Embodiment Construction
[0024] like figure 1 Shown, a kind of three-dimensional modeling method of eyeball, this method comprises:
[0025] Step 1: Obtain multiple groups of fundus images of the eyeball through a single camera, and the images respectively describe the state of each angle of eyeball rotation. like figure 2 As shown, using eyeball rotation to generate continuous fundus two-dimensional image data, an image sequence is generated, such as image 3 shown.
[0026] Step 2, camera calibration is to establish an imaging model, determine the position and attribute parameters of the camera, and determine the correspondence between the object point and its image point in the space coordinate system. The calibration method of the camera is to fit through the least squares method to determine the transformation matrix of the three-dimensional space point mapping to the two-dimensional image point. An effective camera model, in addition to accurately recovering the three-dimensional informatio...
