Abstract

The invention discloses an automobile sensing system for recognizing passenger existence by images. The automobile sensing system for recognizing passenger existence by images comprises an imaging device, a face image recognition controller and a segmentation judgment controller; a camera picks up images; the face image recognition controller recognizes existence status of a passenger; and the segmentation judgment controller judges the position of the passenger, so that the function of automatically starting up a safety belt reminding device, a reading lamp in the automobile and a recreation apparatus and the like is realized; and the camera is small in size, easy to arrange and simple in logic control, and the requirement of judging the existence of the backseat passenger is met.

Description

There is sensory perceptual system in automobile with image identification occupant

Technical field

The present invention relates to the occupant safety field, be specifically related to automobile image and detect the identification field.

Background technology

Increase along with the safety belt reminding device requirement, rear row's personal harness has prompting function will obtain certain bonus point in EU-CANP, general occupant's sensory perceptual system achieves the goal by installation contact pressure sensitive original paper in the Chain cushion and realizes that safety strap is not the judgement whether prompting function is opened, this original paper places in the Chain cushion, for guaranteeing sensing range, generally be paved with cushion more than 2/3rds, easily produce fatigue failure, the faults such as wrong report under the long-term pressured state.

Summary of the invention

The present invention carries out the judgement that the occupant exists by impact, reaches the arbitration functions of automobile passenger sensory perceptual system, by cordless, has improved the problem that accuracy of detection has avoided the sensor contact measurement to lose efficacy after the long-term time.

There is sensory perceptual system in automobile with image identification occupant, comprising:

Obtain the camera of image;

Judge the Identification of Images controller of occupant's location;

Corresponding one by one with the quantity of seat and safety strap, control respectively the open position segmentation of the safety belt reminding device of diverse location and judge controller;

Described camera obtains video data and is input to the Identification of Images controller, and the Identification of Images controller is judged occupant's particular location according to human Facial Image Recognition Algorithm, then the occupant position signal is exported to location segment and judges controller;

Location segment is judged controller according to the occupant position signal that obtains, and the safety belt reminding device corresponding to the relevant position exported start signal.

The present invention judges to control safety belt reminding device by collection and Identification of Images to vision signal, has avoided traditional occupant to have the problem of pressure type induction original paper fatigue failure in the sensory perceptual system, and it reduces arrangement areas, does not limit occupant's sitting posture.

Description of drawings

Fig. 1 is fundamental diagram of the present invention.

The specific embodiment

Be described in detail of the present invention below in conjunction with drawings and Examples.

As shown in Figure 1, there is sensory perceptual system in automobile with image identification occupant, comprises the camera (1) that obtains image; Judge the Identification of Images controller (2) of occupant's location; Corresponding one by one with the quantity of seat and safety strap, control respectively the open position segmentation of the safety belt reminding device of diverse location and judge controller (3);

Described camera obtains video data and is input to the Identification of Images controller, and the Identification of Images controller is judged occupant's particular location according to human Facial Image Recognition Algorithm, then the occupant position signal is exported to location segment and judges controller;

Location segment is judged controller according to the occupant position signal that obtains, and left side safety belt reminding device (4) or the right side safety belt reminding device (5) corresponding to the relevant position are exported start signal.

Claims (1)

1. there is sensory perceptual system in automobile with image identification occupant, comprising:

Obtain the camera of image;

Judge the Identification of Images controller of occupant's location;

Corresponding one by one with the quantity of seat and safety strap, control respectively the open position segmentation of the safety belt reminding device of diverse location and judge controller;

Described camera obtains video data and is input to the Identification of Images controller, and the Identification of Images controller is judged occupant's particular location according to human Facial Image Recognition Algorithm, then the occupant position signal is exported to location segment and judges controller;

Location segment is judged controller according to the occupant position signal that obtains, and the safety belt reminding device corresponding to the relevant position exported start signal.
