The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The current technology is realized mainly based on the signal-to-noise ratio of the signal received by the sensor, which determines the accuracy of blood oxygen detection, but the current sensor has poor anti-interference characteristics to ambient light, because the light signal received by the detection device not only contains the transmitted light signal of pulse information, but also contains the background light signal in the measurement environment. So that the accuracy of the measured blood oxygen saturation is low.
In view of the above problems, embodiments of the present invention provide a blood oxygen measurement method and related apparatus, which are described in detail below with reference to the accompanying drawings.
Referring to fig. 1a, fig. 1a is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. As shown in the figure, the electronic device 10 includes a microscope lens 101, a light emitting module 102, a light supplementing module 103 and a blood oxygen measuring device 104, wherein the light emitting module 102 is used for illuminating a position to be measured, so that the microscope lens 101 can acquire clear and effective images, the light supplementing module 103 is used for supplementing light when the current measurement environment is insufficient, so that the images acquired by the microscope lens 101 are more accurate, the blood oxygen measuring device 104 controls the microscope lens 101, the light emitting module 102 and the light supplementing module 103 work, and the images from the microscope lens 101 are processed to obtain the blood oxygen saturation.
Another block diagram of the electronic device is shown in fig. 1b, where the electronic device 10 includes a processor 120, a memory 130, a communication interface 140, and one or more programs 131, where the one or more programs 131 are stored in the memory 130 and configured to be executed by the processor 120, and the one or more programs 131 include instructions for performing any of the following method embodiments. In a specific implementation, the processor 120 is configured to perform any one of the steps performed by the electronic device in the method embodiments described below, and when performing data transmission such as sending, optionally invokes the communication interface 140 to complete the corresponding operation.
Referring to fig. 2a, fig. 2a is a schematic flow chart of a blood oxygen measurement method according to an embodiment of the present application. The blood oxygen measuring device is applied to an electronic device, and as shown in the figure, the blood oxygen measuring method comprises the following steps:
s201, acquiring a blood oxygen measurement instruction;
s202, controlling the light emitting module to emit light according to the blood oxygen measurement instruction.
Wherein, the light emitting module can be a flash lamp of the electronic device.
S203, after the light emitting module emits light, determining whether the current test condition meets a preset condition.
The current test condition is used for indicating the test condition of the tested position under the irradiation of the light source corresponding to the light emitting module. The test conditions include lighting conditions for determining whether the background light of the current test environment affects the detection accuracy, and location conditions for indicating that the tested location, e.g. the tested location being the palm of the user, is not the optimal test location. In the case where the position condition is not satisfied, the user may be prompted to replace the measured position, or to replace the measured position with a finger. Particularly, when the current test condition is determined, the image during the current test can be acquired through a microscope lens or other cameras of the electronic device, then whether the position to be detected meets the position condition is determined according to the image, and if the position to be detected does not meet the position condition, the user can be prompted to move according to the image acquired in real time until the position meeting the condition is reached. For example, if the current measured position of the user is a palm, and the current measured position can be determined to be the palm through the acquired image, the user is prompted to move the electronic device upward until the measured position is a fingertip.
And S204, if the preset condition is not met, controlling the light supplementing module to emit light according to the current test condition.
The light supplementing module can comprise a plurality of light supplementing light sources, and the distance between the position of the light supplementing light source of the light supplementing module and the micro lens is smaller than a preset distance, so that the light supplementing light sources and the micro lens can form a nearby measurement relation. The electronic equipment can control all the light supplementing light sources to emit light according to the current test condition, and also can control one or more light supplementing light sources to emit light. In particular, the test condition at this time may be a light source condition.
S205, after the light supplementing module emits light, acquiring measurement data through the micro lens;
and S206, performing blood oxygen measurement according to the measurement data.
The measurement data may be a video with a preset duration acquired by the micro-lens. When blood oxygen measurement is carried out, the blood oxygen saturation is mainly calculated, so that a plurality of frames of pictures can be extracted according to videos to carry out data analysis, and the blood oxygen saturation is calculated. Particularly, after obtaining a plurality of frames of pictures, it is determined whether a data format corresponding to the plurality of frames of pictures is an RGB format, and if not, format conversion needs to be performed on the data corresponding to the plurality of frames of pictures to obtain measurement data in the RGB format. When blood oxygen measurement is carried out according to a multi-frame picture, the light intensity conversion after red light and infrared light irradiation can be simulated by using the R component and the B component in the RGB model, and then the blood oxygen saturation is obtained according to a blood oxygen saturation calculation formula.
It can be seen that, in this example, the electronic device obtains a blood oxygen measurement instruction, then controls the light emitting module to emit light according to the blood oxygen measurement instruction, determines whether the current test condition meets a preset condition after the light emitting module emits light, controls the light supplementing module to emit light according to the current test condition if the preset condition is not met, obtains measurement data through the microscope lens after the light supplementing module emits light, and finally performs blood oxygen measurement according to the measurement data. Therefore, the interference of ambient light during the blood oxygen measurement can be reduced, and the blood oxygen measurement accuracy is improved.
In one possible example, the controlling the light supplement module to emit light according to the current test condition includes: and controlling the supplementary lighting module to emit red light and/or infrared light according to the current test condition.
The light supplement module may include a red light source and an infrared light source. As shown in fig. 2b, fig. 2b is a schematic back view of an electronic device according to an embodiment of the present disclosure. The electronic device shown in the figure is loaded with a red light source and an infrared light source, the infrared light source can be 940nm infrared light source, and the red light source can be 660nm red light source. It should be noted that the shape of the fill-in light module may be annular or square, and fig. 2b is only one possible example.
