As shown in fig. 1, the invention discloses a low-power-consumption positioning method based on double-frequency combination, which comprises the following steps:

First, infrared sensor acquires infrared induction information by performing data processing using infrared rays. Infrared sensors are often used for non-contact temperature measurement, gas composition analysis and nondestructive inspection, for example, thermal imaging images of the surface temperature of a human body are measured remotely by using the infrared sensors, and the position of the abnormal temperature can be found. The first distance information is the distance between the human body and the vehicle-mounted multimedia equipment, which is measured by an infrared sensor; the thermal radiation information is temperature information of one or more positions in a predetermined direction and angle measured by an infrared sensor, and may be thermal image information measured by an infrared sensor. That is, whether an object is within a service area set by the multimedia device can be judged through the distance information; the object in the service area set by the multimedia equipment can be analyzed whether the object is in a proper temperature range or not through the heat radiation information; and the practical scene is synthesized again, and the object with proper temperature in the service area set by the multimedia equipment can be considered as a passenger. When the passenger is identified, the working state of the multimedia device can be set.
Then, when it is determined that there is a passenger in front of the in-vehicle multimedia device, an image of the passenger is captured by a camera of the in-vehicle multimedia device. And processing and analyzing the image of the passenger to obtain the information of the eye image. Analyzing the eye image to obtain second distance information and visual angle information, wherein the second distance information is the distance from the upper eyelid to the lower eyelid in the eye image information and is used for judging the opening condition of the passenger; the visual angle information is the angle of the eye pupil, and whether the eyes of the passengers look at the vehicle-mounted multimedia equipment can be judged. The working state of the multimedia device is set by the eye opening condition and the visual angle state of the passenger.
Fig. 2 is a flowchart showing a method for controlling the judgment of the infrared sensing information.
According to an embodiment of the present invention, as shown in fig. 2, the setting of the unmanned mode or the passenger mode is determined according to the first distance information and the heat radiation information, specifically:
s202, judging whether the first distance information exceeds a preset first distance threshold value;
if the first distance information does not exceed the preset first distance threshold value; executing S204, and judging whether the heat radiation information exceeds a preset heat radiation threshold value; if yes, executing S208, and setting the current mode as a passenger mode; if not, executing S206, and setting the current mode as an unmanned mode;
If the first distance information exceeds the preset first distance threshold, executing S206, and setting the current mode as an unmanned mode;
when the unmanned mode is set, the multimedia screen is closed and the loudspeaker output is closed; and when the passenger mode is set, the multimedia screen is closed and the loudspeaker output is started.
The infrared sensor is used for carrying out data processing by utilizing infrared rays to obtain infrared induction information, and the first distance information and the heat radiation information are obtained through calculation. First, the first distance information can be used to determine the distance of the nearest object in front of the multimedia device. The criterion for determining the presence or absence of an object in front of the multimedia device is set as to whether the measured distance of the nearest object exceeds a first distance threshold. That is, the case where the measured distance is set so as not to exceed the first distance threshold value indicates that the multimedia device is preceded by an object; the measured distance exceeding the first distance threshold indicates that no object is in front of the multimedia device. For example, a distance threshold of 0.5 meters is set, and when the measured distance does not exceed 0.5 meters, it indicates that there is an object within a distance of 0.5 meters in front of the multimedia device; when the measured distance exceeds 0.5 meters, it means that there is no object within a distance of 0.5 meters in front of the multimedia device. The thermal radiation information may be temperature information at one or more positions in a predetermined direction and angle measured by an infrared sensor, or thermal image information measured by an infrared sensor. The method for judging whether the heat radiation object is a human body can be used for measuring temperature information of one or more positions of a designated direction and angle, and setting the heat radiation threshold value to be in a temperature range of 35-42 ℃ for example. If the measured temperature value is within the threshold temperature range, it is considered to be a human body; if the measured temperature is outside the threshold temperature range, then a non-human body is deemed. The method for judging whether the thermal radiation object is a human body can also judge whether the object to be detected can be identified as the human body by judging whether the thermal image is processed and identified according to the thermal image processed by the infrared sensor as thermal radiation information and drawing the outline of the thermal image.
