[0032] The application environment of the smart glasses code scanning method shown in the embodiment of the present application includes smart glasses; the smart glasses include a glasses body, a light sensor, a camera device, a fill light and a processor. Among them, the light sensor, the camera device, the fill light and the processor are all arranged on the glasses body; the light sensor, the camera device and the fill light are all connected to the processor, and the light sensor, the camera device and the fill light are used to receive and execute the control instructions of the processor, and the light sensor transmits the detected ambient light intensity to the processor, and the camera device transmits the captured camera image to the processor. In addition, in some embodiments, the smart glasses may also include one or more other sensors, such as one or more of a depth camera, an infrared sensor, an ultrasonic sensor, a Hall sensor, and the like. Among them, the specific setting position of each sensor can be determined according to the actual application scenario, and this application does not limit it.

[0033] The main body of the glasses includes a frame and two temples connected to the frame. A lens is provided on the side of the frame close to the wearer's eyes. The user can observe the real environment through the lens, or watch the virtual reality image displayed on the lens. The light sensor is used to detect the light intensity of the real environment under the wearer's field of view. The camera device is used to capture the image of the real environment under the wearer's field of view. The fill light is used to enhance the light intensity of the real environment.

In addition, the application environment of the smart glasses code scanning method may also include a processing device independent of the smart glasses. After the processing device is connected to the light sensor, the camera device, and the fill light, the smart glasses code scanning method of the present application may be implemented in a pure software manner, or in a combination of software and hardware.

[0035] To this end, the embodiments of the present application propose a smart glasses code scanning method, device, storage medium and electronic device.

[0036] The following will be combined with the attached Figures 1 to 5 , the smart glasses scanning method provided in the embodiment of the present application is introduced in detail.

[0037] See also Figure 1 The smart glasses code scanning method provided in the embodiment of the present application includes the following steps:

[0038] Step S101: Obtain the code scanning environment parameters of the smart glasses; obtain the first code scanning parameters according to the code scanning environment parameters; the first code scanning parameters include camera screen parameters.

[0039] It can be understood that the smart glasses scanning method of the embodiment of the present application is applied to the scanning of graphic codes, wherein the graphic code can be a QR code or a barcode, etc., which can be a black and white graphic that records data symbol information distributed in a plane according to a certain rule using certain specific geometric shapes.

[0040] The code scanning environment parameters include the ambient light intensity. In the embodiment of the present application, when the wearer wears the smart glasses, or when it is detected that the wearer needs to perform a graphic code scanning operation, the processor sends a start instruction to the light sensor, and the light sensor detects the ambient light intensity of the real environment under the wearer's field of view. Among them, the detection of whether the wearer needs to perform a graphic code scanning operation can be that the wearer triggers the code scanning control on the lens, thereby causing the processor to detect the graphic code scanning operation, or it can be that the wearer's eye movement is detected as a preset action, thereby causing the processor to detect the graphic code scanning operation.

[0041] The camera picture parameters are used to indicate the quality of the captured picture, and the camera picture parameters include one or more of the following: exposure timing of the camera device, exposure time of the camera device, white balance of the camera device, clarity of the camera device, contrast of the camera device and brightness of the camera device.

[0042] In an optional embodiment, the processor presets a mapping relationship between the code scanning environment parameter and the first code scanning parameter, and matches the first code scanning parameter corresponding to the code scanning environment parameter through the mapping relationship.

[0043] In another optional embodiment, the processor presets a calculation formula between the code scanning environment parameter and the first code scanning parameter, and uses the calculation formula to calculate according to the code scanning environment parameter to obtain the corresponding first code scanning parameter.

[0044] In another optional embodiment, the processor is preset with a trained environment scanning parameter model, and the scanning environment parameters are input into the environment scanning parameter model to obtain the corresponding first scanning parameters. The environment scanning parameter model can be obtained by existing neural network training.

