Embodiment Construction

[0023] Eye tracking is mainly to study the acquisition, modeling and simulation of eye movement information. One is to track according to the feature changes of the eyeball and its surroundings, the other is to track according to the change of iris angle, and the third is to actively project infrared light beams to the iris to extract features. .

[0024] figure 1 Schematic of adjusting the camera for feedback. Add a human eyeball image acquisition device on the head-mounted recording device, that is, a near-eye camera that is specially used to record people's eyeballs, and record the moving pictures of people's eyeballs when the recording device is recording.

[0025] According to the recorded picture, the center point of the eyeball of the person is located. The trajectory of the eyeball is obtained through computer processing, that is, the trajectory of the two eyeballs is modeled and simulated. According to the obtained trajectory map of the human eyeball, the head-mount...

Abstract

The invention provides a method for acquiring an optimal visual field through a head-mounted video recording device. The method comprises the steps that a human eyeball image acquisition device is additionally arranged on the head-mounted video recording device and used for specifically recording images of one eyeball of a person to capture the movement conditions of the eyeball of the person; the recorded images are subjected to eyeball marking, and a model is established through a computer to simulate the movement trajectories of two eyeballs; according to obtained trajectory charts of the eyeballs of the person, data are obtained, the data and the images recorded by the former video recording device are subjected to correlation treatment, then a group of data will be obtained, and the data will conduct circulation without a large change in many cases; the circulation data are extracted, and the circulation data and data recorded by a front camera are subjected to inverse correlation operation, so that the images are expanded or cut, and most effective storage of final images is achieved. Meanwhile, the head-mounted video recording device can be controlled to move according to the movement trajectories of the eyeballs of the person through software, so that recording within an optimal visual field is achieved.

Description

technical field [0001] The present invention relates to eyeball capturing technology and processing eyeball tracking technology, some corresponding control methods and wearable video recording equipment. Background technique [0002] In recent years, eye-tracking technology has developed rapidly and is used in computers and mobile phones. For example, Samsung and LG have launched several mobile phones using eye-tracking technology. You can control the up and down sliding of the screen by moving the eyeballs up and down, and control the left and right page turning of the screen by moving the eyeballs left and right. LG's mobile phone can recognize human eyes to control the playback and stop of the video player. When people look at the mobile phone with their eyes Interface, when the video player is in the playing state, when people's eyes leave the phone page, the video player will automatically stop. In addition, in computer games in recent years, some people have developed...
