Technical Field
The invention relates to a vehicle accessory inspection method, in particular to a vehicle lamp replacement reminding method and a vehicle lamp replacement reminding device.
Background
With the great improvement of living standard, automobiles are the first choice of private travel tools, and the holding amount of private automobiles is greatly improved.
Driving at night is also an option due to the popularity of private cars. However, the vehicle driving at night lacks natural environment light, and the brightness and the penetrability of the illuminating lamp are very high when the vehicle is driven at high speed. However, there is still a phenomenon that no street lamp is installed on the expressway or even a part of the urban highways, so in order to ensure the safety of driving at night, the car lamp plays an important role as the eyes of the car. With the development of automobile science and technology, the variety of automobile headlamps is also continuously improved, and halogen headlamps and the existing laser headlamps are sequentially applied to different automobile types, but different types of headlamp lamps have the advantages and disadvantages of the lamps and have limited service life.

However, there are few cases where the lamp is repaired while the vehicle is being repaired. It is often the case that the vehicle lamp is found by the naked eye of the user to have a reduced or no brightness.

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 invention, a vehicle lamp replacement reminding method is provided for judging whether a vehicle lamp of a vehicle needs to be replaced and generating a reminding message to remind a user of replacement when the vehicle lamp needs to be replaced.
In one embodiment, as shown in fig. 1, a method 100 for reminding a lamp replacement includes steps S110 to S130.
Wherein, S110 is: when at least one vehicle lamp of the vehicle is in an on state, image data of an irradiation area of the at least one vehicle lamp is acquired.
The irradiation area refers to a coverage area of the lamp light of the vehicle lamp when the vehicle lamp is in an on state, and the range size of the coverage area indicates the action range of the lamp light of the vehicle lamp. It can be understood that the current state of the car light can be judged through the irradiation effect of the car light in the irradiation area, for example, the brightness of the car light is judged through the definition degree of the object in the image data, the penetrability of the car light is judged through the distance of the object shot in the image data, and the like.
In the prior art, most of the car lights on the car are dispersedly arranged at two end positions of the car head or the car tail, namely four corner positions of the car. Although there may be a light overlapping region between the illumination regions of the lamps disposed at the respective positions, there are differences in the disposed positions and illumination angles of the respective lamps, and there still exists a single illumination region or a key action region for each lamp, and the image data of these regions can be used as a basis for determining the state of the corresponding lamp.
As shown in fig. 2, the illumination range of the illumination lamp disposed at a of one end of the vehicle head is Q1+ Q2, and the illumination range of the illumination lamp disposed at B of the other end of the vehicle head is Q3+ Q2, where the overlapping area is Q2. When only A, B headlights are on, Q1 is the single illumination area of the lighting at a and Q2 is the single illumination area of the lighting at B. Thus, the image data of the region Q1 can be acquired for determining whether the illumination lamp disposed at a is in a normal state, and the image data of the region Q3 can be acquired for determining whether the illumination lamp disposed at B is in a normal state.
Further, the positions of the lamps reflected by the captured image data are different depending on the positions at which the respective imaging devices are installed in the vehicle. Step S110 may therefore also include steps S111 to S114.
S111 is as follows: and responding to the arrangement of the at least one car lamp at the car head position, and acquiring image data shot by a front camera device of the car.
The area enclosed by the dashed line box S1 in fig. 2 is the "vehicle head position", and includes positions at any part of the vehicle head of the vehicle, and is used for setting a vehicle lamp for irradiating the front of the vehicle head or the front of the vehicle head side. The front camera device is a camera device for shooting the front of the vehicle head. It can be understood that the front in this case is relative to the vehicle tail, the vehicle tail is the rear of the vehicle head, and the direction away from the vehicle tail is the front of the vehicle head, that is, the direction pointed by the arrow C shown in fig. 2 is the front.
It can be understood that whether one or more vehicle lamps are in the on state, as long as any one or more vehicle lamps are in the vehicle head position, the image data shot by the front camera device needs to be acquired.
S112 is as follows: and identifying the image data of the irradiation area of the at least one vehicle lamp from the image data shot by the front camera device.
According to the type of the car lamps arranged at the car head position and the attributes of the car lamps, images shot by the front camera device are divided into a plurality of areas, and each car lamp corresponds to at least one area. Preferably, the image data of the individual irradiation area of each vehicle lamp can be used as the image data of the irradiation area of the vehicle lamp. It can be understood that when there is no single irradiation area for a vehicle lamp, the important irradiation area of the vehicle lamp can also be used as the image data of the irradiation area of the vehicle lamp. The accent illumination area refers to an area on which the main light of the vehicle lamp acts.
