摘　　要：传统的灰度编码标志依据自身的几何及结构关系来识别编码,往往由于倾角、畸变大而识别错误;而彩色编码标志虽然增加了颜色信息,但是结构又相对复杂,也存在算法复杂、识别率较低的问题。针对上述问题,本文将标志中的颜色信息与几何信息相结合,设计了一套简单、实用且可靠性更好的彩色点分布型编码标志。该编码标志利用标志点的颜色信息能够有效简化编码标志的解码步骤,提高标志识别效率,并且能够增加编码数目。实验结果表明,该方法实现容易、识别率高,具有一定的实用价值。The code of the traditional gray coded targets are always identified through the relation of their own geometry and structure,but there is often misidentified in case of big inclination angle or camera distortion.Although the color coded targets gain more color information,their structure are relatively complex,and there are the problem of complex algorithm and low recognition rate.Aiming at the existing problem,in the thesis a set of color point distribution coded target was designed by combining color information with geometry information,which is simple,utility and reliability.It does not only simply the decoding procedure of coded target by utilizing the color information,but also highly improve the recognition rate,the positioning accuracy and increase the code number.Experimental results indicated that this method could be implemented easily with high recognition rate and has some utility value.
