Problems solved by technology

However, the camera on the screen is used to shield this part of the light and not restore the real scene, which will cause output errors after machine learning and affect the use effect; 3) It is not easy to collect side images (or large-angle images) of faces. It requires people to turn their head nearly 90 degrees. Firstly, the experience is not good. Secondly, the gaze point of the human eye needs to be far away from the side of the person, which will lead to a very long length of the device carrying the gaze point.
4) In the process of intelligent driving, due to technical limitations, such as the blind area of ​​the camera and the limited distance of the sensor, there are potential safety hazards

Embodiment 1

[0042] like figure 2 As shown, the intelligent driving system of the present invention includes four parts including a central control unit, a GNSS and wireless communication unit, an information collection unit, and an execution unit.

[0043] The central control unit may include: a central processing unit, a memory; and a manual driving mode, multiple automatic driving modes and a safety unit stored in the memory;

[0044] GNSS and wireless communication unit provide vehicles with global positioning systems, such as GPS, Beidou, etc., and can also provide vehicles with wireless network connection servers;

[0045] The information collection system includes multiple camera units, various sensors, and the vehicle’s own condition information collection unit; the multiple camera units include the acquisition unit of the scene outside the vehicle to provide support for intelligent driving, such as whether there are vehicle brakes ahead, whether there are traffic lights ahead, W...

Embodiment 2

[0050] The same steps and / or structures in this embodiment and the above embodiments are not repeated, and this embodiment only introduces some changes or more specific steps and / or structures.

[0051] The intelligent driving system of the present invention consists of four parts: a central control unit, a GNSS and wireless communication unit, an information collection unit, and an execution unit.

[0052] In this embodiment, it should be emphasized that the pre-trained classifier includes not only samples whose gaze coordinates of human eyes are located on the front windshield, but also samples of left, middle, and right rearview mirrors.

[0053] In the scenario of smart parking, the driver also needs to pay attention to the driving situation. In this mode, the safety unit collects the face image through the driver's eye monitoring camera unit (that is, the DMS image acquisition unit) and inputs the face image To the trained classifier unit, the classifier unit outputs the ...

Abstract

The invention relates to the field of automatic driving, in particular to an intelligent driving system for concerning the attention of a driver. The intelligent driving system comprises a central control unit, an information collection unit and the like. The central control unit further comprises a safety unit, and in the intelligent driving mode, the safety unit ensures the driving safety by detecting the coordinates of the position to which the human eyes pay attention in real time. In order to ensure the sight position detection accuracy, the images of the human face at various angles canbe efficiently collected by using a home-made data acquisition chassis for training; by using a neural network, a human eye image and a human head gesture image are fused together to be input into theneural network, so that the neural network learns the eye and head gesture overlapped image data, that is specially for a collected high-quality image data set for training, a neural network matchedwith the image data set is designed.

Description

technical field [0001] The invention relates to the field of intelligent driving, in particular to an intelligent driving system focusing on driver's attention. Background technique [0002] At present, in the prior art, various monitoring sensors and image acquisition devices installed at the driving position are mostly used to monitor the driver's attention in intelligent driving. like figure 1 As shown, the existing intelligent driving system includes image acquisition devices and various sensors; for example, detecting whether the driver holds his hand on the steering wheel for a long time, whether the steering wheel is turning, and whether the vehicle senses the driver's acceleration or braking. signal etc. These traditional sensing devices are too sensitive, causing the vehicle to overreact, although the driver is not inattentive at this time. In addition, although the sensor senses that the driver is controlling the steering wheel, the driver's attention is on othe...