It is understood that such area division may be divided differently according to the kind of the lamps simultaneously turned on, the difference of the action areas, and the difference of the number of lamps when turned on.
S113 is: and responding to the situation that the at least one vehicle lamp is arranged at the tail of the vehicle, and acquiring image data shot by a rear camera device of the vehicle.
Similar to the definition of the vehicle head position, the area enclosed by the dashed box S2 in fig. 2 is the "vehicle tail position", and includes a position at any position of the vehicle tail of the vehicle, and is used for setting a vehicle lamp that irradiates the rear of the vehicle tail or the rear of the vehicle tail. The rear camera means is a camera for photographing the rear of the vehicle.
It can be understood that, whether there are one or more vehicle lights in the on state, as long as there are any one or more vehicle lights in the rear position, it is necessary to acquire the image data captured by the rear camera.
S114 is: the image data of the irradiation area of the at least one vehicle lamp is identified from the image data captured by the rear camera.
Similarly, the image shot by the rear camera device is divided into a plurality of areas according to the types of the car lights arranged at the tail positions of the cars and the attributes of the car lights, and each car light corresponds to at least one area. Preferably, the image data of the individual irradiation area of each vehicle lamp can be used as the image data of the irradiation area of the vehicle lamp. It can be understood that when there is no single irradiation area for a vehicle lamp, the important irradiation area of the vehicle lamp can also be used as the image data of the irradiation area of the vehicle lamp. The accent illumination area refers to an area on which the main light of the vehicle lamp acts.
It is understood that such area division may be divided differently according to the kind of the lamps simultaneously turned on, the difference of the action areas, and the difference of the number of lamps when turned on.
It can also be understood that when the types or the number of the lamps arranged at the head position and the tail position of the vehicle are different, the division rule of the image data shot by the rear camera and the division rule of the image data shot by the front camera can be different.
Preferably, when the vehicle is started, the image data of the irradiation area of each vehicle lamp can be acquired one by one for state analysis. It is also possible to simultaneously turn on one type of vehicle lights arranged in various directions, such as the low beams arranged at four corners of the vehicle, when the vehicle is started, to acquire image data of the illuminated areas of all the low beams for performing state analysis on all the low beams.
It can be understood that the auxiliary function of most car lights at night is far greater than that of the day, so that more preferably, the image data of the car light in the on state in the corresponding irradiation area can be acquired at night or in dark days to be used as the judgment basis of the car light.
It will also be appreciated that the means for acquiring image data mounted on the vehicle is typically switched on at least during the travel of the vehicle, and therefore the above process can also be synchronized during the travel, so that no additional time is required to perform the vehicle light condition test immediately after the vehicle has been started or stopped.
S120 is: and judging whether the at least one vehicle lamp needs to be replaced or not based on the image data of the irradiation area of the at least one vehicle lamp and the corresponding reference data.
It can be understood that, more simply, the image data of the irradiation area of the vehicle lamp in the normal operation state is used as the reference data. Preferably, the historical image data of each type of vehicle lamp in the normal working state is acquired at different times in different weathers in each season to serve as the reference data. Preferably, the image data of the irradiation area of the vehicle lamp can be acquired in the same season and at the same time in the same weather, and the image data is compared with the historical image data to analyze whether the vehicle lamp meets the standard of the historical image data.
Alternatively, when the vehicle leaves the factory, the manufacturer may obtain standard image data of the irradiation area of each type of vehicle lamp in a standard light environment as preset image data, and store the preset image data in a database in the vehicle, where the preset image data may be used as reference data for determining the state of the vehicle lamp.
Preferably, the acquired image data of the irradiation area of the at least one vehicle lamp may be subjected to brightness recognition.
Correspondingly, the step S120 includes: and in response to the fact that the brightness indicated by the image data of the irradiation area of the vehicle lamp is lower than the brightness indicated by the corresponding reference data, judging that the vehicle lamp is in an abnormal working state and needs to be replaced.
It is understood that the reference data may also be a preset brightness threshold value, and the brightness value indicated by the image data of the irradiation area of the vehicle lamp is compared with the preset brightness threshold value to determine whether the vehicle lamp is in a normal operation state.
On the other hand, in order to adapt to photographing in different light environments, the conventional photographing apparatus needs to balance among a plurality of photographing parameters to obtain optimal image data. Common shooting parameters include sensitivity, i.e., ISO value, and aperture value 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 brightness is low, the ISO value is relatively high, the aperture is relatively large, the shutter speed is relatively slow, and the exposure time is relatively long. Therefore, the change of any one of the three shooting parameters can indicate the change of the ambient brightness. Therefore, the image data shot under the same natural environment can judge the intensity of the auxiliary light through the comparison of the shooting parameters, and can be used for judging whether the vehicle lamp is in a normal working state and needs to be replaced.
