Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method of a first embodiment of a method for spectrum sensing a user environment according to an embodiment of the present invention.
In a first embodiment, the method of spectrally detecting a user environment comprises:
step 101, acquiring ambient light information of an environment where a user is located through a light sensor, wherein the ambient light information at least comprises a spectrum, a color temperature, a color rendering and/or an illumination;
step 102, judging whether the environment where the user is located is indoor or outdoor according to the pre-stored environment light information of the indoor environment and the environment light information of the outdoor environment.
Preferably, the determining whether the environment where the user is located is indoor or outdoor according to the pre-stored ambient light information of the indoor environment and the ambient light information of the outdoor environment includes:
if the detected light of each wave band of the spectrum is uniform and the ultraviolet component is higher than a preset ultraviolet value, judging that the environment where the user is located is outdoor; or,
and if the detected light of each wave band of the spectrum is uniform and the infrared component is higher than the preset infrared value, judging that the environment where the user is located is outdoor.
Specifically, the first condition is spectral detection, light rays in each wavelength band of the spectrum of sunlight are relatively uniform, especially ultraviolet components are usually high, and other light components are not obviously strong or weak. The spectrum of the light mostly uses blue light emitted by the diode to excite the fluorescent powder due to the light emitting principle and the application mode, and the white light is mostly the fluorescent powder with three primary colors with high color rendering, but the ultraviolet components and the components with shorter wavelength are less. Sunlight has strong infrared rays which far exceed the infrared ray intensity of artificial lamplight, and the point is also obvious difference. In terms of weather conditions such as cloudy days and cloudy days, the ultraviolet rays have weak points only due to illumination, namely light and shade, but the infrared part is far larger than the light, and the frequency spectrum distribution is also more uniform than the light.
Preferably, the determining whether the environment where the user is located is indoor or outdoor according to the pre-stored ambient light information of the indoor environment and the ambient light information of the outdoor environment includes:
if the color rendering of the detected spectrum is within 75 to 90 of the preset color rendering range, judging that the environment where the user is located is indoor;
if the color rendering of the detected ambient light is within the preset color rendering range 98-100, it is determined that the environment where the user is located is outdoor.
Specifically, the color rendering of sunlight is defined as 100, the light sensation measurement has an error basically not lower than 98%, and most of market and family life lights have color rendering of basically 75-90, which is greatly different from natural light. Color rendering is also called color rendering index, and is a measure for restoring the real color of an object viewed under the light.
Preferably, the determining whether the environment where the user is located is indoor or outdoor according to the pre-stored ambient light information of the indoor environment and the ambient light information of the outdoor environment includes:
if the detected spectral illumination is not more than 2000 and the color temperature is not more than 6000K, judging that the environment where the user is located is indoor;
and if the detected ambient light illuminance exceeds 2000 and the detected color temperature exceeds 6000K, judging that the environment where the user is located is outdoor.
Specifically, as for the illumination and the color temperature, the difference is very large in the morning and evening according to the brightness, but the illumination of normal daily lamplight can only reach the standard, because the energy conservation is not too high, the artificial illumination basically cannot exceed 2000, the color temperature cannot exceed 6000K, but the color temperature and the illumination of sunlight can far exceed the value in most of the day, so that the auxiliary judgment can be realized.
By utilizing the parameters, whether the indoor lighting or the outdoor natural lighting is performed can be judged, the indoor and outdoor are distinguished, the GPS is started at any time interval according to the tested indoor and outdoor conditions, or the LBS positioning mode is switched to the GPS mode, the GPS does not need to try positioning all the time, and the electric quantity is wasted.
Furthermore, the method can be applied to function reminding of leaving the building or other indoor places according to the measured indoor and outdoor conditions, and compared with the method of simply judging whether reminding is carried out indoors or outdoors by positioning, the method can judge more accurately by combining the indoor reminding and the outdoor reminding.
In addition, at night, only time and elimination methods can be adopted, firstly, the method is distinguished from time points, whether a night judgment mode is started or not is judged, lights are generally turned on indoors according to the habit of people, if the illumination reaches certain intensity and other differences are obvious enough, the method is judged to be indoors, if the light is weak, the method is defaulted to be outdoors, GPS signals are started for trial, if the positioning cannot be carried out, the method is defaulted to be indoors in the same light mode, and if the light changes greatly, the method is judged again. The watch may be a terminal device such as a mobile phone, and the mobile phone is generally exposed to the environment when in use, so that the shielding is not considered.
The embodiment of the invention obtains the ambient light information of the environment where the user is located through a light sensor, wherein the ambient light information at least comprises a spectrum, a color temperature, a color rendering and/or an illumination; according to the pre-stored environment light information of the indoor environment and the environment light information of the outdoor environment, whether the environment where the user is located is indoor or outdoor is judged, and therefore the indoor and outdoor positioning is achieved by utilizing the difference between the outdoor natural light and the indoor light.
