In the daily practical use of the electronic device by the user, the user cannot judge whether the current use environment meets the use condition of the electronic device. When a user uses the electronic device in an unknown liquid environment, irreparable damage can be caused to the mobile phone. For example, electronic equipment is used for photographing in seawater, and seawater with high salt content can corrode exposed positions such as a charging port of a mobile phone. If use electronic equipment in a hot spring swimming pool of high temperature, the high temperature can let waterproof rubber ring warp and lead to electronic equipment to intake, has reduced electronic equipment's safety in utilization.
Based on this, the embodiment of the present invention provides an information prompting method and an electronic device, which determine whether a liquid satisfies a preset usage environment condition by using a multispectral image of the liquid, and output a prompting message to remind a user when the liquid does not satisfy the preset usage environment condition, so as to improve the usage safety of the electronic device. The following detailed description is to be read with reference to specific embodiments and the drawings.
The principle of spectral imaging is described below. The surface color of an object is seen by people because the object selectively absorbs and reflects light of different wavelengths after the light from a light source (including the sun, electric lamps, etc.) reaches the object. While light rays that are not absorbed by the object or reflected by the object reach the viewer (e.g., a person or a camera), which analyzes and encodes the light rays to form a spectral image that is seen by the person.
The multispectral sensor covers a plurality of optical filters with different wave band transmittances on the pixel to realize one-time exposure and complete the acquisition of full-spectrum signals. Due to the nature of the object itself, the object selectively absorbs light, and thus the properties of the object can be expressed in a spectral image. The composition or structure (molecules, atoms) of different substances are different, so that substance identification, i.e. spectroscopic detection, can be performed on the basis of the spectroscopic image of the substance. Therefore, the multispectral sensor can be used for detecting different substances, such as water quality, medicines, wine, fruits, vegetables, grains and the like.
Fig. 1 is a schematic flow chart illustrating an information prompting method according to an embodiment of the present invention. As shown in fig. 1, the information prompting method provided in the embodiment of the present invention is applied to an electronic device, and includes the following steps:
in step 110, a multispectral image of the liquid is acquired by the multispectral sensor with the electronic device in the liquid.
And step 120, judging whether the liquid meets the preset use environment condition corresponding to the electronic equipment or not based on the multispectral image.
And step 130, if the liquid does not meet the preset use environment condition, outputting prompt information.
As one example, the output prompt may be a display prompt on a screen of the electronic device, or a motor vibration alert.
It should be noted that, if the liquid in which the electronic device is located meets the corresponding preset usage environment condition, the electronic device does not output the prompt message.
In the embodiment of the invention, the user can be reminded to stop using the electronic equipment in the liquid in which the electronic equipment is positioned in time by outputting the prompt message. In the embodiment of the invention, whether the liquid meets the preset use environment condition of the electronic equipment is automatically judged by utilizing the multispectral image of the liquid collected by the multispectral sensor, and the prompt information is output to prompt a user when the liquid does not meet the preset use environment condition, so that some use risks can be avoided in advance, and the use safety of the electronic equipment is improved. Moreover, manual operation of a user is not needed, and the efficiency of surveying the use environment of the electronic equipment is improved.
The specific implementation of each of steps 110 to 130 is described below.
The specific implementation of step 110 is described below. The multispectral sensor comprises an optical part and a control part. The optical portion of the multispectral sensor includes imaging optics and optical elements that divide the spectrum. The imaging optical element is used for imaging a shot object. The spectrally splitting optical element splits the incident beam into a plurality of filters. These filters have different spectral transmission ranges beyond which they are all reflective. Radiation sensitive elements are arranged in the radiation path of the partial beams behind these filters. For example, the radiation sensitive element may be a visible light detector, an infrared detector, an ultraviolet detector. The control part of the multispectral sensor is used for processing the signal output by the radiation sensitive element to obtain a spectral image of the shot object under each wave band, namely a multispectral image.
