  • Method and system for calibrating imaging system
    Patent number: 10930013
    Abstract: Provided are a method and system for calibrating parameters of an imaging system comprising at least one imaging device and broad and structured light sources, the method comprising: the at least one imaging device sequentially capturing broad light source image data and structured light source image data of one or more scenes using the broad and structured light sources, respectively; generating a photogrammetric model of the broad light source image data and a photogrammetric model of the structured light source image data using respective coordinates of the broad and structured light source image data; determining corresponding features in the respective photogrammetric models; iteratively solving parameters of the imaging system to correct variations between corresponding features in the respective photogrammetric models, converge the models and obtain calibration parameters; and applying the calibration parameters to the imaging system to compensate for errors in the relative positions of the imaging dev