[0045] Step S102: Determine the scanning distance and the size of the graphic code; obtain the second scanning parameter according to the scanning distance and the size of the graphic code; the second scanning parameter includes the camera resolution and the camera focal length.

[0046] The scanning distance can be obtained through input by the wearer, or through detection by a distance sensor set on the main body of the glasses, or by pre-shooting the image to be detected through preset camera resolution and camera focal length and then estimating the distance.

[0047] The size of the graphic code can be obtained through input by the wearer, or it can be estimated by pre-shooting the image to be detected through preset camera resolution and camera focal length.

[0048] Camera resolution refers to the degree of resolution of the camera device to the photographed scene, generally referring to the number of pixels that can be provided in one frame.

[0049] The focal length of a camera is the distance from the optical center of the camera lens to the focal point of light when parallel light is incident. The length of the focal length determines the image size and field of view of the camera. The shorter the focal length, the wider the field of view of the camera lens, and the smaller the focal length, the narrower the field of view of the camera lens.

[0050] In an optional embodiment, the processor presets a mapping relationship between the scanning distance and the graphic code size and the second scanning parameter, and matches the second scanning parameter corresponding to the scanning distance and the graphic code size through the mapping relationship.

[0051] In another optional embodiment, the processor presets a calculation formula between the scanning distance and the graphic code size and the second scanning parameter. Through the calculation formula, the corresponding second scanning parameter is obtained according to the scanning distance and the graphic code size.

[0052] In another optional embodiment, the processor is preset with a trained distance scanning parameter model, and the scanning distance and the size of the graphic code are input into the distance scanning parameter model to obtain the corresponding second scanning parameter.

[0053] By adaptively obtaining the second scanning parameter according to the scanning distance and the size of the graphic code, the second scanning parameter can be adaptively adjusted at different distances, especially in long-distance scanning scenarios, to obtain a clear image.

[0054] Step S103: according to the first code scanning parameter and the second code scanning parameter, the smart glasses are set and a corresponding graphic code image is obtained.

[0055] After obtaining the first code scanning parameter and the second code scanning parameter, the photographing parameters of the camera device of the smart glasses are adjusted, and the corresponding first code scanning parameters such as the exposure timing of the camera device, the exposure time of the camera device, the white balance of the camera device, the clarity of the camera device, the contrast of the camera device and the brightness of the camera device are set, and the corresponding second code scanning parameters such as the camera resolution and the camera focal length are set, so as to shoot the graphic code and obtain the corresponding graphic code image.

[0056] Step S104: Identify the graphic code image and obtain the scan result.

[0057] The method of identifying the graphic code image can be various existing methods that can be implemented, and this application will not go into details.

[0058] The embodiment of the present application obtains the scanning environment parameters of the smart glasses; obtains the first scanning parameters according to the scanning environment parameters; the first scanning parameters include the camera screen parameters; determines the scanning distance and the graphic code size; obtains the second scanning parameters according to the scanning distance and the graphic code size; the second scanning parameters include the camera resolution and the camera focal length; sets the smart glasses according to the first scanning parameters and the second scanning parameters, and obtains the corresponding graphic code image; recognizes the graphic code image, and obtains the scanning result. The embodiment of the present application adaptively obtains the first scanning parameters and the second scanning parameters through the scanning environment parameters, the scanning distance, and the graphic code size, so that clear graphic code images can be obtained for graphic codes of different environments, different distances, and different sizes, especially in long-distance scanning scenarios, thereby improving the scanning recognition efficiency and success rate, and improving the working efficiency of the smart glasses.

[0059] See also Figure 2In an optional embodiment, the code scanning environment parameter includes the ambient light intensity; the step of obtaining the first code scanning parameter according to the code scanning environment parameter in step S101 includes:

[0060] Step S1111: Compare the ambient light intensity with a preset ambient light intensity threshold.