Therefore, in this example, the light supplement module emits red light and/or infrared light according to the measurement condition, so that the interference of ambient light during blood oxygen measurement can be reduced, and the blood oxygen measurement precision can be improved.
In one possible example, the acquiring measurement data through the microscope lens includes: determining the distance between the microscope lens and a position to be detected; outputting prompt information under the condition that the distance is greater than a preset distance, wherein the prompt information is used for prompting a user to change the distance between the microscope lens and the position to be detected so as to enable the distance to be smaller than the preset distance; and acquiring measurement data through the microscope lens under the condition that the distance is smaller than the preset distance.
Wherein, in order to avoid the interference of external environment light to the measuring result to the greatest extent, need carry out the approach observation when using the microscope camera lens to carry out blood oxygen measurement, consequently need control the distance of microscope camera lens and surveyed position. In the measurement, the user uses the electronic device to photograph the measured position, so that the distance between the microscope lens and the measured position needs to be smaller than or equal to the preset distance in a prompting manner. The prompt message may be a voice prompt.
Therefore, in the embodiment, the distance between the microscope lens and the measured position is controlled, so that the microscope lens can be close to the observation during the blood oxygen measurement, and the blood oxygen measurement precision is improved.
In one possible example, the acquiring of the measurement data through the microscope lens includes: acquiring a multi-frame picture through the microscope lens; and determining data corresponding to a picture with a picture time sequence after the Nth frame picture as the measurement data, wherein the digital quantization value of each color channel corresponding to the Nth frame picture reaches a preset value.
The method comprises the steps of acquiring a real-time video through a micro lens, monitoring data of each frame of picture corresponding to the real-time video until a Digital Number (DN) value of each color channel reaches half of a saturation value, and determining the data corresponding to the subsequently acquired video as measurement data. In particular, when the measurement data is acquired, data corresponding to a preset number of frames of pictures after the nth frame of picture may be selected as the measurement data, for example, data corresponding to 5 frames or 10 frames of pictures after the nth frame of picture may be selected as the measurement data.
Therefore, in this example, the data corresponding to the picture frame that satisfies the condition is selected as the measurement data, which can improve the accuracy of the data for blood oxygen measurement, thereby improving the accuracy of the blood oxygen saturation measurement.
In one possible example, the determining whether the current test condition satisfies a preset condition includes: acquiring an environment image through the microscope lens to obtain pre-acquisition data; analyzing the current illumination environment according to the pre-collected data; and determining whether the current test condition meets a preset condition or not according to the current illumination environment.
The environment image includes a measured position, that is, the electronic device first acquires an image of the measured position after the light-emitting module emits light, so as to first determine whether the image in the scene meets the requirements of an image available for measurement.
Therefore, in the embodiment, whether light supplement is needed or not is determined according to the current illumination condition, so that the blood oxygen measurement precision can be ensured, and unnecessary energy consumption can be reduced.
In one possible example, the analyzing the current lighting environment according to the pre-collected data includes: determining the type of the ambient light of the ambient image according to the pre-acquired data; determining the ambient light frequency of the ambient image according to the pre-acquisition data; and determining the current illumination environment according to the type of the ambient light and the frequency of the ambient light.
Wherein, ambient light can cause interference to blood oxygen measurement, for example, in the environment such as outdoor, strong light irradiation, background light signal is greatly enhanced, baseline variation of blood oxygen signal can be caused, and measurement range is reduced. Therefore, the ambient light frequency and the ambient light type need to be determined according to the pre-collected data, so as to determine the current illumination environment. The ambient light type may be used to indicate a current photographing scene, including an indoor shadow scene, an indoor illumination scene, an outdoor shadow scene, an outdoor illumination scene, and the like. When the ambient light type is determined, the detected position image in the acquired ambient image may be extracted first, for example, the detected position is a fingertip, the fingertip image in the ambient image may be extracted first, then a color histogram is determined according to the fingertip image, then the color histogram is analyzed and data normalization is performed, and then the acquired analysis data is compared with the brightness template to obtain the current ambient light type. Determining a color histogram may create a histogram from the three dimensions of hue, saturation and brightness of an image.
Therefore, in this example, the current illumination environment is determined according to the type of the ambient light and the frequency of the ambient light, so that the accuracy of determining the current test condition can be improved, and the electronic device can more accurately determine to control the light supplement module.
In one possible example, the determining whether the current test condition satisfies a preset condition includes: acquiring an environment image through the microscope lens to obtain pre-acquisition data; processing the pre-collected data to obtain a signal-to-noise ratio; when the signal-to-noise ratio is larger than a preset value, determining that the current test condition meets the preset condition.
The blood oxygen measurement precision is mainly related to the signal-to-noise ratio of the signal received by the sensor, so that the current signal-to-noise ratio can be directly determined according to the pre-acquired data, and whether the preset condition is met or not is determined according to the signal-to-noise ratio. In particular, different preset values may be determined according to the number of frames of the picture used for calculating the signal-to-noise ratio, wherein the larger the number of picture frames, the higher the preset value.
Therefore, in this example, whether the preset condition is met or not is determined according to the signal-to-noise ratio, so that the accuracy of determining the current test condition can be improved, and the electronic device can more accurately determine to control the light supplement module.
