Detailed Description
The application provides a child safety riding reminding method and device, vehicle-mounted equipment and a readable storage medium, and aims to improve riding safety of a low-age child as much as possible by providing a judging and reminding mechanism based on whether the low-age child rides on a safety seat.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for reminding a child of taking a car safely, according to an embodiment of the present invention, an execution subject of each of the following steps in the embodiment is an on-board device disposed in a car, and the method is to identify whether a child of a low age who is a member of the car is seated in a child safety seat by the on-board device according to the execution of the following steps, and to improve the taking safety of the child of the low age through appropriate prompt information. The flow chart shown in fig. 1 comprises the following steps:
s101: acquiring identity information of members in the vehicle;
the method comprises the steps that the identity information of the members in the vehicle is acquired by the vehicle-mounted equipment.
The vehicle-mounted device may obtain the identity information in a plurality of ways, for example, the vehicle-mounted member identification system may directly obtain the identity information, or the vehicle-mounted camera may capture an image of a member in the vehicle, and the identity information of each member in the vehicle may be determined by combining with an identity query system (e.g., a public security population information query system), or the vehicle-mounted device may directly receive the identity information of the member in the vehicle, which is directly input by any user (e.g., a driver), or even may obtain the identity information by reading information in each identity card placed in the identification area by an identity card identification module provided on the vehicle-mounted device.
As identity information for describing personal information of each in-vehicle member, each in-vehicle member has unique identity information, and the age of each in-vehicle member is determined according to the obtained identity information in the application, so that the identity information at least has information which can be used for determining the age of the corresponding in-vehicle member, the information can be ready-made age information, and also can be the current age obtained by conversion based on the year, month and day of birth, and other information such as height, body type, weight, skull size and facial features cannot be used independently to obtain an accurate age, and can be matched and combined to determine the accurate age together.
S102: judging whether the children with the low ages exist or not according to the identity information, if so, executing S103, otherwise, not processing;
on the basis of S101, this step is intended to determine, by the vehicle-mounted device, whether a child of a low age is a generic term for a child whose age is lower than a preset age, where the preset age may be 4 years old based on a period of bone tissue weakness of the child, and the preset age may be adjusted to a corresponding age according to different regions and different races.
According to the difference of the specific identity information actually acquired in S101 for determining the age, the specific manner for determining whether a child with a low age is present in this step is also different. For example, when the current age of each in-vehicle member or the current age converted based on the birth year, month and day can be directly obtained in S101, it is of course possible to determine whether there is a child of a low age by comparing the sizes of the ages corresponding to the children of the low age; when the current ages of all the in-car members cannot be directly acquired (the children with low ages cannot have perfect registered identity information unlike adults), and only some information such as facial features, body types, body weights, skull sizes and the like can be acquired, whether the children with low ages exist or not can be determined by comparing the information with standard features extracted from corresponding categories of real children with low ages and based on a consistency conclusion expressed by the comparison result.
Further, it is considered that the information of facial features, body type, weight, skull size, etc. alone cannot determine the exact age, even an adult patient suffering from dwarfism or the like has the above-mentioned features similar to children and even children of a low age (if this is excluded, the individual can be used alone to determine the age).
S103: acquiring an actual seat of a low-age child in a vehicle;
this step is based on the determination result at S102 being that a young child is present, and is intended to acquire, by the in-vehicle apparatus, a seat in which the young child is actually seated in the vehicle (for convenience of subsequent citation and reference, hereinafter, the actual seating seat will be used collectively).
The vehicle-mounted equipment can acquire the information related to the actually seated seat in various ways, for example, images can be obtained by shooting the position of a young child through a camera in the vehicle, and the image characteristics related to the seat on which the young child sits can be determined through an image processing technology and taken as the information for determining the actually seated seat; when each seat in the vehicle is connected to a main control system in the vehicle, determining which seat the low-age child sits on according to information fed back by the seat corresponding to the position of the low-age child, and further determining the actually sitting seat; when each seat in the vehicle is provided with an information code (including a bar code, a two-dimensional code and a feature code) for indicating seat related information, the seat related information corresponding to the information code can be obtained through an information code identification technology, and the actual seat is determined according to the information code.
S104: judging whether the actual sitting seat is a child safety seat, if so, not processing, otherwise, executing S105;
on the basis of S103, this step is intended to determine whether the actual seat is a child safety seat by the in-vehicle apparatus. The child safety seat is a general term for all seats for ensuring the safety of children in a car.