However, this method is only suitable for the individual acquisition of the image data of the irradiation area of each vehicle lamp, i.e. turning on one vehicle lamp to be tested, acquiring the image data of the irradiation area of the vehicle lamp, and acquiring the shooting parameters of the image data for judging whether the vehicle lamp is in a normal state.
S130 is as follows: in response to the at least one vehicle light requiring replacement, generating a reminder message to remind a user to replace the at least one vehicle light.
It can be understood that the low beam, high beam, fog light, etc. on the vehicle can all adopt the method to judge whether there is loss or damage.
Further, the reminding information includes the position of the vehicle lamp to be replaced and the type thereof.
Preferably, step S130 further includes: and controlling a central control display screen or an instrument display screen of the vehicle to display the generated reminding information so that a user can replace the vehicle lamp according to the content of the reminding information.
Optionally, step S130 may further include: and controlling a loudspeaker of the vehicle to play the reminding information in a voice mode so as to inform the user of the reminding information under the condition of not attracting the driving sight of the user.
It can be understood that the reminding information can inform the user through the display of the central control display screen or the instrument display screen and the voice playing of the loudspeaker, and can also inform the user through any one of the three modes of the display of the central control display screen or the instrument display screen and the voice playing of the loudspeaker.
While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the methodologies are not limited by the order of acts, as some acts may, in accordance with one or more embodiments, occur in different orders and/or concurrently with other acts from that shown and described herein or not shown and described herein, as would be understood by one skilled in the art.
According to another aspect of the invention, a vehicle lamp replacement reminding device is provided for judging whether a vehicle lamp of a vehicle needs to be replaced and generating a reminding message to remind a user of replacement when the vehicle lamp needs to be replaced.
In one embodiment, as shown in FIG. 3, a vehicle light change reminder device includes a memory 310 and a processor 320.
The memory 310 may be used to store computer programs.
A processor 320 is coupled to the memory 310, the processor 320 configured to: when at least one vehicle lamp of the vehicle is in a starting state, acquiring image data of an irradiation area of the at least one vehicle lamp; judging whether the at least one vehicle lamp needs to be replaced or not based on the image data of the irradiation area of the at least one vehicle lamp and the corresponding reference data; in response to the at least one vehicle light requiring replacement, generating a reminder message to remind a user to replace the at least one vehicle light.
The irradiation area refers to a coverage area of the lamp light of the vehicle lamp when the vehicle lamp is in an on state, and the range size of the coverage area indicates the action range of the lamp light of the vehicle lamp. It can be understood that the current state of the car light can be judged through the irradiation effect of the car light in the irradiation area, for example, the brightness of the car light is judged through the definition degree of the object in the image data, the penetrability of the car light is judged through the distance of the object shot in the image data, and the like.
In the prior art, most of the car lights on the car are dispersedly arranged at two end positions of the car head or the car tail, namely four corner positions of the car. Although there may be a light overlapping region between the illumination regions of the lamps disposed at the respective positions, there are differences in the disposed positions and illumination angles of the respective lamps, and there still exists a single illumination region or a key action region for each lamp, and the image data of these regions can be used as a basis for determining the state of the corresponding lamp.
As shown in fig. 2, the illumination range of the illumination lamp disposed at a of one end of the vehicle head is Q1+ Q2, and the illumination range of the illumination lamp disposed at B of the other end of the vehicle head is Q3+ Q2, where the overlapping area is Q2. When only A, B headlights are on, Q1 is the single illumination area of the lighting at a and Q2 is the single illumination area of the lighting at B. Thus, the image data of the region Q1 can be acquired for determining whether the illumination lamp disposed at a is in a normal state, and the image data of the region Q3 can be acquired for determining whether the illumination lamp disposed at B is in a normal state.
Further, the positions of the lamps reflected by the captured image data are different depending on the positions at which the respective imaging devices are installed in the vehicle. The processor 320 is therefore further configured to: responding to the arrangement of the at least one car lamp at the car head position, and acquiring image data shot by a front camera device of the car; and identifying the image data of the irradiation area of the at least one vehicle lamp from the image data shot by the front camera device.
