title = "Linear pose estimation algorithm based on quaternion",
abstract = "A novel linear camera pose estimation algorithm is presented using known 3D to 2D line correspondences and point correspondences. The rotation parameters are represented by unit quaternion. For n (n>=4) correspondences, we establish an equation system with 2n quadratic equations in thirteen variables and apply the {"}relinearization{"} method to obtain the rotation parameters and translation parameters simultaneously. We compare our algorithm with Ansar's NLL algorithm for line correspondences by some synthetic experiments. Our algorithm performs better on the aspect of running time and accuracy of determined pose parameters. Some real experiments are produced by 1 point-3 lines, 2 points-2 lines, 3 points- 1 line correspondences. The projection of a 3D model is applied to estimate the performance of our algorithm.",
