In general, the terminal device is relatively miniaturized and inexpensive, and at the same time, vision detection can be automatically performed in conjunction with a user-specific use scenario, thereby improving the frequency of vision detection of the user.
In order that those skilled in the art will better understand the present invention, reference will now be made to the accompanying drawings in which embodiments of the invention are illustrated, it being apparent that the embodiments described are only some, but not all, of the embodiments of the invention. Based on the embodiments of the present invention, it should be understood that the present invention is within the scope of protection.
It will be appreciated that the terminal devices involved in embodiments of the present invention may include general hand-held, on-screen electronic terminal devices such as cell phones, smart phones, portable terminals, personal digital assistants (Personal Digital Assistant, PDA), portable multimedia player (Personal Media Player, PMP) devices, notebook computers, notebook (Note Pad), wireless broadband (Wireless Broadband, wibro) terminals, tablet computers (Personal Computer, PC), smart PCs, point of sale (POS), and car computers, among others.
The terminal device may also comprise a wearable device. The wearable device may be worn directly on the user or may be a portable electronic device integrated into the user's clothing or accessories. The wearable device is not only a hardware device, but also can realize powerful intelligent functions through software support and data interaction and cloud interaction, such as: the mobile phone terminal has the advantages of calculating function, positioning function and alarming function, and can be connected with mobile phones and various terminals. Wearable devices may include, but are not limited to, wrist-supported watch types (e.g., watches, wrist products, etc.), foot-supported shoes (e.g., shoes, socks, or other leg wear products), head-supported Glass types (e.g., glasses, helmets, headbands, etc.), and smart apparel, school bags, crutches, accessories, etc. in various non-mainstream product forms.
In the following, by way of example, the technical solution of the present invention is further described, as shown in fig. 1, which is a schematic diagram of an embodiment of a method for detecting eyesight in an embodiment of the present invention, and may include:
101. in case it is determined that the terminal device is in a specific use scenario, a first image is acquired by the vision sensor using an infrared eccentric photography technique, the first image comprising a first pupil image of the user.
In the example of the present invention, in the case that the terminal device determines that the terminal device is in a specific usage scene, the terminal device acquires a first image by using an infrared eccentric photography technology through the vision sensor, where the first image includes a first pupil image of a user, and may include: under the condition that the terminal equipment is in a specific use scene, the terminal equipment obtains the current distance from the pupil of the user to the vision sensor through a distance measuring sensor; and under the condition that the current distance is greater than or equal to a preset distance threshold value, the terminal equipment acquires a first image through the vision sensor by using an infrared eccentric photographing technology. I.e. if the current distance from the pupil of the user to the vision sensor is greater than or equal to a preset distance threshold, the terminal device may acquire the first image by using the infrared eccentric photography technique through the vision sensor. And if the current distance between the pupil of the user and the vision sensor is smaller than a preset distance threshold value, not performing operation.
The preset distance threshold of the terminal equipment is 35 cm, if the current distance from the pupil of the user to the vision sensor is 37 cm through the distance measuring sensor, and the current distance is 37 cm and is larger than the preset distance threshold by 35 cm, the terminal equipment acquires a first image through the vision sensor by using an infrared eccentric photography technology; if the terminal equipment obtains that the current distance from the pupil of the user to the vision sensor is 28 cm through the distance measuring sensor, and the current distance is 28 cm less than the preset distance threshold value of 35 cm, the terminal equipment cannot obtain the first image through the vision sensor by using the infrared eccentric photography technology.
Optionally, the terminal device may first determine whether the terminal device meets a preset condition when determining that the terminal device is in a specific usage scenario. The terminal device may perform vision testing if the terminal device satisfies at least one of the preset conditions. Wherein, the preset conditions include: the residual memory of the terminal equipment is larger than a preset memory threshold value; the current temperature of the terminal equipment is smaller than a preset temperature threshold value; and the residual electric quantity of the terminal equipment is larger than a preset electric quantity threshold value. Illustratively, the preset power threshold of the terminal device is 70%, and when the remaining power is greater than or equal to 70% of the preset power threshold, the terminal device may perform vision inspection.
Optionally, the terminal device may determine whether the user is within the measurement range of the ranging sensor when determining that the terminal device is in a specific usage scenario, and if the current distance from the pupil of the user to the vision sensor is within the measurement range, the terminal device enters a measurement mode and adjusts the angle of the ranging sensor to a suitable position, and obtains the current distance from the pupil of the user to the vision sensor through the ranging sensor. If the current distance from the pupil of the user to the vision sensor is not in the measuring range, no operation is performed. Alternatively, if an angular deviation is generated when the ranging sensor measures the current distance, the terminal device may automatically fix the angular deviation.
Optionally, the terminal device determines that it is in a specific usage scenario may include: the terminal equipment detects the continuous time length of the user gazing at the screen of the terminal equipment; and under the condition that the continuous time length is greater than or equal to a preset time length threshold value, the terminal equipment determines that the terminal equipment is in a specific use scene. By way of example, the threshold duration threshold in the terminal device is 40 minutes, and when the continuous duration of the user looking at the terminal device is 42 minutes, the terminal device can determine that it is in a particular use scenario, wherein 42 minutes is greater than 40 minutes. Or alternatively, the process may be performed,
In the case of detecting that the user gazes at a specific content or a specific light source on the screen of the terminal device, the terminal device determines that the terminal device is in a specific use scene, and fig. 2 is a schematic diagram of the user gazing at the specific content or the specific light source on the screen of the terminal device; wherein the specific content may include a preset picture or a preset animation, and the specific light source includes a preset additional visible light source.
It will be appreciated that the specific content or specific light source on the screen of the terminal device may be real-time or periodic, and is not limited in this regard. Taking the example that the appearance period of the specific content on the screen of the terminal equipment is one month, assuming that the preset specific content of the terminal equipment is a preset picture, setting the preset picture to appear at 21 points in the fifth night of each month, and determining that the terminal equipment is in a specific use scene by only watching the preset animation. Optionally, if the screen of the terminal device is in a screen-off state, when the preset time is reached, the terminal device informs the user that the detection vision is achieved by means of message prompt tones or voice broadcasting.
It is understood that the terminal device includes a vision sensor and a ranging sensor. Fig. 3 is a schematic diagram of a view sensor included in a terminal device according to an embodiment of the present invention, which may include, but is not limited to: the device comprises a scanning lamp, an infrared camera, an infrared light shielding plate, an infrared narrow-band filter and a processor, wherein the scanning lamp consists of a strip-shaped infrared light emitting diode. The scanning lamp is positioned in front of the infrared camera. The connection mode of the vision sensor and the distance measuring sensor may be serial connection or parallel connection, and is not limited herein.