When the electronic equipment is in the liquid, the multispectral sensor is started and is controlled to collect multispectral images of the liquid, so that the multispectral sensor is prevented from being in a starting state all the time, resources can be saved, and cost is reduced.
The multispectral sensor can be used for acquiring spectral images of liquid where the electronic equipment is located under multiple wave bands at one time, namely rich characteristic information of the liquid can be acquired at one time, and the liquid detection efficiency is improved.
The specific implementation of step 120 is described below. In some embodiments, step 120 includes steps 1201 and 1202. Step 1201, determining characteristic information of the liquid by using the multispectral image of the liquid. And step 1202, judging whether the liquid meets a preset use environment condition or not based on the characteristic information of the liquid.
In the embodiment of the invention, the multispectral image comprises spectral images of liquids in which electronic equipment is located under different wave bands. Due to the fact that spectral reflection characteristics of different substance components in liquid where the electronic equipment is located are different, the multispectral images under different wave bands can reflect different characteristic information of the liquid. Thus, at least one characteristic information of the liquid may be determined by analyzing the multispectral image of the liquid.
Through utilizing the characteristic information of the liquid where the electronic equipment is located, whether the liquid meets the preset use environment condition of the electronic equipment or not is judged, and the accuracy of detecting the liquid can be improved.
As a specific example, the multispectral image of the liquid in which the electronic device is located includes a first spectral image of the liquid in the infrared band and a second spectral image of the liquid in the ultraviolet band. Wherein step 1201 includes: determining a temperature of the liquid based on the first spectral image; based on the second spectral image, a liquid type of the liquid is determined. That is, the characteristic information of the liquid in which the electronic device is located includes the temperature of the liquid and the liquid type of the liquid.
As an example, the preset usage environment condition may include a preset usage temperature range of the electronic device and a preset liquid type corresponding to the electronic device. And if the temperature of the liquid in which the electronic equipment is located exceeds the preset use temperature range of the electronic equipment, and/or if the liquid type of the liquid in which the electronic equipment is located is not the preset liquid type corresponding to the electronic equipment, determining that the liquid does not meet the preset use environment condition corresponding to the electronic equipment.
In other examples, the predetermined environmental conditions may further include a predetermined ph range, since liquids that are too acidic or too basic may also corrode the electronic device. The pH value of the liquid can be obtained by utilizing reflection spectrum images of the liquid under different wave bands and a pre-established analysis model between the reflection spectrum and the hydrogen ion concentration index (namely the pH value). Whether the liquid meets the preset environmental use condition is judged by judging whether the PH of the liquid is in the preset pH value range.
In other embodiments of the present invention, the predetermined environmental conditions may further include the absence of a predetermined corrosive composition. For example, some substances with strong oxidizing properties or some substances with toxic properties. By using the multispectral image of the liquid, it can be determined whether the liquid contains a predetermined substance component having corrosive properties. And if the liquid contains preset substance components with corrosion performance, determining that the liquid in which the electronic equipment is positioned does not meet the preset environmental use condition.
In still other embodiments of the present invention, the predetermined environmental conditions may further include a predetermined range of sand and stone contents, since sand and stones in the liquid may enter the electronic device through a gap (e.g., a charging port) of the electronic device. The sand content of the liquid can be obtained by using a multispectral image of the liquid. If the sand content of the liquid exceeds the preset sand content range, the liquid where the electronic equipment is located can be determined not to meet the preset using environment condition.
In some examples, the multispectral image includes spectral images of a liquid in which the electronic device is located at a plurality of different wavelength bands, and step S1201 includes: and for the spectral image under each waveband, determining characteristic information of the liquid, which is associated with the spectral image, by utilizing the gray value of at least one pixel point in the spectral image. On the basis of step 1201, step 1202 includes: and if one characteristic information of the liquid does not meet the preset characteristic condition corresponding to the characteristic information, determining that the liquid does not meet the preset use environment condition.
That is, different characteristic information of the liquid can be acquired by using spectral images of the liquid at different wavelength bands. And each piece of characteristic information has a corresponding preset characteristic condition.