The child safety seat for the automobile is also called a child Restraint system (crs), and is designed for children of different ages (or weights), is installed in the automobile, and can effectively improve the riding safety of the children. The definition of the child safety seat by the european regulation ECE R44/03 is: child safety system capable of being fixed to a motor vehicle, consisting of a safety belt assembly or flexible element with snap, an adjustment mechanism, accessories, etc. Can be combined with additional devices such as portable child beds, infant carriers, booster seats or crash shields. In the case of collision or sudden deceleration of the automobile, the impact force on the children is relieved, the body movement of the children is limited to reduce the injury to the children, and the riding safety of the children is ensured.
According to the difference between the specific information for determining the actual seating seat acquired in S103, the step also needs to adopt a corresponding manner to obtain the determination result of the step. For example, when the image block of the actual sitting seat separated based on the image processing technology is obtained in S103, the image block may be compared with the specific standard features of the child safety seat by image feature extraction and image recognition technologies in sequence, so as to determine whether the actual sitting seat is the child safety seat; when the feature code of the actual seat extracted from the information code is obtained in S103, the product type may be determined according to field information included in the feature code, such as the identification seat type, the manufacturer, and the satisfied seat safety production standard, so as to determine whether the actual seat is a child safety seat, and so on.
S105: and sending prompt information for changing the child safety seat.
This step is based on the determination result in S104 that the actual seating seat is not the child safety seat, and in order to ensure the riding safety of the younger child, the in-vehicle device sends a prompt message requesting the replacement of the child safety seat for the younger child. The prompt information can be sent to other members in the vehicle, or sent to the guardian of the younger child according to a preset address, and the prompt information can be embodied as short messages, mails, character or image information in various instant messaging applications, or can be a popup window or an audible/visual alarm, and the like, and is not particularly limited herein so as to realize prompt.
Further, the child in the low age is still a member in the vehicle, and before the child safety seat is not replaced, the vehicle is limited to normally run or enter a high-speed running state with the speed exceeding the preset speed. Furthermore, if the child safety seat is not replaced after being reminded for many times, the condition can be reported to a local vehicle management department or a traffic safety department through a preset path so as to force the child of the low age to replace the child safety seat.
Based on the technical scheme, whether a low-age child exists is determined according to the acquired identity information of the members in the vehicle, the actually-seated seat of the low-age child in the vehicle is further acquired under the condition that the low-age child exists, and finally, whether the actually-seated seat is a child safety seat is judged, so that a complete set of reminding mechanism for whether the low-age child uses the child safety seat is provided, the riding safety of the low-age child can be guaranteed as much as possible with the help of the reminding mechanism, and the injury phenomenon of the low-age child caused by non-professional vehicle interior protection measures can be obviously reduced.
In order to further understand the present solution, a specific embodiment is given herein for how to specifically achieve the purpose of the present application, taking an image processing technology as an example:
for S101, there is provided a specific implementation method for determining identity information of an adult in a vehicle through facial information as shown in fig. 2, which uses a facial image-based facial information acquisition technology, and includes the following steps:
s201: controlling a first in-vehicle camera to acquire the facial information of the in-vehicle member;
in order to collect the facial information of the members in the vehicle, which may be located at any position in the vehicle, the number of the first in-vehicle cameras may be multiple, and multiple first in-vehicle cameras may be specifically arranged in front of each in-vehicle seat, so as to shoot the facial images of the in-vehicle members sitting on the respective seats. Of course, the first in-vehicle camera may also be disposed in other places where the facial image can be captured, and is not limited in particular here.
Furthermore, in order to protect the privacy of the members in the vehicle and save the power consumption as much as possible, the method can also be realized by controlling the first vehicle camera to be opened only at a proper time, for example, only when the vehicle door is opened or closed or the engine is started, the vehicle-mounted equipment controls the first vehicle camera to start to collect the facial information. Specifically, the signals for obtaining the opening and closing of the door and the engine starting may be sent by sensors provided at the respective positions.
S202: determining the identity information of the members in the vehicle corresponding to the face information through a database;
wherein, the database prestores the corresponding relation between each face information and each identity information.
On the basis of S201, this step is intended to determine the identity information of each in-vehicle member by querying the database. The database can be specifically a national population information query database of a public security system, can be accessed by the vehicle-mounted equipment through a provided interface, and receives a query result.
Here, it is considered that the current age exists in the identity information stored in the database, and therefore, whether a member in the vehicle has a child of a low age can be determined by directly comparing the current age with the age corresponding to the child of a low age.
