摘　　要：建立了姿态角误差分布的正态概率模型,深入研究了姿态角误差在陆地自主车三维视觉处理中的传播特性.结果表明,当陆地自主车俯仰角或侧滚角不为零时。The normal distribution of the attitude angles is presented and the propagation of their errors in coordinate transformation in autonomous land vehicle(ALV) is analyzed. The results indicate that the errors of the attitude angles affect the coordinate transformation significantly when the pitch angle or roll angle of the three attitude angles is not zero for the ALV which travels on outdoor environment.
