Pickup of objects in three-dimensional display

A method, comprising:

• acquiring, by a device comprising a processor, a first location information, with respect to a user, about a gaze point of an eye of the user;
• and
• determining an object, determined to have been picked up by the user, according to a second location information about the user, motion posture information about the user, the first location information and distribution information about a plurality of objects in a display space;
• wherein acquiring the first location information, with respect to the user, about the gaze point of the eye of the user comprises:
• collecting at least one image of a fundus of the eye;
• adjusting at least one imaging parameter of an optical path between at least one location of the at least one image and the eye until at least a subset of the at least one image that satisfies at least one defined clarity criterion is collected;
• and
• processing the at least one image, and obtaining the first location information according to the at least one imaging parameter corresponding to the at least the subset of the at least one image that satisfies the at least one defined clarity criterion and at least one optical parameter of the eye.

A non-transitory computer-readable tangible media having at least one executable instruction stored thereon that when executed by a processor, causes the processor to perform operations, comprising:

• acquiring a first location information, with respect to a user, about a gaze point of an eye of the user;
• and
• determining an object picked up by the user according to a second location information about the user, motion posture information about the user, the first location information and distribution information about a plurality of objects in a display space;
• wherein acquiring the first location information, with respect to the user, about the gaze point of the eye of the user comprises:
• collecting at least one image of a fundus of the eye;
• adjusting at least one imaging parameter of an optical path between at least one location of the at least one image and the eye until at least a subset of the at least one image that satisfies at least one defined clarity criterion is collected;
• and
• processing the at least one image, and obtaining the first location information according to the at least one imaging parameter corresponding to the at least the subset of the at least one image that satisfies the at least one defined clarity criterion and at least one optical parameter of the eye.

A pickup device, comprising a processing device and a memory, wherein the memory stores a computer-executable instruction, the processing device is connected with the memory via a communication bus, and when the pickup device operates, the processing device executes the computer-executable instruction stored in the memory, the pickup device executes operations, comprising:

• acquiring a first location information, with respect to a user, about a gaze point of an eye of the user;
• and
• determining an object picked up by the user according to a second location information about the user, motion posture information about the user, the first location information and distribution information about a plurality of objects in a display space;
• wherein acquiring the first location information, with respect to the user, about the gaze point of the eye of the user comprises:
• collecting at least one image of a fundus of the eye;
• adjusting at least one imaging parameter of an optical path between at least one location of the at least one image and the eye until at least a subset of the at least one image that satisfies at least one defined clarity criterion is collected;
• and
• processing the at least one image, and obtaining the first location information according to the at least one imaging parameter corresponding to the at least the subset of the at least one image that satisfies the at least one defined clarity criterion and at least one optical parameter of the eye.
