensures the precision of the target record.
