It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device.

[0028] It should be noted that the one or more processors and / or other data processing circuits described above may generally be referred to herein as "data processing circuits".

[0030] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 .

[0031] Figure 2 FIG. 1 is a flow chart of a method for calibrating illumination according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0032] Step S202 : collecting a first illuminance of a preset light source on a standard surface and a second illuminance of a preset light source on a target surface.

[0033] In this step, a preset light source may be used to illuminate the standard surface and the target surface to obtain a first illuminance and a second illuminance. The standard surface may be used as a reference surface, that is, the illuminance on the surface is taken as an accurate value. For example, a white smooth surface may be used as a standard surface. The preset light source may be used to illuminate the white smooth surface to obtain a first illuminance, and then the preset light source may be used to illuminate the target surface to obtain a second illuminance.

[0034] Step S204: determining a compensation method corresponding to the target surface according to the first illumination and the second illumination.

[0035] In this step, in order to normalize the illumination, the second illumination is compensated in a certain manner so that the illumination on the target surface measured should be the same as the illumination on the standard surface. Therefore, the compensation method corresponding to the target surface can be determined according to the first illumination and the second illumination.

[0036] Step S206, obtaining the original illuminance of the target light source to be detected on the target surface.

[0037] Step S208: determining the target illuminance corresponding to the target light source based on the original illuminance and the compensation method.

[0038] The original illuminance obtained is the illuminance that has not been compensated by the compensation method. According to the previously determined compensation method and the original illuminance, the target illuminance corresponding to the target light source can be obtained. What the user sees is the target illuminance after compensation.

[0039] Through the above steps, the purpose of normalizing the illuminance is achieved, thereby realizing the technical effect of improving the accuracy of the acquired illuminance, and further solving the technical problem that the material and color of the light reflecting surface will affect the collected illuminance data, resulting in the acquired illuminance data being inaccurate.

[0040] As an optional embodiment, the preset light source is used to emit light with various brightness.

[0041] Optionally, the preset light source can emit light of various brightnesses, which can be used for subsequent calibration of the illumination. Because when the compensation method is determined later, when the illumination is calibrated using the compensation formula, it is necessary to first obtain the illumination of the light irradiated on the surface at different brightnesses, and then substitute it into the formula to obtain the unknown number in the formula. Therefore, the preset light source emitting light of various brightnesses provides convenient conditions for the subsequent determination of the compensation method.

[0042] As an optional embodiment, when the compensation method is to use a target compensation formula for compensation, a first illuminance of a preset light source on a standard surface and a second illuminance of a preset light source on a target surface are collected, including: obtaining a target number of compensation coefficients in an initial compensation formula, wherein the compensation coefficients in the initial compensation formula are unknown numbers; collecting multiple groups of illuminance data under a target number of rays of light emitted by the preset light source, wherein the number of groups of the multiple groups of illuminance data matches the target number, and any group of illuminance data in the multiple groups of illuminance data includes the illuminance corresponding to the standard surface and the illuminance corresponding to the target surface.

[0043] As an optional embodiment, when the compensation method is to use a target compensation formula for compensation, the compensation method corresponding to the target surface is determined according to the first illuminance and the second illuminance, including: solving the unknown number corresponding to the compensation coefficient in the initial compensation formula based on multiple sets of illuminance data, and obtaining the target compensation formula including the compensation coefficient as a known number.

[0044] Optionally, the preset light source can emit light of multiple brightnesses for subsequent calibration of the illumination. When the compensation method is to use a target compensation formula for compensation, the initial compensation formula can be obtained first to determine the target number of compensation coefficients therein. The illumination can be collected according to the target number. For example, if there are two compensation coefficients, two sets of illumination data can be obtained, wherein the brightness of the light emitted by the preset light source corresponding to each set of illumination data is different, so that the corresponding illumination irradiated to the surface will also be different, which is convenient for solving the unknowns in the formula. Each set of illumination data will include an illumination on a standard surface and an illumination on a target surface. Substituting each set of illumination data into the formula, multiple equations with unknown compensation coefficients can be obtained, and the compensation coefficients can be obtained by solving the set of simultaneous equations. Based on the obtained compensation coefficients, the target compensation formula can be obtained, and the target compensation formula can be used to calibrate the illumination.