[0061] The preset ambient light intensity threshold can be set according to actual needs. Generally speaking, the ambient light intensity threshold is the minimum threshold at which the camera device can capture a clear image;

[0062] Step S1112: If the ambient light intensity is greater than or equal to the ambient light intensity threshold, obtain a first code scanning parameter according to the ambient light intensity.

[0063] Step S1113: If the ambient light intensity is less than the ambient light intensity threshold, control the fill light to be turned on to fill the ambient light, and obtain the ambient light intensity after the fill light is obtained; according to the ambient light intensity after the fill light is obtained, obtain the first code scanning parameter.

[0064] If the ambient light intensity is greater than or equal to the ambient light intensity threshold, it means that by adjusting the first scanning parameter, the camera device can capture a clear image; if the ambient light intensity is less than the ambient light intensity threshold, it means that the light is too dark and a clear image cannot be captured by adjusting the first scanning parameter. Therefore, the processor controls the turn-on of the supplementary light to increase the ambient light intensity of the smart glasses, and then re-detects the ambient light brightness to obtain the first scanning parameter, thereby improving the scanning success rate and scanning clarity.

[0065] In an optional embodiment, the step of obtaining the first code scanning parameter according to the code scanning environment parameter in step S101 includes:

[0066] Step S1121: Match the code scanning environment parameter with a preset environment code scanning parameter library to obtain a first code scanning parameter; the environment code scanning parameter library stores a mapping relationship between each code scanning environment parameter and the first code scanning parameter.

[0067] The environmental scanning parameter library can store a one-to-one mapping relationship between each scanning environment parameter and the first scanning parameter; for example, when the scanning environment parameter is the ambient light brightness, each ambient light brightness corresponds to a first scanning parameter. The environmental scanning parameter library can also store a mapping relationship between each scanning environment parameter range and a first scanning parameter; for example, when the scanning environment parameter is the ambient light brightness, multiple ambient light brightness ranges will be set, and each ambient light brightness range corresponds to a first scanning environment parameter.

[0068] The embodiment of the present application can quickly and conveniently obtain the first scanning parameters by matching the scanning environment parameters with a preset environment scanning parameter library.

[0069] See also Figure 3 In an optional embodiment, the step of determining the scanning distance and the size of the graphic code in step S102 includes:

[0070] Step S1211: receiving the scanning distance and graphic code size input by the user.

[0071] The lenses of the smart glasses also serve as a display screen, which can display a scanning distance input control and a graphic code size input control. Users can enter the scanning distance and graphic code size on the scanning distance input control and the graphic code size input control.

[0072] Specifically, when using smart glasses to scan codes, the smart glasses provide two modes, automatic mode and manual mode, for users to scan codes. If the user selects the manual mode, the smart glasses will display a code scanning distance input control and a graphic code size input control to receive the code scanning distance and graphic code size input by the user. If the user selects the automatic mode, the smart glasses will automatically determine the code scanning distance and graphic code size, which will be specifically described in steps S1221-S1223.

[0073] Step S1212: Update the second scanning parameter according to the scanning distance and graphic code size input by the user.

[0074] It can be understood that the processor has a preset mapping relationship between the scanning distance and the graphic code size and the second scanning parameter, or has a preset calculation formula between the scanning distance and the graphic code size and the second scanning parameter, or has a preset trained distance scanning parameter model, so as to obtain the second scanning parameter corresponding to the scanning distance and the graphic code size input by the user according to the mapping relationship, the calculation formula or the trained distance scanning parameter model.

[0075] Step S1213: According to the first code scanning parameter and the updated second code scanning parameter, the graphic code image is collected for recognition.

[0076] The processor adjusts the graphic code image and the shooting parameters of the camera device of the smart glasses according to the second scanning parameters determined by the scanning distance and the graphic code size input by the user and the first scanning parameters, and sets the corresponding first scanning parameters such as the exposure timing of the camera device, the exposure time of the camera device, the white balance of the camera device, the clarity of the camera device, the contrast of the camera device and the brightness of the camera device, and sets the corresponding second scanning parameters such as the camera resolution and the camera focal length, so as to shoot the graphic code and obtain the corresponding graphic code image.

