Abstract

The invention provides a method for calculating the ocular distance, comprising the following steps: using a three-dimensional image display device to generate one or multiple second display points and displaying one or multiple virtual reference points; obtaining one or multiple calibration points, wherein the calibration points are generated by that a user uses an interaction component to interact with the reference points; and calculating the ocular distance of the user in accordance with the opposite positions among the display points, the calibration points and the user. In the method, the user operates the interaction component to interact with the one or multiple virtual reference points, thus calculating the ocular distance of the user, thereby correctly estimating the actual feeling of the user for three-dimensional image positions and depths of field.

Description

technical field [0001] The invention relates to a method for calculating the distance between eyes, in particular to a method for calculating the distance between eyes which can be applied in a three-dimensional image interactive system. Background technique [0002] In recent years, the application of 3D images in the entertainment industry has continued to innovate, and various 3D image technologies have gradually entered the lives of ordinary people. [0003] The imaging principle of the 3D image is to use the left eye and the right eye to capture two different images respectively, and the brain synthesizes the two different images into a 3D image with front and rear depth of field. [0004] Generally speaking, 3D imaging technologies can be divided into glasses-based technology and naked-eye technology. Glasses-based technology requires the user to wear special glasses, and the left and right eyes can see different images by using different polarization angles of light ...
