摘要
在射影几何的基础上描述了一个摄像机及成像系统的模型,给出了模型参数的两种计算方法。该方法已用于一个三眼立体视觉系统摄像机及成像系统模型参数的计算,所得参数用于三维坐标的计算,最大相对误差小于3.4%。该模型适用于类似成像系统的校正、反透视投影、2.5维及3维信息的计算。
Descriptions are given on the basis of projective geometry of a model of video camera and imaging system. The algorithms have been used in a trinocular stereo vision system to calculate thd model parameters of the cameras, and the parameters thus obtained have been used to calculate the three dimensional coordinaters of a scenes with the maximum of relative error being smaller than 3. 4%. The model and algorithms apply to similar imaging systems, and may be used in the calibration of imaging systems, inverse perspective, and calculation of 2.5 D and 3 D information.
