  • Systems and methods for 3-dimensional (3D) positioning of imaging device
    Patent number: 11233946
    Abstract: A method and a system for updating coordinate conversion parameters are provided. The method may include obtaining a first image captured by an imaging apparatus under a first configuration, selecting a feature point of an object in the first image and obtaining first coordinates of the feature point of the object in the first image. The method may further include causing the imaging apparatus to change from the first configuration to a second configuration. The method may further include obtaining a second image captured by the imaging apparatus under the second configuration, identifying the feature point of the object in the second image, and obtaining second coordinates of the feature point of the object in the second image. The method may further include updating the initial coordinate conversion parameters to generate an updated coordinate conversion parameter set.