When no object is determined in front of the multimedia device, the multimedia device is set to be in an unmanned mode, namely, the multimedia screen display and the loudspeaker output are closed, so that the purpose of saving electricity is achieved. When an object is determined to exist in front of the multimedia device and the object is determined to be a non-human body, the object is indicated to be not a service object of the multimedia device, and the multimedia device is set to be in an unmanned mode, namely, the multimedia screen display and the loudspeaker output are closed, so that the purpose of saving electricity is achieved. When an object is determined to be in front of the multimedia device and the object is determined to be a human body, the multimedia device is set to a passenger mode, and the multimedia screen is not started and the loudspeaker output is started by default, so that the object of the multimedia audio service exists at the moment.
Fig. 3 is a flowchart showing a method for controlling the judgment of the infrared sensing information.
According to an embodiment of the present invention, as shown in fig. 3, the setting of the hearing mode or the audio-visual mode is determined according to the second distance information and the viewing angle information, specifically:
s302, judging whether the second distance information exceeds a preset second distance threshold value;
if the second distance information exceeds the preset second distance threshold value; s304 is executed to judge whether the visual angle information is located in a preset space range; if yes, executing S308, and setting the current mode as an audio-visual mode; if not, then S306 is performed, setting the current mode to auditory mode.
When the hearing mode is set, the brightness value of the multimedia screen is adjusted to the lowest value, and the output of the loudspeaker is kept; when the audio-visual mode is set, the brightness value of the multimedia screen is adaptively adjusted, and the output of the loudspeaker is kept.
When it is determined that a passenger is in front of the in-vehicle multimedia device, an image of the passenger is captured by a camera of the multimedia device. And processing and analyzing the image of the passenger to obtain information of the eye image, and analyzing the eye image to obtain second distance information and visual angle information. First, the second distance information is the distance from the upper eyelid to the lower eyelid in the eye image information for judging the open eye condition of the passenger. When the second information distance exceeds the set threshold value, the passenger is indicated to be in an eye-open state; and when the second information distance exceeds the set threshold value, the passenger is indicated to be in a closed-eye state. For example, assuming that the set second distance threshold is 5mm, when the resulting distance from the upper eyelid to the lower eyelid is greater than 5mm, it is indicated to be in an open-eye state; when the obtained distance from the upper eyelid to the lower eyelid is not more than 5mm, it indicates an eye-closing state. Then, the viewing angle information is the angle of the eye pupil viewing direction, and when the passenger is in the open eye state, whether the passenger's eyes are looking at the screen can be determined by determining whether the area of the passenger's eye pupil viewing direction is within the screen area. When the passengers look at the screen, the passengers are identified to need to perform man-machine interaction; when the eyes of the passenger do not look at the screen, the passenger is deemed to not need to provide service for the screen.
When the passenger is in the eye-closed state, it means that the passenger does not need to operate the screen, remains in the passenger mode, keeps the screen in the off state and turns on the speaker output, that is, retains the function of sound output. The display screen is closed to save electric energy, and the audio output function is kept to meet the requirement of passengers for listening to music with eyes closed. When the passenger is in an eye-open state and does not look at the on-vehicle processor display screen, the hearing mode is set, the display screen at this time is set to the state where the brightness is the lowest, and the speaker output is maintained. When the passengers do not look at the screen, the screen is dimmed, so that the purpose of saving electric energy is achieved. When the passengers are in the eye opening state and look at the display screen, the display screen is set to be in an audio-visual mode so as to meet the requirement of human-computer interaction of the passengers. At this time, the brightness of the display screen is adaptively adjusted along with the ambient brightness, so as to improve the use experience of passengers.
According to the embodiment of the invention, the self-adaptive adjustment of the brightness value of the multimedia screen is specifically as follows:
when in the audiovisual mode;
acquiring ambient brightness information; setting a multimedia screen brightness value according to the environment brightness information;
acquiring time information; and setting the multimedia screen to enter a daytime mode or a night mode according to the time information.
