Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
According to one aspect of the present invention, a window shade control system is provided for determining whether a window shade of a vehicle needs to be closed and generating a warning signal.
As shown in fig. 1, the window shade control system 100 includes a photographing module 110 and a processing module 120.
The shooting module 110 is used for shooting image data outside the vehicle. The camera module 110 may be a camera module installed at any position for capturing images outside the vehicle, for example, a camera module installed on any transparent glass inside the vehicle or a camera installed at any position outside the vehicle.
The vehicle exterior image data refers to image data shot under the influence of the vehicle exterior environment light, and can be images indicating the vehicle exterior environment light, or any type of data such as shooting parameters influenced by the vehicle exterior environment light and the like which can directly or indirectly indicate the intensity of the vehicle exterior environment light.
In order to adapt to shooting under different light environments, the existing shooting device needs to balance among multiple shooting parameters to obtain optimal image data. The more common shooting parameters include sensitivity, i.e., ISO value, aperture size, and shutter speed.
Sensitivity is a measure of the sensitivity of a negative to light, and a negative that is not sensitive requires a higher exposure to achieve the same image as a sensitive negative. The conventional shooting device can provide ISO 40-2000, preferably ISO3200 or ISO 6400. Higher sensitivity is more favorable for imaging in poor light environments.
Aperture refers to the size of the darkroom window. The larger the aperture, the larger the window, and the more light is transmitted into the window, which increases the corresponding exposure.
Shutter speed refers to the time the shutter is open. The slower the shutter speed, the longer the exposure time, and the more light penetrates, so that the exposure amount increases.
Of course, changes in any one of the ISO value, aperture and shutter time will have an effect on different aspects of the picture quality. Therefore, when the light changes, one or more of the ISO value, the aperture and the shutter time may change, but the change trend is relatively constant. For example, when the ambient light becomes strong, the ISO value decreases relatively, the aperture decreases relatively, the shutter speed increases relatively, and the exposure time becomes relatively short. Therefore, the change of any one shooting parameter of the three can indicate the change of the ambient light. Therefore, the intensity of sunlight can be judged by comparing shooting parameters of the image data shot in the natural environment, and the sun shade can be used for judging whether the sunlight is too strong or not and whether the sun shade needs to be pulled up or not in the scheme.
The processing module 120 is coupled to the photographing module 110, and is configured to acquire image data outside the vehicle, determine whether the sunshade needs to be closed based on the image data outside the vehicle, and generate a warning signal to prompt the sunshade to be closed in response to determining that the sunshade needs to be closed.
It can be understood that the closed sunshade described in the present case refers to a state in which the sunshade is set to block a window of a vehicle, i.e., "pull up the sunshade"; opening the sunshade means setting the sunshade in a state of not blocking the window, i.e. "opening the sunshade" in spoken language.
Further, the image data outside the vehicle captured by the capturing module 110 includes label information indicating capturing parameters, which at least includes capturing parameters that can be used to indicate the intensity of the ambient light, such as one or more of an ISO value, an aperture, and a shutter speed.
Preferably, the processing module 120 obtains tag information included in the image data outside the vehicle to determine whether the sunshade curtain needs to be closed according to the tag information.
More specifically, when the tag information includes only one photographing parameter, a lookup table or a relationship function regarding the photographing parameter and the light intensity may be set based on the correspondence between the one photographing parameter and the light intensity. The highest light intensity which does not damage human eyes and does not influence driving sight is set as a preset threshold value.
Preferably, after the processing module 120 obtains the shooting parameter in the tag information, the processing module 120 obtains the light intensity corresponding to the shooting parameter according to the comparison table or the relationship function, and in response to that the light intensity corresponding to the shooting parameter is greater than the preset threshold, the processing module 120 determines that the sunshade curtain needs to be closed.
It can be understood that, when the tag information includes a plurality of shooting parameters, the variation of the plurality of shooting parameters can be converted to one of the shooting parameters in advance based on the influence relationship among the plurality of shooting parameters, and then a comparison table or a relationship function between the plurality of shooting parameters and the light intensity is set based on the corresponding relationship between the one shooting parameter and the light intensity. The highest light intensity which does not damage human eyes and does not influence driving sight is set as a preset threshold value.
The processing module 120 may convert the plurality of shooting parameters into shooting parameters under a standard value after obtaining the plurality of shooting parameters, where the shooting parameters under the standard value only have one changed parameter value, and the rest of the shooting parameters are standard values. The processing module 120 determines the light intensity corresponding to the changed parameter value based on the comparison table or the relationship function, and determines that the sunshade screen needs to be closed in response to the light intensity corresponding to the parameter value being greater than a preset threshold.
Alternatively, the processing module 120 may perform image recognition on the vehicle exterior image data captured by the capturing module 110 to determine the light intensity indicated by the vehicle exterior image data. The specific image recognition method can be a neural network algorithm, a template matching method, a geometric transformation method and other image recognition methods which can recognize the intensity of the light in the image.