For example, if the characteristic information of the liquid in which the electronic device is located is the temperature of the liquid, the preset characteristic condition corresponding to the characteristic information is a preset temperature range. If the characteristic information of the liquid in which the electronic equipment is located is the content of a certain substance component, the preset characteristic condition corresponding to the characteristic information is a preset content range corresponding to the substance component.
As a specific example, if the multispectral image includes a first spectral image of a liquid in which the electronic device is located in the infrared band and a second spectral image of the liquid in the ultraviolet band. For example, the infrared band may be about 700 nm to about 1000 nm, among others. The ultraviolet wavelength range is about 10 nm to 400 nm.
In some embodiments, in step 1201, the temperature corresponding to the gray value of each first pixel point in the at least one first pixel point may be determined by using the gray value of the at least one first pixel point in the first spectral image and the preset correspondence between the gray value and the temperature; and determining the temperature of the liquid based on the temperature corresponding to the gray value of each first pixel point.
In some embodiments of the present invention, the first target gray value may be determined based on a gray value of each first pixel point in the first spectral image. As an example, the first target gray-scale value is the highest gray-scale value among the gray-scale values of all the first pixel points. The first target gray value may also be an average of the gray values of all the first pixel points.
And then, matching the first target gray value with each gray value of a preset corresponding relation between the gray value and the temperature, and taking the temperature value corresponding to the gray value matched with the first target gray value in the corresponding relation as the temperature value of the liquid where the electronic equipment is located.
In other embodiments, a plurality of first pixel points may be selected first, and then the temperature value corresponding to the gray value of each of the first pixel points in the plurality of first pixel points is determined based on the corresponding relationship between the preset gray value and the temperature. And then taking the average value of the temperature values corresponding to the gray values of the first pixel points as the temperature value of the liquid where the electronic equipment is located.
The plurality of first pixel points may be randomly selected, or a plurality of first pixel points having a gray value greater than a first preset gray threshold may be selected, which is not limited herein.
In step 1201, determining the chloride ion content and the nitrate content corresponding to the gray value of each second pixel point in the at least one second pixel point by using the gray value of the at least one second pixel point in the second spectral image, the preset correspondence between the gray value and the chloride ion content, and the preset correspondence between the gray value and the nitrate content; determining the content of nitrate and the content of chloride ions in the liquid based on the content of chloride ions and the content of nitrate corresponding to the gray value of each second pixel point; the liquid type of the liquid is determined based on the nitrate content and the chloride ion content in the liquid.
In some embodiments of the present invention, the second target gray-scale value may be determined based on a gray-scale value of each second pixel point in the second spectral image. As an example, the second target gray-scale value is the highest gray-scale value among the gray-scale values of all the second pixel points. The first target gray value may also be an average of the gray values of all the second pixel points.
And then, matching the second target gray value with each gray value of a preset corresponding relation between the gray value and the chloride ion content, and taking the chloride ion content corresponding to the gray value matched with the second target gray value in the corresponding relation as the chloride ion content of the liquid in which the electronic equipment is positioned.
Similarly, the second target gray value is matched with each gray value of the preset corresponding relation between the gray value and the nitrate content, and the nitrate content corresponding to the gray value matched with the second target gray value in the corresponding relation is used as the nitrate content of the liquid in which the electronic equipment is located.
In other embodiments, a plurality of second pixel points may be selected first. The plurality of second pixel points may be randomly selected, or a plurality of second pixel points having a gray value greater than a second preset gray threshold may be selected, which is not limited herein.
And then, determining the chloride ion content corresponding to the gray value of each second pixel point in the plurality of second pixel points based on the corresponding relation between the preset gray value and the chloride ion content. And then taking the average value of the chloride ion content corresponding to the gray value of each second pixel point as the chloride ion content of the liquid in which the electronic equipment is positioned.
Similarly, the nitrate content corresponding to the gray value of each second pixel point in the plurality of second pixel points is determined based on the corresponding relation between the preset gray value and the nitrate content. And then taking the average value of the nitrate content corresponding to the gray value of each second pixel point as the nitrate content of the liquid in which the electronic equipment is positioned.