When the device processes the audio-visual mode, the camera of the vehicle-mounted multimedia device is used for collecting the ambient brightness, and the brightness value of the screen is adaptively adjusted according to the ambient brightness. Under the condition of higher ambient brightness, the brightness value of the screen is increased, and clear display service is provided for passengers; under the condition of lower ambient brightness, the brightness value of the screen is reduced, the dazzling feeling is reduced, and the purpose of saving electric energy is achieved. In addition, the screen is set to a daytime mode or a night-time mode according to the local time. The daytime mode can be set to be a brighter color such as white, and the night mode can be set to be a darker color such as black, so that the viewing experience of passengers is improved.
According to an embodiment of the present invention, further comprising:
when in the passenger mode;
when the second distance information does not exceed a preset second distance threshold value and the multimedia screen is detected to be actively activated:
starting a multimedia screen and acquiring the eye image information;
obtaining the second distance information according to the eye image information;
recording a first duration of time that the second distance information does not exceed the preset second distance threshold;
Determining whether the first duration exceeds a first duration threshold;
if yes, closing the multimedia screen.
It should be noted that, when the passenger is determined to be in a closed-eye state and the multimedia display screen is detected to be actively touched and activated at the same time: first, the display screen is turned on, and an operation of periodically acquiring eye image information is performed, for example, acquisition analysis is performed on an eye image every 100 milliseconds. Obtaining second distance information according to the eye image information, and recording the first duration time when the second distance information does not exceed the preset second distance threshold value. The first duration is a time when the passenger remains in the eye-closed state, that is, a time when the passenger remains in the eye-closed state after the multimedia screen is touched. If the duration of the passenger maintaining the eye-closed state exceeds a set first duration threshold, for example, the duration of the eye-closed state exceeds 3 seconds, the passenger is determined to be misoperation of the screen, and no screen use requirement is required by the passenger. The multimedia screen is closed so as to achieve the purposes of not influencing the rest of passengers and saving electric energy.
According to an embodiment of the present invention, further comprising:
when in the passenger mode;
when the second distance information does not exceed a preset second distance threshold value and the multimedia screen is detected to be actively activated for a plurality of times:
Starting a multimedia screen and acquiring the eye image information;
obtaining the second distance information according to the eye image information;
and adjusting the second distance threshold according to the second distance information.
It should be noted that, in some passengers, the distance between the upper eyelid and the lower eyelid is smaller than that of the average passenger, which is commonly called as small eyes. A small-eye passenger may have a situation in which he is physiologically open-eye but is deemed closed by the multimedia device. When the passenger is identified as the eye-closed state and the multimedia display screen is detected to be activated by multiple active touches, the method comprises the following steps: first, the display screen is turned on, and an operation of periodically acquiring eye image information is performed, for example, acquisition analysis is performed on an eye image every 100 milliseconds. The multiple active touches may be activated continuously for 2 times or more within a certain period of time, for example, the display screen is touched continuously for 2 times within 3 seconds. The active touch may also be a screen that is woken up again in a short time after a closing operation is performed after the screen is woken up, for example, the screen is woken up by the first touch of the screen, and the multimedia device is activated again within 2 seconds after the screen is closed when the multimedia device detects that the screen is closed. In this case, the multimedia printer recognizes the passenger as a small-eye passenger, and at this time, adjusts the second distance threshold based on the second distance information obtained from the eye image. For example, the original second distance threshold value is set to 2.5mm based on the average value of the second distance information obtained before being 3mm after the eye-open state is determined to be a small-eye passenger by 5mm.
It is worth mentioning that the method further comprises:
in the case of the video play state,
acquiring the eye image information;
obtaining the second distance information and the visual angle information according to the eye image information;
recording a second duration that the second distance information does not exceed a preset second distance threshold or the viewing angle information is not within the preset spatial range;
determining whether the second duration exceeds a second duration threshold;
if the video playing state exceeds the preset value, the video playing state is exited.
It should be noted that the second duration is a duration in which the passenger is in a closed-eye state or is not looking at the screen when the multimedia device is in a movie playing state.

and if the variation amplitude does not exceed the preset variation threshold, adjusting the output volume of the loudspeaker according to the loudspeaker volume adjusting mode set by the user.