Preferably, the standard image under the highest light intensity that does not damage human eyes and does not affect driving sight line may be used as the preset standard image in advance, and the processing module 120 determines whether the light intensity indicated by the vehicle exterior image data is greater than the brightness of the preset standard image based on the brightness comparison between the vehicle exterior image data shot by the shooting module 110 and the preset standard image. In response to the light intensity indicated by the image data outside the vehicle being greater than the brightness of the preset standard image, the processing module 120 determines that the sunshade screen needs to be closed.
It will be appreciated that in response to determining that the shade needs to be closed, the processing module 120 generates an alert signal intended to trigger an action to close the shade.
In some embodiments, the warning message may be a reminder message for reminding the user to manually close the shade.
Specifically, the reminding information may be an expression similar to "strong sunlight, please close the sunshade screen", and may further specifically include the light intensity determined by the processing module 120 based on the tag information included in the image data or the light intensity value identified based on the image data.
Further, the reminding information can be sound reminding information or virtual picture reminding information.
The audible alert message may be a voice message played through a speaker of the vehicle. The virtual screen reminder information may be a virtual screen corresponding to the content of the reminder information displayed through a center control display screen of the vehicle so as to intuitively display the action of closing the sunshade.
In addition, in some highly automated vehicles, the warning signal may be a shade control signal that is used to close the shade.
In the case that the degree of automation of the vehicle is high, the processing module 120 may be a vehicle body controller, and when the vehicle body controller determines that the sunshade needs to be closed, generates a sunshade control signal to control the window sunshade to be closed.
In other cases, the processing module 120 may be integrated with the camera module 110 in a device, or the camera module 110 may be a camera for capturing images in an existing device, and the processing module 120 may be a module with processing function that is installed in a vehicle or a module with processing function that is already equipped in the vehicle.
According to another aspect of the present invention, there is provided a window shade control method for determining whether a window shade needs to be closed and generating a warning signal.
In one embodiment, as shown in FIG. 2, the method 200 for controlling a window covering includes steps S210-S230.
Wherein, step S210 is: and acquiring vehicle exterior image data.
The vehicle exterior image data refers to image data shot under the influence of the vehicle exterior environment light, and can be images indicating the vehicle exterior environment light, or any type of data such as shooting parameters influenced by the vehicle exterior environment light and the like which can directly or indirectly indicate the intensity of the vehicle exterior environment light.
The vehicle-exterior image data can be acquired from a shooting module arranged on a vehicle, or can be acquired from a communication module arranged on the vehicle (the communication module is communicated with other vehicle networks, network equipment or other roadside shooting modules to acquire the vehicle-exterior image data), or can be directly acquired from channels such as the vehicle networks, the other network equipment or other roadside shooting modules.
Step S220 is: whether the sunshade curtain needs to be closed is judged based on the image data outside the vehicle.
In order to adapt to shooting under different light environments, the existing shooting device needs to balance among multiple shooting parameters to obtain optimal image data. The more common shooting parameters include sensitivity, i.e., ISO value, aperture size, and shutter speed.
Sensitivity is a measure of the sensitivity of a negative to light, and a negative that is not sensitive requires a higher exposure to achieve the same image as a sensitive negative. The conventional shooting device can provide ISO 40-2000, preferably ISO3200 or ISO 6400. Higher sensitivity is more favorable for imaging in poor light environments.
Aperture refers to the size of the darkroom window. The larger the aperture, the larger the window, and the more light is transmitted into the window, which increases the corresponding exposure.
Shutter speed refers to the time the shutter is open. The slower the shutter speed, the longer the exposure time, and the more light penetrates, so that the exposure amount increases.
Of course, changes in any one of the ISO value, aperture and shutter time will have an effect on different aspects of the picture quality. Therefore, when the light changes, one or more of the ISO value, the aperture and the shutter time may change, but the change trend is relatively constant. For example, when the ambient light becomes strong, the ISO value decreases relatively, the aperture decreases relatively, the shutter speed increases relatively, and the exposure time becomes relatively short. Therefore, the change of any one shooting parameter of the three can indicate the change of the ambient light. Therefore, the intensity of sunlight can be judged by comparing shooting parameters of the image data shot in the natural environment, and the sun shade can be used for judging whether the sunlight is too strong or not and whether the sun shade needs to be pulled up or not in the scheme.
Further, the step S220 includes steps S221 to S222.
Wherein, step S221 is: and acquiring label information of the image data outside the vehicle.
It is understood that, in this embodiment, the vehicle exterior image data acquired in step S210 may only include the shooting parameters of the shooting device for shooting the vehicle exterior image at the time of shooting, that is, the tag information. The vehicle exterior image data may also include all data generated by the photographing device after photographing the vehicle exterior image, and the step S221 identifies the tag information included in the data.
