拟合人眼视觉机制提出了非均匀光照下指针仪表图像的预处理算法,在此基础上进一步设计了座舱指针式仪表自动判读算法。首先对仪表盘图像进行亮度均衡、二值化变换,再将指针细化,然后根据改进的Hough变换提取目标信息,确定座舱指针式仪表的读数。实验结果表明,该算法有效地解决了在非均匀光照情况下的飞机座舱指针式仪表自动判读,降低了判读误差。

the human visual mechanism , based on that we further design the automatic interpretation algorithm for cockpit pointer instruments .Firstly the algorithm conducts the lightness balance and binarisation transform on instruments panel images , and then makes the pointer needles thinning down;afterwards , it extracts the object information according to the modified Hough transformation and determines the readings of cockpit index instruments.Experimental results prove that the algorithm effectively solves the issue of automatic interpretation of cockpit pointer instruments in circumstance of non-uniform lightness , reduces the reading error .
