Embodiment Construction

[0070] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0071] Eye tracking technology is based on the image processing method. The camera device (such as CCD camera) installed in front of the eye captures the image of the eye in real time, and obtains the center coordinates of the pupil through image processing. At the same time, the high-brightness spot (purkinje image ) as a reference point. When the eyeball gazes at different positions, the approximately spherical eyeball rotates and the light spot does not move. Using the relationship between the pupi...

Abstract

The embodiment of the invention provides a pupil positioning device and method, and a display driver of a virtual reality device. The pupil positioning device comprises a preprocessing circuit and a coordinate processing circuit, wherein the preprocessing circuit is used for preprocessing an eye image during an eye image transmission process, obtaining all boundary points of the eye image, and thecoordinate processing circuit is used for performing communication area processing on all boundary points, and determining the pupil center coordinates according to the maximum communication area. Aneye image is preprocessed in the data transmission process, the pupil center coordinates are determined by adopting a hardware communication region processing mode, and the large-data-quantity operation caused by delay is avoided. The processing speed is increased, the processing time is shortened, and the storage resources and the logic resources are saved. Hardware implementation is convenient,and the pupil positioning device is integrated in a display driver of a head-mounted virtual reality device.

Description

technical field [0001] The invention relates to the technical field of eye control, in particular to a pupil positioning device and method, and a display driver of a virtual reality device. Background technique [0002] In recent years, virtual reality (Virtual Reality, VR) / augmented reality (Augmented Reality, AR) technologies have been gradually applied to fields such as display, games, and medical treatment. With the development of technology, people's expectations for VR / AR are getting higher and higher. The interaction method of changing the viewing angle by turning the head can no longer bring people a satisfactory product experience. Therefore, many manufacturers are using eye tracking technology Accelerate the deployment to the VR / AR field. [0003] Eye Tracking technology is an intelligent human-computer interaction technology that uses eye movements to control machines. All operations can be completed by "seeing" with eyes. It not only frees hands, but also is the...
