Problems solved by technology

[0004] However, the above-mentioned prior art is effective for restraining human-made driving faults caused by dangerous driving behaviors such as squint driving and dozing driving of the driver, but it is not effective for the driver's inexperience, decreased attention, etc. Man-made driving negligence caused by the negligence of the safety confirmation behavior has no effect

no. 1 approach

[0031] (driver monitoring device)

[0032] First, refer to figure 1 as well as figure 2 A schematic configuration of the driver monitoring device 20 will be described.

[0033] figure 1 is a system configuration diagram showing a schematic configuration of the driver monitoring device 20, figure 2 It is a schematic diagram showing how the driver monitoring device 20 is mounted on the vehicle 10 .

[0034] The driver monitoring device 20 includes a driver monitoring camera 21 and a face recognition system 23 to constitute a driver monitoring system. The face recognition system 23 includes a detection unit 23a, a determination unit 23b, and a storage unit 23c.

[0035] The driver monitoring camera 21 is mounted on the vehicle 10 and captures the face of the driver 30 driving the vehicle 10 . The detection unit 23 a detects safety confirmation behavior information related to the safety confirmation behavior of the driver 30 based on the facial image of the driver 30 captu...

no. 2 approach

[0081] In the first embodiment, the driver monitoring device 20 according to the present embodiment is applied to the vehicle 10 , but it may also be applied to a moving object controlled by a person such as an flying object or a ship. Therefore, the term "driving" here is a concept that includes not only vehicles but also situations in which mobile objects such as flying objects and ships are manipulated. In this case, the driver is also referred to as the operator.

no. 3 approach

[0083] refer to figure 1 as well as Figure 8 A third embodiment of the present invention will be described.

[0084] Figure 8 It is a graph showing the change over time of the number of times of negligence of safety confirmation behavior during driving and the number of times of dangerous driving behavior. In addition, in Figure 8 In the graph shown, squint driving and dozing off driving are exemplified as dangerous driving behaviors.

[0085] Compared with the driver monitoring device 20 described in the first and second embodiments, the driver monitoring device 20 according to the third embodiment records the determination result in the storage device (specifically, the drive recorder 25( refer to figure 1 )] This is different. By setting in this way, the driver's own driving situation and safe driving technique confirmation can be performed.

[0086] The driver monitoring device 20 according to the third embodiment calculates the number of safe driving behaviors c...

Abstract

The invention provides a driver monitoring device which is provided with a driver monitoring camera that takes an image of a face of a driver; a detection unit that detects safety check action information related to a safety check action of the driver on the basis of a face image of the driver captured by the driver monitoring camera; and a determination unit that determines whether or not the driver is neglecting the safety check action on the basis of the safety check action information detected by the detection unit.

Description

technical field [0001] The present invention relates to a driver monitoring device for prompting a driver to perform a safety confirmation action when a mobile body such as a vehicle is running. Background technique [0002] For example, nearly 90% of traffic accidents are caused by human driving errors. Among them, as a major cause, it can be considered that the driver's dangerous driving behavior such as squinting driving, dozing off driving, etc., the driver's inexperience, and the lack of attention (not paying attention) are the negligence of the safety confirmation behavior. Conventionally, there is known a driver monitoring device, wherein, in order to reduce such man-made driving errors, in recent years, the driver's face is photographed by an on-board camera or other imaging device for the purpose of driver monitoring. The image detects facial information such as the direction of the driver's face and the degree of opening of the eyelids, and when it is determined t...
