Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent human-vehicle interaction, and in particular to a control system and method for preventing accidental triggering of B-pillar backlights. Background Technology
[0002] As the automotive industry further develops towards intelligence, more and more humanized, intelligent, and personalized functions are appearing in cars. Whether it's traditional car manufacturers or emerging new energy vehicle companies, they are all focusing on applying technologies such as big data, artificial intelligence, and the Internet of Things to their current products. Based on these technologies, they aim to better meet various consumer needs, enhance the driving and riding experience, and improve the interaction between people and cars, thereby enhancing the overall user experience.
[0003] Currently, a key function for enhancing human-vehicle interaction is illuminating door lights when a passenger prepares to enter the vehicle. This feature typically involves placing a light source under the door or rearview mirror, which turns on when the passenger opens the door. However, this method is ineffective because passengers usually enter the vehicle almost instantly after the door opens, making it difficult to observe the specific content displayed by the light. Since there are many reasons for door opening, the welcome lights may be frequently activated, and if the door needs to be open for an extended period, the welcome lights may remain constantly on, resulting in energy waste and reduced light source lifespan. Furthermore, this method lacks a target selection process, leading to poor accuracy and targeting, and the displayed content is very limited. Summary of the Invention

The system includes: a signal acquisition module 101, an image acquisition module 102, a machine vision module 103, a display control module 104, and a display module 105; wherein,
[0062] The signal acquisition module 101 is used to acquire the first position information of the sensing key.
[0063] The image acquisition module 102 is used to acquire image information of the exterior of the vehicle and send the image information to the machine vision module.

[0065] Specifically, it receives image information sent by the image acquisition module; compares the pre-stored target image with the image information to select the first passenger; and / or,

[0068] Based on the first location information of the sensor key, determine the first target person corresponding to the first location information from the image information;
[0069] The first target person is identified as the first passenger.
[0070] Preferably, after placing the image information in the same coordinate system as the first location information of the sensing key, the position in the image information that is the same as the first location information is determined based on the first location information, and the corresponding first target person is found.
[0071] Preferably, the first passenger is the driver of the vehicle.
[0072] Preferably, the first preset range can be a circular range with a radius of 10 meters centered on the center of the target vehicle.
[0073] The display control module 104 is used to generate a control signal and send it to the display module 105 when the first passenger and / or the second passenger are within a second preset range, based on the screening results for the first passenger and / or the second passenger.
[0074] Preferably, the second preset range can be a circular range with a radius of 2 meters centered on the center of the target vehicle.
[0075] The display module 105 is used to turn on the B-pillar backlight to display preset information according to the control signal.
[0076] Specifically, the display module is further used for:
[0077] The B-pillar backlight displays preset information via a display module.
[0078] Preferably, the B-pillar backlight uses a display module, and the content displayed on the display module can be controlled by a separate display signal. The specific display content can be preset and controlled through various methods such as the vehicle's infotainment system and a smart terminal's app, and is not limited here.
[0079] The B-pillar backlight anti-mistriggering control system provided in this embodiment includes: a signal acquisition module, an image acquisition module, a machine vision module, a display control module, and a display module; wherein, the signal acquisition module is used to acquire first location information of the induction key; the image acquisition module is used to acquire image information of the exterior of the vehicle and send the image information to the machine vision module; the machine vision module is used to compare the received image information with a pre-stored target image within a first preset range, and combine it with the first location information of the induction key to determine a first occupant; within the first preset range, it determines the travel route, travel speed, and travel target of the person outside the vehicle based on the image information, and filters out a second occupant; the display control module is used to generate a control signal and send it to the display module when the first occupant and / or the second occupant are within a second preset range, based on the filtering results of the first occupant and / or the second occupant; the display module is used to turn on the B-pillar backlight to display preset information according to the control signal.

