Embodiment 1

[0026] Such as figure 1 Shown is a flowchart of a method for detecting the wearing state of glasses provided by an embodiment of the present invention, and the method includes the following steps:

[0027] In step S101 , the wearing state of the standard glasses is obtained, and the wearing state includes: distance information between the glasses and the face plane, and spatial angle information between the glasses and the face plane.

[0028] In the embodiment of the present invention, the device for detecting the wearing state of the glasses first acquires the wearing state of the standard glasses, which includes but not limited to: the distance information between the glasses and the face plane, and the spatial angle information between the glasses and the face plane. The step of obtaining the wearing state of the standard glasses is specifically:

[0029] 1. When the user wears the glasses, the distance information between the glasses and the face plane and the spatial an...

Embodiment 2

[0053] Such as figure 2 Shown is a structural diagram of the device for detecting the wearing state of glasses provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0054] The standard glasses wearing state obtaining unit 201 is configured to obtain the standard glasses wearing state, the wearing state includes: the distance information between the glasses and the face plane, and the spatial angle information between the glasses and the face plane.

[0055] In the embodiment of the present invention, the device for detecting the wearing state of the glasses first acquires the wearing state of the standard glasses, which includes but not limited to: the distance information between the glasses and the face plane, and the spatial angle information between the glasses and the face plane. The standard glasses wearing state acquisition unit 201 includes:

Abstract

The present invention is applied to the data processing field, and provides a method and apparatus for detecting a glasses wearing state. The method comprises the steps of: obtaining a standard glasses wearing state; acquiring a first glasses wearing state according to a first preset acquisition frequency when a user wears glasses ; performing a first comparison between the first glasses wearing state and the standard glasses wearing state, and comparing whether the first glasses wearing state exceeds a value range of the standard glasses wearing state or not; acquiring a second glasses wearing state according to a preset second acquisition frequency if the result of the first comparison is exceeding, the second acquisition frequency being higher than the first acquisition frequency; performing a second comparison between the second glasses wearing state and the standard glasses wearing state, and comparing whether the second glasses wearing state exceeds a value range of the standard glasses wearing state or not; and feeding back the glasses wearing state to the user according to the result of the second comparison.

Description

technical field [0001] The invention belongs to the field of data processing, and in particular relates to a method and a device for detecting the wearing state of glasses. Background technique [0002] In the daily dispensing for the purpose of correcting refractive errors, professional opticians will scientifically configure appropriate lenses and frames for the optician according to: lens diopter, anteversion angle, vertex distance and vertex diopter, and optical center. However, during the daily wear of glasses by the spectacle wearer, except for the first lens diopter, the other 3 points (forward tilt angle, vertex distance, and optical center) will all change due to changes in the wearer's wearing state, thereby affecting It affects the corrected vision of the spectacle wearer, and even leads to a further deepening of the refractive error. [0003] In the prior art, when measuring the wearing state of personal glasses, an image sensor is used to obtain an image of the...
