Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, a main flow chart of an embodiment of an in-vehicle device regulation and control method based on occupant shape measurement according to the present invention is shown; in this embodiment, the method for regulating and controlling the in-vehicle device based on the occupant shape measurement includes the following steps:

step S101 is to identify persons existing in the surrounding environment, determine a travel route of each person, and determine the person as a passenger if the travel route is directed toward the vehicle.
It is understood that in the present invention, the range radar is a laser radar or a millimeter wave radar, etc., in the following examples, a laser radar is used as an example for description, the laser radar has functions of transmitting, scanning, receiving and data processing, for example, in some examples, the scanning frame rate of the laser radar used may be above 10 Hz; as shown in FIG. 2, the distance measuring radar is installed in the front, back, left and right methods of the vehicle, the full coverage of the vehicle body in the 360-degree direction in FIG. 3 can be realized, and the detection can be carried out within the radius range of 20 meters, for example.
Step S11, obtaining the shape information of each passenger through a vehicle-mounted distance measuring radar, wherein the shape information at least comprises height and fat information;
wherein the step S11 further comprises:
step S110, when the person walks, the person generally walks vertically, and the height measured at this time is more accurate. The ranging radar is used for shooting a plurality of ranging points on the body of a passenger through a scanning system, and the distance and the corresponding angle between each point and the ranging radar are measured through a Time of flight (TOF) method;
and S111, selecting the distance and the corresponding angle data of part of points, and combining a deep learning algorithm and neural network image recognition to calculate and obtain the height, the transverse width, the trunk size information and the action form of the person to be acquired.
As shown in fig. 4 and 5, in one example, the height of a person is calculated according to the cosine law by selecting a point b on the head of the passenger and a point a on the foot of the passenger, and calculating the distance lb and la and the included angle α: h = l a 2 +l b 2 -2×l a ×l b X cosa. Similarly, the lateral width w of the occupant can be calculated by the range radar hitting the lateral laser point of the occupant.
Wherein, in the step S111, the method further comprises:

if the head of the passenger is detected to be shielded (such as a hat, an umbrella and the like), height information from the part below the head to the sole of the foot is identified, and then height conversion is carried out according to the head height ratio to obtain the height information of the passenger.
In one example, the height value may be calculated using the following formula:
head-to-body ratio = height/full head height = height/(height-height below head), wherein asian people have a head-to-body ratio of 7 and european people have a head-to-body ratio of about 7.5.

the seat matching unit is used for determining the predicted seat position of each passenger according to the motion track of each passenger;
the regulating and controlling parameter acquiring unit is used for acquiring regulating and controlling parameters of equipment to be regulated and controlled related to the corresponding seat position according to the shape information of each passenger;
and the adjusting unit is used for adjusting each device to be regulated according to the regulating parameters.
9. The system of claim 8, wherein the scan processing unit further comprises:
the scanning activation unit is used for activating the range radar to start scanning the surrounding environment within the preset range when judging that the scanning starting condition is met; the scanning starting conditions are as follows: a remote control key of the vehicle enters a preset range, or the vehicle is started and is in a static state;
passenger confirmation for identifying persons existing in the surrounding environment, judging a traveling path of each person, and determining the person as a passenger if the traveling path of the person is directed toward the vehicle;
the recognition processing unit further includes:
the measuring unit is used for enabling the ranging radar to hit a plurality of ranging points on the body of the passenger through the scanning system, and measuring the distance between each point and the ranging radar and the corresponding angle through a flight time method;
and the recognition calculation unit is used for selecting the distance of part of points and corresponding angle data, and calculating and obtaining the height, the transverse width, the trunk size information and the action form of the person to be acquired by combining a deep learning algorithm and neural network image recognition.
10. The system of claim 9, wherein the seat matching unit determines the seat position of each passenger using the following method:
the seat position of each occupant in the vehicle is determined based on the specific vehicle door position to which the occupant has approached, in combination with the most recent occupant information when the vehicle door is closed.
11. The system according to any one of claims 8 to 9, wherein in the regulation parameter acquisition unit, the device to be regulated comprises at least one of a steering wheel, an air conditioner outlet, a seat, and an entertainment device;
the regulation and control parameters comprise at least one of the height of a steering wheel, the air outlet angle and the air outlet volume of an air conditioner, the front and rear positions of a seat, the height and the inclination angle of the seat and the height of a screen of the entertainment device.