The area enclosed by the dashed line box S1 in fig. 2 is the "vehicle head position", and includes positions at any part of the vehicle head of the vehicle, and is used for setting a vehicle lamp for irradiating the front of the vehicle head or the front of the vehicle head side. The front camera device is a camera device for shooting the front of the vehicle head. It can be understood that the front in this case is relative to the vehicle tail, the vehicle tail is the rear of the vehicle head, and the direction away from the vehicle tail is the front of the vehicle head, that is, the direction pointed by the arrow C shown in fig. 2 is the front.
It can be understood that whether one or more vehicle lamps are in the on state, as long as any one or more vehicle lamps are in the vehicle head position, the image data shot by the front camera device needs to be acquired.
According to the type of the car lamps arranged at the car head position and the attributes of the car lamps, images shot by the front camera device are divided into a plurality of areas, and each car lamp corresponds to at least one area.

The accent illumination area refers to an area on which the main light of the vehicle lamp acts.
It is understood that such area division may be divided differently according to the kind of the lamps simultaneously turned on, the difference of the action areas, and the difference of the number of lamps when turned on.
For a setting in a rear of the vehicle position, the processor 320 is further configured to: responding to the situation that the at least one vehicle lamp is arranged at the tail position of the vehicle, and acquiring image data shot by a rear camera device of the vehicle; and identifying image data of the irradiation area of the at least one vehicle lamp from the image data shot by the rear camera device.
Similar to the definition of the vehicle head position, the area enclosed by the dashed box S2 in fig. 2 is the "vehicle tail position", and includes a position at any position of the vehicle tail of the vehicle, and is used for setting a vehicle lamp that irradiates the rear of the vehicle tail or the rear of the vehicle tail.

Preferably, the historical image data of each type of vehicle lamp in the normal working state is acquired at different times in different weathers in each season to serve as the reference data. Preferably, the image data of the irradiation area of the vehicle lamp can be acquired in the same season and at the same time in the same weather, and the image data is compared with the historical image data to analyze whether the vehicle lamp meets the standard of the historical image data.
Alternatively, when the vehicle leaves the factory, the manufacturer may obtain standard image data of the irradiation area of each type of vehicle lamp in a standard light environment as preset image data, and store the preset image data in a database in the vehicle, where the preset image data may be used as reference data for determining the state of the vehicle lamp.
Preferably, the acquired image data of the irradiation area of the at least one vehicle lamp may be subjected to brightness recognition.
Correspondingly, the processor 320 may be configured to: and in response to the fact that the brightness indicated by the image data of the irradiation area of the vehicle lamp is lower than the brightness indicated by the corresponding reference data, judging that the vehicle lamp is in an abnormal working state and needs to be replaced.
It is understood that the reference data may also be a preset brightness threshold value, and the brightness value indicated by the image data of the irradiation area of the vehicle lamp is compared with the preset brightness threshold value to determine whether the vehicle lamp is in a normal operation state.
On the other hand, in order to adapt to photographing in different light environments, the conventional photographing apparatus needs to balance among a plurality of photographing parameters to obtain optimal image data. Common shooting parameters include sensitivity, i.e., ISO value, and aperture value 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 brightness is low, the ISO value is relatively high, the aperture is relatively large, the shutter speed is relatively slow, and the exposure time is relatively long. Therefore, the change of any one of the three shooting parameters can indicate the change of the ambient brightness. Thus, the processor in this case may also be configured to: the image data shot under the same natural environment judges the intensity of the auxiliary light through the comparison of shooting parameters, and can be used for judging whether the vehicle lamp is in a normal working state and needs to be replaced.
However, this method is only suitable for the individual acquisition of the image data of the irradiation area of each vehicle lamp, i.e. turning on one vehicle lamp to be tested, acquiring the image data of the irradiation area of the vehicle lamp, and acquiring the shooting parameters of the image data for judging whether the vehicle lamp is in a normal state.
It can be understood that the low beam, high beam, fog light, etc. on the vehicle can all adopt the method to judge whether there is loss or damage.
Further, the reminding information includes the position of the vehicle lamp to be replaced and the type thereof.
Preferably, the processor is further configured to: and controlling a central control display screen or an instrument display screen of the vehicle to display the generated reminding information so that a user can replace the vehicle lamp according to the content of the reminding information.
Optionally, the processor may be further configured to: and controlling a loudspeaker of the vehicle to play the reminding information in a voice mode so as to inform the user of the reminding information under the condition of not attracting the driving sight of the user.
It can be understood that the reminding information can inform the user through the display of the central control display screen or the instrument display screen and the voice playing of the loudspeaker, and can also inform the user through any one of the three modes of the display of the central control display screen or the instrument display screen and the voice playing of the loudspeaker.
