| 中文摘要: |
| 针对机器视觉动态测量中编码点的使用需求，
提出了一种基于频率编码的动态编码点。
在测量过程中，动态编码点按照固定的频率闪烁，
将编码点的闪烁频率作为编码信息。
动态编码点由静态定位区与动态编码区组成，
其中，静态定位区用于对动态编码点特征圆的识别与定位，
编码点的编码信息储存在动态编码区中。
根据动态编码点的结构，设计了编码点的检测与解码算法，
实现了动态编码点的快速检测。编码点提取实验结果表明，
动态编码点编码方案简便稳定，便于布置，易于检测和识别，
满足设计要求。 |

| A dynamic encoded
target based on
stroboscopic
information is
proposed for
meeting the demand of coded targets in the dynamic measurement of machine vision.The dynamic encoded targets flicker according to the fixed frequency in the measurement.The flicker frequency of targets are used to encode information.The dynamic encoded targets consist of static location features and dynamic coding features.The static location features is used to recognize the position of dynamic encoded targets.The coded information is stored in the dynamic coded features.The detection and decoding algorithm of dynamic encoded targets are designed based on the dynamic coding structure to realize rapid recognition of targets.The experimental results of the extraction of dynamic encoded targets show that the proposed targets with dynamic coding information can be steadily extracted and they are easy to arrange and identify.Thus,the dynamic encoded targets can satisfy the requirements of dynamic visual measurement. |