The shooting parameters included in the tag information may be one or more of an ISO value, an aperture, and a shutter speed.
Step S222 is: and judging whether the sunshade curtain needs to be closed or not based on the label information.
Specifically, when the tag information includes only one shooting parameter indicating the light intensity, a comparison table or a relationship function relating to the shooting parameter and the light intensity may be set based on the correspondence between the one shooting parameter and the light intensity. The highest light intensity which does not damage human eyes and does not influence driving sight is set as a preset threshold value.
Further, after the shooting parameters in the tag information are obtained, the light intensity corresponding to the shooting parameters is obtained according to the comparison table or the relation function, and the sunshade curtain is judged to be closed in response to the fact that the light intensity corresponding to the shooting parameters is larger than the preset threshold value.
It can be understood that, when the tag information includes a plurality of shooting parameters, the variation of the plurality of shooting parameters can be converted to one of the shooting parameters in advance based on the response relationship between the plurality of shooting parameters, and then a comparison table or a relationship function between the plurality of shooting parameters and the light intensity is set based on the corresponding relationship between the one shooting parameter and the light intensity. The highest light intensity which does not damage human eyes and does not influence driving sight is set as a preset threshold value.
Furthermore, after the plurality of shooting parameters are obtained, the shooting parameters are converted into shooting parameters in a standard format, the shooting parameters in the standard format only have one changed parameter value, and the rest shooting parameters are standard values. And determining the light intensity corresponding to the changed parameter value based on the comparison table or the relation function, and judging that the sunshade curtain needs to be closed in response to the fact that the light intensity corresponding to the parameter value is larger than a preset threshold value.
Further, step S230 is: in response to a positive determination, an alert signal is generated that is intended to initiate an action to close the shade.
It will be appreciated that in some embodiments, the warning message may be a reminder message for reminding the user to manually close the shade.
Specifically, the reminding information may be an expression similar to "strong sunlight, please close the sunshade screen", and may further specifically include a light intensity value determined based on the tag information included in the image data.
Further, the reminding information can be sound reminding information or virtual picture reminding information.
The audible alert message may be a voice message played through a speaker of the vehicle. The virtual screen reminder information may be a virtual screen corresponding to the content of the reminder information displayed through a center control display screen of the vehicle so as to intuitively display the action of closing the sunshade.
In addition, in some highly automated vehicles, the warning signal may be a shade control signal that is used to close the shade.
In another embodiment, as shown in FIG. 3, the window shade control method 300 includes steps S310-S330.
Wherein, step S310 is: and acquiring vehicle exterior image data.
The vehicle exterior image data refers to image data shot under the influence of the vehicle exterior environment light, and can be images indicating the vehicle exterior environment light, or any type of data such as shooting parameters influenced by the vehicle exterior environment light and the like which can directly or indirectly indicate the intensity of the vehicle exterior environment light.
The vehicle-exterior image data can be acquired from a shooting module arranged on a vehicle, or can be acquired from a communication module arranged on the vehicle (the communication module is communicated with other vehicle networks, network equipment or other roadside shooting modules to acquire the vehicle-exterior image data), or can be directly acquired from channels such as the vehicle networks, the other network equipment or other roadside shooting modules.
Step S320 is: and judging whether the sunshade curtain needs to be closed or not based on the image data outside the vehicle.
Specifically, the light intensity indicated by the vehicle exterior image data may be determined by performing image recognition on the vehicle exterior image data acquired in step S310. The specific image recognition method can be a neural network algorithm, a template matching method, a geometric transformation method and other image recognition methods which can recognize the intensity of the light in the image.
Further, the standard image under the highest light intensity which does not damage human eyes and does not influence the driving sight line can be used as the preset standard image in advance, and whether the light intensity indicated by the vehicle exterior image data is larger than the brightness of the preset standard image or not is judged based on the brightness comparison between the acquired vehicle exterior image data and the preset standard image. Step S320 includes S321: and judging that the sunshade curtain needs to be closed in response to the fact that the light intensity indicated by the image data outside the vehicle is greater than the brightness of the preset standard image.
Further, step S330 is: in response to a positive determination, an alert signal is generated that is intended to initiate an action to close the shade.
It will be appreciated that in some embodiments, the warning message may be a reminder message for reminding the user to manually close the shade.
Specifically, the reminding information may be an expression similar to "strong sunlight, please close the sunshade screen", and may further specifically include a light intensity value determined based on the tag information included in the image data or include a light intensity value recognized based on the image data.
Further, the reminding information can be sound reminding information or virtual picture reminding information.
The audible alert message may be a voice message played through a speaker of the vehicle. The virtual screen reminder information may be a virtual screen corresponding to the content of the reminder information displayed through a center control display screen of the vehicle so as to intuitively display the action of closing the sunshade.
In addition, in some highly automated vehicles, the warning signal may be a shade control signal that is used to close the shade.