By adjusting the printed cover or control display module, the specific content displayed by the B-pillar backlight can be more flexibly selected, better meeting the personalized needs of different users.
[0080] Based on machine vision module 103, there exists a method for screening first passengers, such as... Figure 2 As shown, Figure 2 A flowchart illustrating a first passenger screening method according to an embodiment of the present invention is shown;
[0081] The method includes the following steps:
[0082] Step S201: Extract target image features based on pre-stored target images.
[0083] Step S202: Extract all features of the image to be inspected from the image information.
[0084] Step S203: Calculate the similarity score between each feature of the image to be inspected and the feature of the target image in turn, and determine whether the similarity score is greater than the preset threshold.
[0085] Specifically, if yes, proceed to step S204; otherwise, proceed to step S205.
[0086] In step S204, if the obtained similarity score is greater than the preset threshold, the recognition is successful, the person corresponding to the image information is identified as the first passenger, and the recognition stops.
[0087] In step S205, if the obtained similarity score is not greater than the preset threshold, the recognition fails, and the similarity judgment is performed on the features of the next image to be detected.
[0088] Specifically, if the identification fails, return to step S203.
[0089] According to the above method, machine vision technology can be used to pre-store the facial image of the first passenger and then use facial recognition to filter and determine the first passenger from the acquired image information around the vehicle. This can greatly improve the accuracy and speed of screening the first passenger. At the same time, the above method also takes into account the situation where the first passenger does not carry a keyless entry device, that is, the purpose of accurately screening the first passenger can be achieved using only machine vision technology, thus improving the system's compatibility.
[0090] Based on machine vision module 103, there exists a second passenger screening method, such as... Figure 3 As shown, Figure 3 A flowchart illustrating a second passenger screening method according to an embodiment of the present invention is shown; the method includes the following steps:
[0091] Step S301: Based on the image information, obtain the travel route of the first passenger and the travel routes of other passengers in the image information within a preset time period.
[0092] Step S302: Compare the travel routes of other personnel with the travel route of the first passenger; determine whether the travel routes of other personnel are similar to the travel route of the first passenger.
[0093] Specifically, within a preset time period, the location information of the second target person and the first passenger at multiple corresponding times is extracted, and the distance between the second target person and the first passenger at each time is calculated; wherein, the second target person refers to other persons besides the first passenger.
[0094] Determine whether the distance between the second target person and the first passenger is less than the first preset distance at each time point;
[0095] If so, determine that the second target person's travel route is similar to the first passenger's travel route, and execute step S303;
[0096] If not, it is determined that the travel route of the second target person is not similar to the travel route of the first passenger, and step S304 is executed.
[0097] Preferably, the preset time period can be 20 seconds, and the multiple corresponding times can be 5 times; that is, the location information of 5 times is selected within 20 seconds for distance determination.
[0098] Step S303: Determine that the corresponding person is the second passenger.
[0099] Step S304: Determine that the corresponding person is not the second passenger.
[0100] Furthermore, based on the machine vision module 103, there exists another second passenger screening method, such as... Figure 4 As shown, Figure 4 A flowchart illustrating a second passenger screening method according to another embodiment of the present invention is shown; the method includes the following steps:
[0101] Step S401: Based on the image information, obtain the magnitude and direction of the current movement speed of the second target person, and determine its movement target within the image range.
[0102] Step S402: If the second target person's travel target is a user vehicle, then when the distance between the second target person and the user vehicle is less than a second preset distance, determine whether the travel speed of the second target person is less than a preset speed.
[0103] Specifically, if yes, proceed to step S403; otherwise, proceed to step S404.
[0104] Preferably, a second preset distance;
[0105] Step S403: Determine that the corresponding person is the second passenger.
[0106] Step S404: Determine that the corresponding person is not the second passenger.
[0107] Based on the two methods mentioned above, using machine vision technology, the vehicle's passengers can be quickly, scientifically, and accurately identified by comparing the travel routes of other people in the image with the driver's travel route, as well as by determining the travel targets and speeds of other people. This effectively avoids the B-pillar backlights from accidentally turning on when other people pass by the vehicle, preventing them from lighting up frequently, greatly reducing energy consumption, and making the system more energy-efficient and environmentally friendly.

[0110] The voice control submodule 506 is used to verify identity based on preset sound information, and wake up the voice control submodule after successful verification, and then control the display module according to further voice content from the user.

[0125] The similarity scores between each feature of the image to be inspected and the feature of the target image are calculated sequentially, and it is determined whether the similarity scores are greater than a preset threshold.
[0126] If the obtained similarity score is greater than the preset threshold, the recognition is successful, the person corresponding to the image information is identified as the first passenger, and the recognition stops.
[0127] If the obtained similarity score is not greater than the preset threshold, the recognition fails, and the similarity judgment is performed on the features of the next image to be detected.
[0128] Specifically, based on the image information, the travel route of the first passenger and the travel routes of other people in the image information within a preset time period are obtained;

[0132] Preferably, within a preset time period, the location information of the second target person and the first passenger at multiple corresponding times is extracted, and the distance between the second target person and the first passenger at each time is calculated; wherein, the second target person refers to persons other than the first passenger;
[0133] Determine whether the distance between the second target person and the first passenger is less than the first preset distance at each time point;
[0134] If so, then the movement route of the second target person is determined to be similar to that of the first passenger.
[0135] If not, then it is determined that the travel route of the second target person is not similar to the travel route of the first passenger.
[0136] Specifically, based on the image information, the magnitude and direction of the second target person's current movement speed are obtained to determine their movement target within the image range;

By acquiring the location of the proximity key and external image information, and based on pre-stored driver images, machine vision technology is used to filter the external image information and combine it with the proximity key's location information to more accurately identify the driver. Furthermore, after identifying the driver, machine vision technology compares the movement paths of other people in the image with the driver's path, and determines the movement targets and speeds of other people to scientifically and accurately identify the vehicle's passengers. The B-pillar backlights are only activated when the driver and passengers are close to the vehicle. Thus, by accurately filtering the driver and passengers from the surrounding image information, the backlight activation is more targeted, effectively preventing accidental activation of the B-pillar backlights when other people pass by the vehicle. Furthermore, by only activating the B-pillar backlights when the driver and passengers are very close to the vehicle, they are prevented from remaining illuminated for extended periods, significantly reducing energy consumption and making the system more energy-efficient and environmentally friendly. In addition, the B-pillar backlights can also be controlled via voice recognition, smart key, or an app, increasing user convenience and operational options.