It should be noted that, when the passenger is in the passenger mode, but the acquisition of the eye image information fails, it means that there is a shielding object, such as a sunglasses and an eyeshade, in front of eyes of the passenger. And judging the change amplitude conditions of the first distance information and the heat radiation information, wherein the change amplitude conditions are used for judging whether the passenger still needs human-computer interaction when wearing the sunglasses or whether the passenger is in a rest state when wearing the eyeshade.

Fig. 4 shows a block diagram of a control system for an induction type vehicle-mounted medium according to the present invention.
As shown in fig. 4, the invention discloses a control system 4 of an induction type vehicle-mounted medium, which comprises a memory and a processor, wherein the memory comprises a control method program of the induction type vehicle-mounted medium, and the control method program of the induction type vehicle-mounted medium realizes the following steps when being executed by the processor:
Acquiring infrared induction information;
obtaining first distance information and heat radiation information according to the infrared induction information;
according to the first distance information and the heat radiation information, setting a current mode as an unmanned mode or a passenger mode;
when the passenger mode state is the passenger mode state, acquiring eye image information;
obtaining second distance information and visual angle information according to the eye image information;
and setting the current mode as an auditory mode or an audiovisual mode according to the second distance information and the visual angle information.
First, infrared sensor acquires infrared induction information by performing data processing using infrared rays. Infrared sensors are often used for non-contact temperature measurement, gas composition analysis and nondestructive inspection, for example, thermal imaging images of the surface temperature of a human body are measured remotely by using the infrared sensors, and the position of the abnormal temperature can be found. The first distance information is the distance between the human body and the vehicle-mounted multimedia equipment, which is measured by an infrared sensor; the thermal radiation information is temperature information of one or more positions in a predetermined direction and angle measured by an infrared sensor, and may be thermal image information measured by an infrared sensor. That is, whether an object is within a service area set by the multimedia device can be judged through the distance information; the object in the service area set by the multimedia equipment can be analyzed whether the object is in a proper temperature range or not through the heat radiation information; and the practical scene is synthesized again, and the object with proper temperature in the service area set by the multimedia equipment can be considered as a passenger. When the passenger is identified, the working state of the multimedia device can be set.
Then, when it is determined that there is a passenger in front of the in-vehicle multimedia device, an image of the passenger is captured by a camera of the in-vehicle multimedia device. And processing and analyzing the image of the passenger to obtain the information of the eye image. Analyzing the eye image to obtain second distance information and visual angle information, wherein the second distance information is the distance from the upper eyelid to the lower eyelid in the eye image information and is used for judging the opening condition of the passenger; the visual angle information is the angle of the eye pupil, and whether the eyes of the passengers look at the vehicle-mounted multimedia equipment can be judged. The working state of the multimedia device is set by the eye opening condition and the visual angle state of the passenger.
According to the embodiment of the invention, the passenger mode is judged to be entered according to the first distance information and the heat radiation information, specifically:
judging whether the first distance information exceeds a preset first distance threshold value or not;
if the first distance information does not exceed the preset first distance threshold value; judging whether the heat radiation information exceeds a preset heat radiation threshold value or not; if yes, setting the current mode as a passenger mode; if not, setting the current mode as an unmanned mode;
and if the first distance information exceeds the preset first distance threshold value, setting the current mode as an unmanned mode.
When the unmanned mode is set, the multimedia screen is closed and the loudspeaker output is closed; and when the passenger mode is set, the multimedia screen is closed and the loudspeaker output is started.
The infrared sensor is used for carrying out data processing by utilizing infrared rays to obtain infrared induction information, and the first distance information and the heat radiation information are obtained through calculation. First, the first distance information can be used to determine the distance of the nearest object in front of the multimedia device. The criterion for determining the presence or absence of an object in front of the multimedia device is set as to whether the measured distance of the nearest object exceeds a first distance threshold. That is, the case where the measured distance is set so as not to exceed the first distance threshold value indicates that the multimedia device is preceded by an object; the measured distance exceeding the first distance threshold indicates that no object is in front of the multimedia device. For example, a distance threshold of 0.5 meters is set, and when the measured distance does not exceed 0.5 meters, it indicates that there is an object within a distance of 0.5 meters in front of the multimedia device; when the measured distance exceeds 0.5 meters, it means that there is no object within a distance of 0.5 meters in front of the multimedia device. The thermal radiation information may be temperature information at one or more positions in a predetermined direction and angle measured by an infrared sensor, or thermal image information measured by an infrared sensor. The method for judging whether the heat radiation object is a human body can be used for measuring temperature information of one or more positions of a designated direction and angle, and setting the heat radiation threshold value to be in a temperature range of 35-42 ℃ for example. If the measured temperature value is within the threshold temperature range, it is considered to be a human body; if the measured temperature is outside the threshold temperature range, then a non-human body is deemed. The method for judging whether the thermal radiation object is a human body can also judge whether the object to be detected can be identified as the human body by judging whether the thermal image is processed and identified according to the thermal image processed by the infrared sensor as thermal radiation information and drawing the outline of the thermal image.
