Problems solved by technology

[0003] However, the driver may experience driving fatigue after long-term driving, and cannot detect pedestrians threatening driving safety in time
On the other hand, in a complex traffic environment where there are too many pedestrians and the driving state is ever-changing, the driver can only pay attention to the pedestrians in front, and cannot observe the pedestrians on the side or even the rear in time.
[0004] Therefore, in the prior art, relying solely on the driver to manually judge the driving state of pedestrians and adopt a corresponding driving strategy will cause omissions and cannot fully guide the driver to drive, and may cause various safety accidents in severe cases

Embodiment 1

[0076] The following will combine figure 1 The driving assistance method shown in the exemplary embodiment of the present invention is introduced in detail.

[0077] see figure 1 , which is a flowchart of a driving assistance method provided by an embodiment of the present invention.

[0078] The assisted driving method provided in this embodiment specifically includes the following steps:

[0079] S101: Acquire an image sequence of the surrounding environment of the vehicle.

[0080] The image sequence can be obtained by taking a video of the vehicle's surroundings. When shooting, you can set the shooting range in advance. Generally, you can set the predetermined width and distance in front of the vehicle. For example, you can shoot a video image within 5 meters in front of the vehicle and within 20 meters in front. The shooting range can be set to different range sizes for different types of vehicles to adapt to different vehicle structures, so as to obtain ideal video i...

Embodiment 2

[0108] see figure 2 , which is a flow chart of another driving assistance method provided by an embodiment of the present invention.

[0109] The assisted driving method provided in this embodiment includes the following steps:

[0110] S201 in this embodiment is the same as S101 in Embodiment 1, and will not be repeated here.

[0111] S202: Determine pedestrian positions from the image sequence.

[0112] S203: Determine behavior attributes from the image sequence, S203 may specifically include the following S203a-S203c;

[0113] S203a: Obtain the size of the pixels occupied by pedestrians from the image sequence.

[0114] Adults are generally taller than minors. Therefore, when the pedestrian positions of adults and minors are the same, the size of pixels occupied by adults in the image sequence is larger than the size of pixels occupied by minors in the image sequence. For example, both adults and minors are 10 meters away from the vehicle, and the pixels occupied by a...

Embodiment 3

[0184] see Figure 4 , which is a structural diagram of a driving assistance device provided by an embodiment of the present invention.

[0185] The auxiliary driving device provided in this embodiment includes:

[0186] Image sequence acquisition unit 401 , pedestrian position determination unit 402 , pedestrian attribute determination unit 403 , pedestrian motion trend prediction unit 404 , pedestrian behavior prediction unit 405 , prediction unit 406 and warning unit 407 .

[0187] An image sequence acquiring unit 401, configured to acquire an image sequence of the surrounding environment of the vehicle.

[0188] A pedestrian position determining unit 402, configured to determine the position of pedestrians in the image sequence.

[0189] The pedestrian attribute determination unit 403 is configured to determine pedestrian attributes in the image sequence; the pedestrian attributes are used to characterize pedestrian categories.

[0190] The pedestrian motion trend predi...

Abstract

The invention discloses an assisted driving method and device, a vehicle-mounted terminal and vehicle. The method comprising: a step of acquiring an image sequence of a surrounding environment of thevehicle; a step of determining a pedestrian position and a pedestrian attribute in the image sequence, wherein the pedestrian attribute is used to represent a pedestrian category; a step of predictinga pedestrian movement trend and pedestrian behavior from the image sequence; a step of predicting pedestrian intent based on the pedestrian movement trend and the pedestrian behavior; a step of adopting a corresponding warning strategy based on the pedestrian location, the pedestrian attribute, and the pedestrian intent. The method can be used for automatically acquiring the image sequence of thesurrounding environment of the vehicle; the pedestrian position, the pedestrian attribute, the pedestrian movement trend and the pedestrian behavior can be obtained according to the image sequence; the pedestrian intent can be predicted according to the pedestrian movement trend and pedestrian behavior; finally the corresponding warning strategy is automatically adopted based on the pedestrian location, the pedestrian attribute, and the pedestrian intent to provide helpful assistance for the driver to drive safely, vehicle driving safety can be improved, and occurrence of traffic accidents can be reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a driving assistance method, device, vehicle-mounted terminal and vehicle. Background technique [0002] With the progress of the economy and society, the rapid development of the automobile industry, traffic safety has become a worldwide problem. At present, the recognition of the surrounding environment of the vehicle mainly depends on the driver, who manually observes the conditions of pedestrians around the vehicle to adopt corresponding driving strategies. [0003] However, drivers may experience driving fatigue after long-term driving, and cannot detect pedestrians that threaten driving safety in time. On the other hand, in a complex traffic environment, where there are too many pedestrians and the driving conditions are ever-changing, the driver can only pay attention to the pedestrians in front, and cannot observe the pedestrians on the side or even t...
