The experience of the same driving environment can be obtained when the same user drives different automobiles.
The invention can flexibly meet the requirement of the user on automatic adjustment of the driving environment of the shared vehicle according to the sitting habit of the user.
FIG. 3 is a partial flowchart of a driving environment adjustment method based on sitting posture habits according to an embodiment of the invention. As shown in fig. 3, each user ID may be associated with at least one set of first characteristic information, and each set of first characteristic information may correspond to at least one driving scenario. The step S200 includes:
s210, determining a current driving scene;
specifically, the determining the current driving scene includes one or more of the following steps S211 to S214:
and S211, determining whether the rear row of the target seat is occupied. Accordingly, the driving scene may be divided into two cases, i.e., a case where the rear row of the target seat is occupied and a case where the rear row of the target seat is unoccupied.
S212, determining the current time period. Accordingly, the driving scene can be divided into two cases, i.e., daytime and nighttime.
And S213, determining the current road condition. Accordingly, the driving scenario may be divided into: the current road is congested, the current road is smooth, the current road is flat, the current road is a mountain road and the like.
And S214, determining the current weather condition. Accordingly, the driving scenario may be divided into: the current weather is clear, the current haze concentration is higher than a preset value, the current weather is heavy rain and the like.
The driving scenes may exist individually or in combination.
S220, first characteristic information representing sitting habits of the user in the current driving scene is obtained from the cloud based on the user ID. The cloud end stores multiple groups of first characteristic information corresponding to the user ID, a driving scene is used as a set, and the multiple sets respectively comprise one group of first characteristic information; each set of first characteristic information may also be simultaneously classified into a plurality of sets (driving scenes).
The invention can flexibly meet the requirement of the user on automatic adjustment of the driving environment of the shared vehicle according to the sitting habit of the user. The state parameters of the seat do not need to be set mechanically according to the height and the weight of the user. In addition, the related data of personal preference such as the air conditioner temperature and the volume of the vehicle-mounted sound equipment which are frequently set by the user can be stored to the cloud end for the user to reserve. The experience of the same driving environment can be obtained when the same user drives different automobiles.
FIG. 4 is a flow chart of a driving environment adjustment method based on sitting posture habits according to another embodiment of the invention. Fig. 7 is an application effect diagram of the sitting habit based driving environment adjusting method of the invention. As shown in fig. 4, after step S600, the method further includes:
s700, acquiring second characteristic information representing the current sitting posture of the user; specifically, as shown in fig. 5, the obtaining of the second feature information representing the current sitting posture of the user may include:
s710, acquiring images of a plurality of angles of the current sitting posture of a user through a plurality of cameras; a plurality of cameras are arranged in the vehicle to acquire images with user sitting postures from multiple angles, and the accuracy of characteristic information extraction can be improved. As can be seen from fig. 7, the second characteristic information includes the height, body type, angle between the arm and the trunk, angle γ between the trunk and the thigh, angle β between the thigh and the calf, and angle α between the calf and the foot of the user. In addition, the angle θ between the head and the arm, the angle η between the arm and the steering wheel, and the like may be further included.
S720, extracting the second characteristic information from the images of the plurality of angles based on a Harris corner algorithm. In this embodiment, by using a Harris corner algorithm, an image edge feature and a gray feature are fused by using a method of fitting and weighting a weighted plane approximate gray surface and a principal curvature amplitude value of a related pixel, so that the accuracy of corner detection can be improved, and the error rate of angle calculation can be reduced. The invention does not limit the technical means adopted by image processing, as long as the second characteristic information representing the current sitting posture of the user can be extracted. It should be noted that, in this embodiment, after data representing the current sitting posture of the user is initially extracted, the data generally needs to be cleaned, data that significantly exceeds a reasonable range is removed, and then an average value of remaining data is taken as the second feature information as needed. The acquisition method of the first characteristic information can be consistent with the acquisition mode of the second characteristic information (the specific implementation mode can refer to paper number 1000-3428 (2013) 12-0167-04, and the website address: https:// wenku.baidu.com/view/4 eefd27088486262605. html).
It should be noted that, based on the development of the current image processing technology, the single measurement time is extremely short, and the duration of the whole recording process can be effectively controlled. FIG. 8 is a flow chart illustrating adjustment of a seat state parameter according to an embodiment of the present invention. As shown in fig. 8, wherein the angles of the at least three target nodes may include α, β, γ, η, θ shown in fig. 7. The folding angle can be adjusted to be higher or lower for the whole seat posture in a slight angle increasing or decreasing mode. The cleaning of the data may specifically include: and (4) carrying out six times of measurement, screening out the data with the deviation of more than 20 percent, reserving numerical values within a reasonable range, and then calculating and taking an average value.
S800, storing the second characteristic information to a cloud end to update the first characteristic information.
Specifically, the second characteristic information in the current driving scene can be stored in a cloud database and classified into corresponding sets according to the requirements of the user. And if the first characteristic information exists in the set, replacing the first characteristic information with the second characteristic information. Therefore, the driving habits of the user can be updated in real time, and the requirement of the user on automatic adjustment of the driving environment during riding is met.
In addition, if the corresponding first characteristic information cannot be acquired from the cloud based on the user ID, the first characteristic information of the user close to the user body type can be called as required and recommended to the current user, so that the driving environment can be adjusted correspondingly. For the occasions without cameras and other equipment around the seat, the seat state parameters matched with the characteristic information can be directly stored in a cloud or a mobile storage device and used as a direct basis for adjusting the seat state parameters. Need not to start the camera this moment, can directly snatch the anticipated state parameter of the seat of individual high in the clouds storage, carry out automatically regulated in view of the above. Thereafter, manual adjustment is again possible. After the manual adjustment is completed, the adjustment of the state parameters of the seat can be selected to be one-time operation or needs to be synchronized to a cloud end or a local storage device. The method can adjust at least one seat in a vehicle by one key for all seats in a vehicle, such as renting a shared car. Therefore, the requirement of the user for automatically adjusting the driving environment when riding the car can be met.
In addition, for public transport vehicles such as trains and airplanes which support seat selection and ticket purchase, the ticket selling platform can store seat state parameters commonly used by users in the ticket selling platform. After the passenger buys the ticket, the ticket buying platform sends the seat state parameters commonly used by the passenger to the corresponding seat so as to automatically adjust the seat state, and the passenger does not need to manually adjust the seat state after getting on the vehicle. If the manual adjustment of the seat state occurs, the seat adjustment parameters of the ticketing platform can be updated accordingly. Therefore, the requirement of the user for automatically adjusting the driving environment when riding the car can be met. The experience of the same driving environment can be obtained when the same user drives different automobiles.
Example 2
FIG. 6 is a flow chart of a driving environment adjustment method based on sitting posture habits according to another embodiment of the invention. As can be seen from comparing steps S100-S800 in fig. 4 with steps S10-S70 in fig. 6, the present embodiment is different from embodiment 1 mainly in that the first feature information is stored in a mobile storage device such as an NFC card, and the mobile storage device can be carried around. Therefore, the shared automobile can communicate with the mobile storage device in a wired or wireless mode to acquire the first characteristic information representing the sitting habit of the user from the mobile storage device. Further, after second characteristic information representing the current sitting posture of the user is obtained, the second characteristic information can be saved to the mobile storage device to update the first characteristic information. Therefore, the driving habit of the user can be updated in real time, and the requirement of the user on automatic adjustment of the driving environment during riding is met.