On the basis of confirming the existence of a child of a low age as a vehicle occupant, for S103, there is provided a specific implementation of acquiring an actual seating seat through an image separation technique as shown in fig. 3, including the following steps:
s301: controlling a second in-vehicle camera to shoot to obtain a riding state image of a child of a low age;
the second in-vehicle camera may be another in-vehicle camera different from the first in-vehicle camera, or may be the same in-vehicle camera as the first in-vehicle camera, as long as the same in-vehicle camera can not only achieve acquisition of facial information but also capture a riding state image.
The riding state image is centered on the young child, and information on the surroundings of the young child in the vehicle is included so that the riding state of the young child can be determined based on the information on the surroundings of the young child.
S302: and separating image blocks of the actual seating seats of the children in the vehicle from the seating state images by using an image separation technology.
In addition to S301, this step is intended to separate an image block of an actual seating seat of a child of a low age in the vehicle from the seating state image by an image separation technique by the in-vehicle apparatus. It will be appreciated that the seat is generally located beneath the occupant and is wrapped around the rear and sides of the occupant, so that based on this characteristic the image area of the corresponding location of the young child can be determined and separated into image patches that may be actual seating. Of course, the image blocks of the actual seating seat can also be separated in a targeted manner by using the generic image features of the seats in the vehicle.
Based on the scheme shown in fig. 3, with respect to S104, there is provided a specific implementation scheme for determining whether the actual seating seat is the child safety seat based on image similarity as shown in fig. 4, including the following steps:
s401: extracting actual image features from image blocks corresponding to actual sitting seats;
s402: judging whether the actual image features are consistent with the standard image features, if so, executing S403, otherwise, executing S404;
the two image features are not considered to have consistency only when the two image features are completely consistent, and according to different practical situations, if the two image features have more than a preset number of sub-features which are the same or two image features have more than a preset proportion of the same area, the two image features may also be considered to have consistency therebetween, which is not specifically limited herein.
S403: determining that the actual sitting seat is a child safety seat;
s404: it is determined that the actual seat is not the child safety seat.
Each of the above schemes is an implementation scheme given based on an image processing technology, and in order to make the final conclusion more accurate, the image shot by the camera may be preprocessed (for example, converted into a gray scale image, binarized, denoised, etc.), so that the part to be extracted in the image is clearer and the features are more obvious.
Fig. 2, fig. 3 and fig. 4 respectively show an implementation manner using an image processing technology as a specific implementation means for the key steps S101, S103 and S104 of the present solution, and it can be seen from the above that, besides the solution shown in fig. 4 needs to depend on the solution shown in fig. 3, there is no necessary dependency relationship between the solution shown in fig. 2 and the solution shown in fig. 3, and the solutions can be completely used alone to form the corresponding specific implementation solutions.
On the basis of any of the above embodiments, to determine whether a young child is actually seated in the child safety seat, a post-verification method based on the child safety seat may also be implemented, and one implementation manner, including but not limited to, as shown in fig. 5, includes the following steps:
s501: receiving weight information fed back by a weight sensor arranged on the child safety seat;
s502: and determining whether the child safety seat is in a state of being seated by a young child according to the magnitude of the weight information.
That is, the weight information fed back from the weight sensor is used to determine whether a load corresponding to a child of a low age is present on the child safety seat, thereby realizing confirmation. The weight of a child aged 0-4 years is usually 0-18 Kg, for reference.
Furthermore, in view of the nature of the child's mobility, it is likely that the child safety seat cannot provide effective safety guarantee due to the movement, and in order to solve this problem, an implementation scheme for determining the actual sitting posture based on the weight distribution information and issuing a reminder is provided as shown in fig. 6, and includes the following steps:
s601: receiving weight distribution information fed back by the weight sensor;
s602: determining the actual sitting posture of the young children according to the weight distribution information;
s603: and when the actual sitting posture is different from the standard sitting posture, sending a prompt message for please adjust the abnormal sitting posture.
The purpose of being capable of feeding back weight distribution information is achieved through the weight sensors arranged at the plurality of different positions on the child safety seat. The actual sitting posture of the young children on the child safety seat can be restored according to the weight distribution information, and when the actual sitting posture is different from the standard sitting posture, prompt information for please adjust the abnormal sitting posture is sent, so that the abnormal sitting posture can be corrected in time.
Because the situation is complicated and cannot be illustrated by a list, a person skilled in the art can realize that many examples exist according to the basic method principle provided by the application and the practical situation, and the protection scope of the application should be protected without enough inventive work.
