Embodiment 1
[0039] A line-of-sight recognition method provided in Embodiment 1 of the present application is described below, please refer to the attached figure 1 , the method includes:
[0040] Step S101, acquiring a first image, the first image includes a preset reference object, and the preset reference object is an item carried by a vision detection user.
[0041] In step S101 , the first image refers to an image of the vision testing user before preparing for the vision testing or an image of the vision testing user performing the vision testing. It should be understood that the first image may be an image collected by the camera when the terminal device performs a vision detection operation, or an image collected by other terminal devices when performing a vision detection operation and then sent to the terminal device. The user can select the source of the first image according to actual needs, which is not specifically limited in this application.
[0042] The preset reference ...
Embodiment 2
[0114] Figure 8 An example of a line of sight recognition device is shown, and for ease of description, only parts related to the embodiment of the present application are shown. The device 800 includes:
[0115] The first image acquisition module 801 is configured to acquire a first image, the first image includes a preset reference object, and the preset reference object is an item carried by a vision detection user.
[0116] The recognition module 802 is to recognize the shape of the preset reference object in the first image to obtain the first shape.
[0117] The judging module 803 is configured to determine that the vision detection user's line of sight is not perpendicular to the visual mark if the first shape is different from the second shape, and the second shape is the preset reference when the vision detection user's line of sight is perpendicular to the visual mark shape of the object.
[0118] Optionally, the determination module 803 is configured to execute:...
