Problems solved by technology

If the driver turns on the dome light inside the car, it will cause reflections on the window or front windshield, which will interfere with the driver's observation of the road outside the car.
The opening and closing of the ambient light in the car also requires the driver to operate a specific switch in the car, which is extremely inconvenient for the driver while driving, thus resulting in poor user experience.

Embodiment 1

[0064] figure 1 It is a flow chart of a method for controlling the switch of the ambient light in the car provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the ambient light in the car is turned on or off intelligently according to the driver's face orientation position. The method can be performed by A device for controlling the switch of the ambient light in the car is implemented, which specifically includes the following steps:

[0065] Step 110, when the ambient light control event is triggered, determine the driver's face orientation position, and determine the driver's interest area according to the face orientation position.

[0066] Wherein, the face orientation is the spatial angle of the driver's face orientation position in the set three-dimensional coordinate system. For example, the facial orientation may include the angle between the projection line of the driver's line of sight on the XY plane of the three-...

example 1

[0068] The corresponding relationship between the driver's face orientation and the area in the car where the ambient light is set is established in advance through the central processing unit. Example 1: When the central processing unit predetermines that the driver's face is facing the bridge and the area above the bridge, the angle between the projection line of the driver's line of sight on the XY plane and the Y axis in the above three-dimensional coordinate system, and the driver's face orientation For the area above the bridge and above the bridge, the angle between the driver's line of sight and the Z-axis in the above three-dimensional coordinate system. The establishment of the corresponding relationship between the driver's face orientation and other areas provided with ambient lights is the same as the above example, and will not be repeated here.

[0069] On the premise that the central processor triggers the ambient light control event, the driver's facial orient...

Embodiment 2

[0078] figure 2 It is a flow chart of the steps of determining the area of ​​interest of the driver in the method for controlling the switch of the interior ambient light in the second embodiment of the present invention. On the basis of the above-mentioned technical solution, the technical solution of this embodiment specifically introduces the steps of determining the driver's face orientation position and determining the driver's region of interest according to the facial orientation position, specifically including the following steps:

[0079] Step 210, determine facial feature data corresponding to the driver in the video image.

[0080] Wherein, the facial feature data includes head / face position coordinates or line of sight coordinates, etc. The central processing unit executes a video frame division operation on the acquired video image, so as to obtain each frame image included in the video image. The central processing unit extracts facial feature data included i...

Abstract

An embodiment of the invention discloses a method and a device for controlling on and off of atmosphere lamps in a car and belongs to the technical field of Internet of Vehicles. The method comprises steps as follows: when an atmosphere lamp control event is triggered, the facial direction position of a driver is determined, and a region-of-interest of the driver is determined according to the facial direction; whether actions of the driver corresponding to the region-of-interest meet a preset rule is judged, so that whether the atmosphere lamps corresponding to the region-of-interest are turned on is determined. With the adoption of the method and the device, the problem that the driver takes objects very difficultly when driving at night at present is solved, which atmosphere lamps are turned on is determined according to the facial direction position of the driver to provide lighting, the driver finds objects to be taken conveniently, the operation is more intelligent and convenient, and the driving attention of the driver is not diverted.

Description

technical field [0001] Embodiments of the present invention relate to Internet of Vehicles technology, and in particular, to a method and device for controlling a switch of an ambient light in a vehicle. Background technique [0002] With the development of society, cars have gradually entered life from a high-end means of transportation, and more and more people have their own cars. With the popularity of vehicles, people's requirements for cars gradually tend to be in the direction of safety and convenience. [0003] During the research process of the present invention, the inventor found that the driver is likely to face the following troubles when he is in the car (driving or parking) at night: The interior light is very dim, and it is very difficult to find the items to be picked up. If the driver lowers his head to rummage carefully, it may divert driving attention (under the situation of driving), which reduces the driver's risk response ability when driving. If th...