[0045] As an optional embodiment, when the compensation method is to use a linear compensation formula for compensation, the linear compensation formula characterizes that the illuminance on the standard surface changes linearly with the illuminance on the target surface, and the compensation method corresponding to the target surface is determined according to the first illuminance and the second illuminance, including: determining the compensation method corresponding to the target surface according to the first group of illuminances and the second group of illuminances, wherein the first group of illuminances includes the first illuminance on the standard surface and the second illuminance on the target surface when a preset light source is turned on, and the second group of illuminances includes the first illuminance on the standard surface and the second illuminance on the target surface when the preset light source is turned off.

[0046] As an optional embodiment, the linear compensation formula is y=kx+b, wherein y is the illuminance of the light source on the standard surface, x is the illuminance of the light source on the target surface, and k and b are compensation coefficients of the compensation formula.

[0047] Optionally, the linear compensation formula is y=kx+b, where y is the illuminance of the light source on the standard surface, x is the illuminance of the light source on the target surface, and k and b are compensation coefficients of the compensation formula. Two sets of illuminance data can be obtained. One set of illuminance data is the illuminance of the standard surface and the target surface when the preset light source is turned on, and the other set of illuminance data is the illuminance of the standard surface and the target surface when the preset light source is turned off. In this way, the preset light source only needs to emit one kind of light to obtain two sets of illuminance data. Substituting the two sets of illuminance data into the compensation formula in turn, the two compensation coefficients k and b can be obtained.

[0048] As an optional embodiment, the illuminance corresponding to the target light source to be detected is uploaded to the display terminal.

[0049] Optionally, the illuminance corresponding to the target light source to be detected may be uploaded to a display terminal, and a user may see the illuminance through the display terminal.

[0050] Here is a specific implementation method:

[0051] 1. The target illumination surface of the specified standard is a white smooth surface. The TSIM sensor (light sensor) is used for light intensity detection. The light intensity data detected by the TSIM sensor (light sensor) has nothing to do with the distance, and the light intensity data detected at each distance is the same. All light intensity values ​​should be normalized to the data measured on this surface.

[0052] 2. In the user's environment, after installing the TSIM sensor (light sensor) at the user's designated location, first lay a standard white smooth surface on the user's designated target surface, and use the TSIM sensor (light sensor) to test the illuminance of the user's lighting fixtures when they are turned off and on, and the illuminance data are lux1 and lux2. Remove the standard reflective surface, and then use the TSIM sensor to detect the illuminance of the user's lighting fixtures when they are turned off and on, and obtain the illuminance data lux3 and lux4.

[0053] 3. lux1 and lux2 are defined as the actual illumination of the target surface after normalization, and lux3 and lux4 are defined as the original illumination of the target surface. Taking the emerald green cortex reflective surface as an example, the original illumination data read by TSIM is compared with the data read by the white light reflective surface under the same conditions, and the compensation formula: y=kx+q is used to normalize the reflective surface data to the white light reflective surface. Among them, y represents the illumination value of the white light reflective surface, x represents the original illumination value of the emerald green cortex, and k and q are the coefficients of the normalization formula. After substituting the 4 data into the formula, 2 equations can be obtained. Solving the quadratic equations together can solve the coefficients k and q.

[0054] 4. The user can shine the light source to be detected on the target surface. After the original illuminance is compensated by the above compensation formula, the obtained target illuminance can be displayed on the display terminal for the user to view.

[0055] It should be noted that, for the above-mentioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present invention.

[0056] Through the description of the above implementation methods, those skilled in the art can clearly understand that the illumination calibration method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, disk, CD), including a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.