[0077] Step S1214: If the recognition fails, determine the scanning distance and the size of the graphic code based on the camera image.

[0078] It is understandable that if the recognition is successful, the recognition result is directly obtained. If the recognition fails, it means that the scanning distance and the graphic code size are not appropriate. In this case, the scanning distance and the graphic code size are re-determined based on the camera image.

[0079] The embodiment of the present application determines the second scanning parameter based on the scanning distance and graphic code size input by the user, and when recognition fails, the scanning distance and graphic code size are adaptively re-determined, and the second scanning parameter is re-determined, so as to improve the recognition success rate and the recognition efficiency.

[0080] See also Figure 4 In an optional embodiment, the step of determining the scanning distance and the size of the graphic code in step S102 includes:

[0081] Step S1221: using the first code scanning parameter and the preset second code scanning parameter to detect whether there is a graphic code in the camera image.

[0082] Specifically, when using smart glasses to scan codes, the smart glasses provide automatic mode and manual mode. If the user selects the automatic mode, the processor will use the first scanning parameter and the pre-set second scanning parameter to detect whether there is a graphic code in the camera image.

[0083] Step S1222: If a graphic code exists, capture a camera image for recognition.

[0084] Step S1223: If the recognition fails, determine the scanning distance and the size of the graphic code based on the camera image.

[0085] It can be understood that if the recognition is successful, it means that the preset second scanning parameters are appropriate and the recognition result can be obtained directly. If the recognition fails, it means that the preset second scanning parameters are not appropriate and it is necessary to re-determine the scanning distance and graphic code size based on the camera image to determine the appropriate second scanning image.

[0086] The embodiment of the present application adopts the first scanning parameter and the preset second scanning parameter to scan the code. When the recognition is unsuccessful, the scanning distance and the size of the graphic code are adaptively determined, and then the second scanning parameter is determined, which can improve the scanning success rate and scanning efficiency.

[0087] See also Figure 5 In an optional embodiment, the steps of determining the scanning distance and the size of the graphic code according to the camera image in step S1213 and step S1223 include:

[0088] Step S1231: Determine the size of the graphic code according to the camera image.

[0089] It is understandable that, in step S1213, the size of the graphic code captured at the camera resolution corresponding to the updated second code scanning parameter can be obtained based on the camera image. In step S1223, the size of the graphic code at the camera resolution corresponding to the preset second code scanning parameter can be obtained based on the camera image.

[0090] Step S1232: Match the graphic code size with a preset distance model library to obtain a code scanning distance; wherein the distance model library stores a mapping relationship between each graphic code size and a code scanning distance.

[0091] The distance model library may store a one-to-one mapping relationship between each graphic code size and a code scanning distance. The distance model library may also store a mapping relationship between each graphic code size range and a code scanning distance.

[0092] The embodiment of the present application can quickly and conveniently obtain the scanning distance by matching the graphic code size with a preset distance model library.

[0093] In an optional embodiment, obtaining the second code scanning parameter according to the code scanning distance and the size of the graphic code in step S102 includes:

[0094] Step S1231: Match the code scanning distance and the graphic code size with a preset distance code scanning parameter library to obtain a second code scanning parameter; the distance code scanning parameter library stores a mapping relationship between each code scanning distance and graphic code size and the second code scanning parameter.

[0095] The distance code scanning parameter library may store a one-to-one mapping relationship between each code scanning distance and graphic code size and the second code scanning parameter. The distance code scanning parameter library may also store a mapping relationship between each code scanning distance and graphic code size range and a second code scanning parameter.

[0096] The embodiment of the present application can quickly and conveniently obtain the second scanning parameter by matching the scanning distance and the graphic code size with a preset distance scanning parameter library.
