摘　　要：在引入互补折反射全景装置结构基础上,对内外环互补折反射柱面全景图像对应点存在差异的原因进行了详细分析。针对两幅图像间对应点坐标差异,研究了用Harris角点配准方法寻找配准变换模型的方案,以解决互补折反射柱面全景图像对的配准问题。实验分别给出了使用仿射、投影、多项式变换模型的配准结果及精度,表明三次多项式模型具有更好的适用性。Based on the introduction of the complementary catadioptric omnidirectional imaging system, the difference between correspondence points in two complementary cylindrical panoramic images was analyzed in detail. For the coordinate difference of correspondence points in two images, Harris comer was chosen to search transform model of registration, to solve the registration problem of the two complementary cylindrical panoramic images. The experimental resuhs cover the registration results, precision of using affine model, projective model and polynomial model for registration, which suggest that third-order polynomials model is more suitable.
