摘要
为解决视觉导航数据量大,计算周期长,与其他导航方式进行组合导航时存在信息滞后的问题,借鉴矩阵式二维码设计思想设计了一种可用于视觉导航快速识别的路标,并基于此路标特征提出一套快速识别方法。进行动态识别实验验证该快速识别方法,实验结果表明,所设计路标及提出的快速识别方法可以实现快速识别,满足视觉导航实时性要求,在采集图像畸变严重或路标只是部分进入视场等导致无法解码的情况下,系统依然可以输出部分导航信息。
To solve the problems of large data size and long computation period of vision navigation,and information postponement when the combined navigation is integrated with other navigation modes,a landmark for vision navigation fast recognition was designed according to the design thought of matrix two-dimensional code. On the basis of the landmark characteristic,a landmark quick recognition method is proposed. The experiment of dynamic identification is carried out to verify the validity of the fast recognition method. The experimental results indicate that the landmark and fast recognition method can realize the recognition quickly,satisy the real-time requirement of vision navigation,and the system can also output the part navigation information in the case of decoding failure because of serious distortion of the collected image and part landmark entering into the field of view.
