The utility model discloses an eyeball technique of tracking can realize that the user is the controllable effect with eyes only on the wheelchair platform. And the cost is cheap relatively, and most family can all bear, and this technique is suitable for to be used widely.
Description
Technical field
This utility model relates to a kind of wheelchair that can control, and particularly relates to a kind of wheelchair utilizing eyeball tracking to control.
Background technology
Existing wheelchair is divided into two classes substantially, and one is common manual wheelchair, needs user with the hands to promote wheel turns and advances.Two is electric wheelchairs, and its principle on original manual wheelchair, installs two motor driving wheel additional rotate, and control mode is then generally at right hand side installing remote bar to control the direct of travel of wheelchair.But this control mode effectively can not manipulate wheelchair for losing both hands or the injured personage that cannot use of hand.And the existing Special wheel chair for these people is expensive, average family financial insolvency.
Eyeball tracking technology is a science application technology, when the eyes of people are seen to different directions, eye has trickle change, these changes can produce the feature that can extract, computer can extract these features by picture catching or scanning, thus the change of real-time tracing eyes, the state of prediction user and demand, and respond, reach the object with eyes control appliance.
And eyeball tracking technology is applied in used on wheelchair to control wheelchair and advances, design a kind of wheelchair utilizing eyeball tracking to control, and then make the people of normal operating wheelchair cannot to be convenient to manipulation, become technical problem urgently to be resolved hurrily at present.
Utility model content
The purpose of this utility model is to provide a kind of wheelchair utilizing eyeball tracking to control, and this wheelchair solves problems of the prior art.By eyeball tracking technology, the motion track detecting eyeball when wheelchair is advanced controls the left and right turn of wheelchair, and this technology is suitable for promoting the use of.
The purpose of this utility model is realized by following technical proposals.
A kind of wheelchair utilizing eyeball tracking to control, comprise wheel seat base, and be located at wheel seat base on wheelchair main body and wheel seat base below driving wheel and universal wheel, described wheelchair main body is provided with the display screen and eyeball tracking navigation system that are supported by support, wheelchair main body is provided with the main controller be connected with eyeball tracking navigation system with display screen, and main controller connects driving wheel.
Preferably, described driving wheel is provided with a pair, and be positioned at wheel seat base rear, universal wheel is provided with one, is positioned at wheel seat base lower front.
Preferably, described wheelchair main body comprises seat support and backrest, is provided with telescopic lifting bar below seat support, for regulating the height of display screen parallel with being sitting in human body sight line in wheelchair main body.
Preferably, described eyeball tracking navigation system comprises infrared camera for catching the corresponding position of eyeball and infrared sensor, and infrared camera is connected with controller with display screen respectively with infrared sensor.
Compared with prior art, the beneficial effects of the utility model are:
This utility model controls wheelchair as an eyeball tracking visual focus, can be applicable to Medical nursing field.Traditional wheelchair needs user both hands to operate, and do not have effect for gradually freezing the disabled that the both hands such as disease all cannot use, traditional control mode of control stick that utilizes creates significant limitation.This utility model can realize user on wheelchair platform only by eyes and controllable effect.And relative inexpensiveness, most of family can bear.Even if also can repacking be completed on common wheelchair.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further.
As shown in Figure 1 and Figure 2, this wheelchair utilizing eyeball tracking to control, comprise wheel seat base 3, and the wheelchair main body 7 be located on wheel seat base 3, driving wheel 6 and universal wheel 5 is provided with below wheel seat base 3, described wheelchair main body 7 is provided with the display screen 1 and eyeball tracking navigation system that are supported by support 4, and wheelchair main body 7 is provided with the main controller 2 be connected with eyeball tracking navigation system with display screen 1, and main controller 2 connects driving wheel 6.Driving wheel 6 is provided with a pair, and be positioned at wheel seat base 3 rear, universal wheel 5 is provided with one, is positioned at wheel seat base 3 lower front.
As shown in Figure 3, wheelchair main body 7 comprises seat support and backrest, is provided with telescopic lifting bar 9 below seat support, for regulating the height of display screen 1 parallel with being sitting in human body sight line in wheelchair main body 7.Eyeball tracking navigation system comprises infrared camera 8 for catching the corresponding position of eyeball and infrared sensor, and infrared camera is connected with controller with display screen respectively with infrared sensor.
This device seat is arranged on wheel seat base 3, and user is sat on the seat, by telescopic lifting bar 9 adjusting sitting posture.Then stare screen 1, correct shown in composition graphs 2.Stare corresponding position in figure according to calibration result to control advancing of wheelchair.Overall structure as shown in Figure 4.
As shown in Figure 5, nine points that user is stared in display screen are calibrated, and the intermediate point 11 at calibration retracement line focus place can redden.Extracted by the coordinate of these nine points and analyze, generate a set of coordinate system, screen upper left angle point 10 is (0,0), and screen bottom right angle point 12 is the ultimate resolution (1366,768) of current screen.Be advancement commands when region above user stares screen, below is for retreating, left for turning left, right for turning right.When even blinking twice or can't detect eyeball, wheelchair halts.
Operation principle of the present utility model is as follows:
With eyeball tracking navigation system can allow user pass through to stare the different position of screen reach controlling party to object.Eyeball tracking navigation system captures the corresponding position of eyeball by infrared camera, be at 0 with the mid point of two pupil center's lines and set up cartesian coordinate system, obtain the coordinate figure of two pupil positions, constantly export the coordinate figure of pupil position to control system, control system is used algorithm process to the signal of collection and is converted into control instruction, and instruction is conveyed to control system.Such as, user stares screen centre position, then wheelchair keeps moving ahead, if stare the left side or the right side of screen, then wheelchair turns to corresponding position.
Wherein eyeball capture system uses brand-new sensor to combine with infrared illumination system (photographic head), according to new track algorithm.High-resolution sensor, guarantees that we can follow the tracks of small action, maintains high-precision orientation range simultaneously.And optimize most of environment and illumination condition.Only need carry out calibration to screen before use to arrange, can use with the distance and slewing area of determining user and photographic head.
We are provided with blink detection in addition, carry out manual control according to information nictation to forward-reverse.Such as advance when user blinks at the moment to switch for twice continuously or retreat instruction.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that detailed description of the invention of the present utility model is only limitted to this, for this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to this utility model and be determined by submitted to claims.Scope of patent protection.
