单目视觉下目标物高度测量的研究

his paper presents a simple calibration approach to height estimation based on single view metrology.Instead of calibrating intrinsic parameters,our approach aims to estimate the vanishing points of a stationary camera.The calibration process is formulated as finding the calibrated parts,then obtaining the feature points through the calibrated parts processing,and then defining a novel objective function to deal with an optimization problem,in which twelve parameters for estimating vanishing points are defined.The genetic algorithm with Cauchy mutation operator is further used for obtaining robust results.The major advantages of the proposed approach are: 1).it is easy to setup since only a cubic box and some optional line segments are reauired; and 2).it works without camera's intrinsic parameters; then 3).the process is automated without manual work.