And under the condition that the pupil position in the first pupil image is matched with a preset pupil position, a scanning lamp is started through the vision sensor, and a second image is acquired by using the infrared eccentric photographing technology, wherein the second image comprises a second pupil image of the user.

Due to structural problems, a scanning light bar can only measure a small diopter range, not the full range.
103. And analyzing and obtaining the first diopter according to the second pupil image.
Optionally, the analyzing, by the terminal device, the first diopter according to the second pupil image may include: obtaining an effective light bar range according to the second pupil image; and analyzing and obtaining the first diopter according to the effective light bar range.

Alternatively, if the vision test is the first time, no comparison is made, and only the health prompt corresponding to the test result is required to be displayed.
In an embodiment of the present invention, a method of detecting vision is provided. The terminal equipment judges whether the current distance from the pupil of the user to the vision sensor is greater than or equal to a preset distance threshold value through photographing for the first time, if so, the terminal equipment starts a scanning lamp, the vision sensor acquires a second image through an infrared eccentric photographing technology, and the vision of the user is detected through analyzing the effective light bar range in the second pupil image. In this way, the infrared eccentric photography technique can be applied to the terminal device. The terminal device is generally miniaturized and has low cost, and meanwhile, the vision detection can be automatically carried out by combining a specific use scene of a user, so that the frequency of vision detection of the user is improved.