When no object is determined in front of the multimedia device, the multimedia device is set to be in an unmanned mode, namely, the multimedia screen display and the loudspeaker output are closed, so that the purpose of saving electricity is achieved. When an object is determined to exist in front of the multimedia device and the object is determined to be a non-human body, the object is indicated to be not a service object of the multimedia device, and the multimedia device is set to be in an unmanned mode, namely, the multimedia screen display and the loudspeaker output are closed, so that the purpose of saving electricity is achieved. When an object is determined to be in front of the multimedia device and the object is determined to be a human body, the multimedia device is set to a passenger mode, and the multimedia screen is not started and the loudspeaker output is started by default, so that the object of the multimedia audio service exists at the moment.
According to an embodiment of the present invention, the setting of the hearing mode or the audio-visual mode according to the second distance information and the viewing angle information includes:
the method comprises the following steps:
judging whether the second distance information exceeds a preset second distance threshold value or not;
if the second distance information exceeds the preset second distance threshold value; judging whether the visual angle information is positioned in a preset space range or not; if yes, setting the current mode as an audio-visual mode; if not, setting the current mode as an auditory mode;
When the hearing mode is set, the brightness value of the multimedia screen is adjusted to the lowest value, and the output of the loudspeaker is kept.
When the hearing mode is set, the brightness value of the multimedia screen is adjusted to the lowest value, and the output of the loudspeaker is kept; when the audio-visual mode is set, the brightness value of the multimedia screen is adaptively adjusted, and the output of the loudspeaker is kept.
When it is determined that a passenger is in front of the in-vehicle multimedia device, an image of the passenger is captured by a camera of the multimedia device. And processing and analyzing the image of the passenger to obtain information of the eye image, and analyzing the eye image to obtain second distance information and visual angle information. First, the second distance information is the distance from the upper eyelid to the lower eyelid in the eye image information for judging the open eye condition of the passenger. When the second information distance exceeds the set threshold value, the passenger is indicated to be in an eye-open state; and when the second information distance exceeds the set threshold value, the passenger is indicated to be in a closed-eye state. For example, assuming that the set second distance threshold is 5mm, when the resulting distance from the upper eyelid to the lower eyelid is greater than 5mm, it is indicated to be in an open-eye state; when the obtained distance from the upper eyelid to the lower eyelid is not more than 5mm, it indicates an eye-closing state. Then, the viewing angle information is the angle of the eye pupil viewing direction, and when the passenger is in the open eye state, whether the passenger's eyes are looking at the screen can be determined by determining whether the area of the passenger's eye pupil viewing direction is within the screen area. When the passengers look at the screen, the passengers are identified to need to perform man-machine interaction; when the eyes of the passenger do not look at the screen, the passenger is deemed to not need to provide service for the screen.
When the passenger is in the eye-closed state, it means that the passenger does not need to operate the screen, remains in the passenger mode, keeps the screen in the off state and turns on the speaker output, that is, retains the function of sound output. The display screen is closed to save electric energy, and the audio output function is kept to meet the requirement of passengers for listening to music with eyes closed. When the passenger is in an eye-open state and does not look at the on-vehicle processor display screen, the hearing mode is set, the display screen at this time is set to the state where the brightness is the lowest, and the speaker output is maintained. When the passengers do not look at the screen, the screen is dimmed, so that the purpose of saving electric energy is achieved. When the passengers are in the eye opening state and look at the display screen, the display screen is set to be in an audio-visual mode so as to meet the requirement of human-computer interaction of the passengers. At this time, the brightness of the display screen is adaptively adjusted along with the ambient brightness, so as to improve the use experience of passengers.