And then, matching the nitrate content and the chloride ion content in the liquid in which the electronic equipment is positioned with preset nitrate content and preset chloride ion content respectively corresponding to a plurality of preset liquid types, and taking the preset liquid type corresponding to the preset nitrate content matched with the nitrate content in the liquid in which the electronic equipment is positioned and the preset nitrate content matched with the chloride ion content in the liquid in which the electronic equipment is positioned as the liquid type of the liquid in which the electronic equipment is positioned. As one example, the liquid type may be seawater or fresh water.
If the preset liquid type corresponding to the electronic equipment is fresh water, if the liquid type of the liquid in which the electronic equipment is located is detected to be seawater and/or the temperature of the liquid in which the electronic equipment is located exceeds the preset use temperature range of the electronic equipment, determining that the liquid does not meet the preset use environment condition of the electronic equipment, and outputting prompt information.
As shown in fig. 2, another embodiment of the present invention provides an information prompting method, which includes step 101, step 102, step 110, step 120, and step 130. The detailed implementation of step 110, step 120 and step 130 is not described herein.
Through the acquired environmental parameters of the electronic equipment, whether the electronic equipment is in the liquid can be automatically judged in advance, manual operation of a user is not needed, and the detection efficiency of the liquid is improved.
In some embodiments, the environmental parameter of the electronic device includes an air pressure value and a touch location corresponding to a touch input on a screen of the electronic device. Step 102 includes determining whether the air pressure value is within a preset air pressure range, and determining whether the touch position is a preset position; and if the air pressure value is not within the preset air pressure range and the touch position is the preset position, determining that the electronic equipment is in the liquid.
By utilizing the characteristic that the touch screen of the electronic equipment reacts when encountering liquid, whether the electronic equipment is in the liquid can be judged by utilizing the touch position corresponding to the touch input on the screen of the electronic equipment.
As one example, touch location of a touch input on an electronic device may be detected using touch sensing technology. As one example, the touch sensing technology may be a capacitive sensing technology. By utilizing the human body current induction, a coupling capacitor is formed between the finger of the user and the surface of the touch screen of the electronic equipment. For high frequency currents, the capacitor is a direct conductor, and the finger draws a small current away from the contact. The current flows from the electrodes at the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. And accurately calculating the four current proportions to obtain the position of the touch point in a preset coordinate system.
However, when the electronic device is placed in water, the water also becomes a conductor, and at this time, the whole touch screen forms a whole conductive surface, and the obtained position is the position of the whole screen area of the electronic device in the preset coordinate system.
Therefore, the position of the whole screen area of the electronic equipment in the preset coordinate system can be used as the preset position. If the detected touch position of the touch input corresponds to the preset position, the electronic equipment is located in the liquid.
Because the air pressure values of the electronic equipment in the liquid and the electronic equipment in the air are different, whether the electronic equipment is in the liquid or not can be judged according to the air pressure values. The electronic device may use its own barometer to collect the barometric pressure.
The electronic equipment is judged whether to be in the liquid or not by integrating two factors of the air pressure value and the touch position corresponding to the touch input on the screen of the electronic equipment, so that the judgment accuracy can be improved.
In other embodiments, the environmental parameter may also include a connectivity status of all pins in a charging port of the electronic device. When a pin used for charging the electronic equipment in a charging port of the electronic equipment is in a connected state, the electronic equipment is charged. And if the pin for transmitting the data in the charging port of the electronic equipment is in a connected state, transmitting the data by using the electronic equipment.
However, if all the pins in the charging port of the electronic device are in the connected state, it represents that liquid enters into the charging port, and all the pins of the electronic device are triggered to be in the connected state, that is, the electronic device may be in the liquid. Therefore, whether all pins in the charging port of the electronic equipment are in a connected state can be judged, and whether the electronic equipment is in liquid can be further accurately judged.
