The computation of a mobile robot position and orientation is a common task in the area of computing vision and image processing. For a successful application, it is important that the position and orientation of a mobile robot must be determined properly. In this paper, a simple procedure for determining the orientation of the mobile robot using two cameras is presented. The two cameras are used to capture the images of a mobile robot at various orientations. Four simple neural network models are developed to associate the inputs and output (orientation). First neural network model is used to estimate the orientation of a mobile robot using only the features derived from the center camera. The second neural network model is used for estimating the orientation of a mobile robot using features derived from both the centre and side cameras. The third neural network model is used to estimate the orientation using features derived from the composition matrix. The fourth neural network model is used for estimating the orientation using Singular Value Decomposition (SVD) technique. Simulation results show that the proposed algorithm can be used to estimate the orientation of the mobile robot accurately.