According to the embodiment of the invention, the self-adaptive adjustment of the brightness value of the multimedia screen is specifically as follows:
when in the audiovisual mode;
acquiring ambient brightness information; setting a multimedia screen brightness value according to the environment brightness information;
acquiring time information; and setting the multimedia screen to enter a daytime mode or a night mode according to the time information.
When the device processes the audio-visual mode, the camera of the vehicle-mounted multimedia device is used for collecting the ambient brightness, and the brightness value of the screen is adaptively adjusted according to the ambient brightness. Under the condition of higher ambient brightness, the brightness value of the screen is increased, and clear display service is provided for passengers; under the condition of lower ambient brightness, the brightness value of the screen is reduced, the dazzling feeling is reduced, and the purpose of saving electric energy is achieved. In addition, the screen is set to a daytime mode or a night-time mode according to the local time. The daytime mode can be set to be a brighter color such as white, and the night mode can be set to be a darker color such as black, so that the viewing experience of passengers is improved.
According to an embodiment of the present invention, further comprising:
when in the passenger mode;
when the second distance information does not exceed the preset second distance threshold value and the multimedia screen is detected to be actively activated, the method comprises the following steps:
starting a multimedia screen and acquiring the eye image information;
obtaining the second distance information according to the eye image information;
recording a first duration of time that the second distance information does not exceed the preset second distance threshold;
Determining whether the first duration exceeds a first duration threshold;
if yes, closing the multimedia screen.
It should be noted that, when the passenger is determined to be in a closed-eye state and the multimedia display screen is detected to be actively touched and activated at the same time: first, the display screen is turned on, and an operation of periodically acquiring eye image information is performed, for example, acquisition analysis is performed on an eye image every 100 milliseconds. Obtaining second distance information according to the eye image information, and recording the first duration time when the second distance information does not exceed the preset second distance threshold value. The first duration is a time when the passenger remains in the eye-closed state, that is, a time when the passenger remains in the eye-closed state after the multimedia screen is touched. If the duration of the passenger maintaining the eye-closed state exceeds a set first duration threshold, for example, the duration of the eye-closed state exceeds 3 seconds, the passenger is determined to be misoperation of the screen, and no screen use requirement is required by the passenger. The multimedia screen is closed so as to achieve the purposes of not influencing the rest of passengers and saving electric energy.
According to an embodiment of the present invention, further comprising:
when in the passenger mode;
when the second distance information does not exceed the preset second distance threshold value and the multimedia screen is detected to be actively activated for a plurality of times:
Starting a multimedia screen and acquiring the eye image information;
obtaining the second distance information according to the eye image information;
and adjusting the second distance threshold according to the second distance information.
It should be noted that, in some passengers, the distance between the upper eyelid and the lower eyelid is smaller than that of the average passenger, which is commonly called as small eyes. A small-eye passenger may have a situation in which he is physiologically open-eye but is deemed closed by the multimedia device. When the passenger is identified as the eye-closed state and the multimedia display screen is detected to be activated by multiple active touches, the method comprises the following steps: first, the display screen is turned on, and an operation of periodically acquiring eye image information is performed, for example, acquisition analysis is performed on an eye image every 100 milliseconds. The multiple active touches may be activated continuously for 2 times or more within a certain period of time, for example, the display screen is touched continuously for 2 times within 3 seconds. The active touch may also be a screen that is woken up again in a short time after a closing operation is performed after the screen is woken up, for example, the screen is woken up by the first touch of the screen, and the multimedia device is activated again within 2 seconds after the screen is closed when the multimedia device detects that the screen is closed. In this case, the multimedia printer recognizes the passenger as a small-eye passenger, and at this time, adjusts the second distance threshold based on the second distance information obtained from the eye image. For example, the original second distance threshold value is set to 2.5mm based on the average value of the second distance information obtained before being 3mm after the eye-open state is determined to be a small-eye passenger by 5mm.
It is worth mentioning that the method further comprises:
