Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus type guide dog which can be used by a blind disabled person by purchasing the dog without waiting for a sequence of guide dogs, for a society. <P>SOLUTION: This guiding apparatus for a blind person mounts a battery and a charger on a hand truck in which electromagnetic brakes are mounted at right and left sides of rear wheels of a three-wheel or four-wheel vehicle, and carries a navigation for an ambulatory person, a gyro and an image collating recognition unit and a monitor television camera. The navigation for a pedestrian is a means for informing the pedestrian of his present position via a voice, transmitting a bearing (a latitude and a longitude) to the gyro, and providing a voice guide by an input of a destination. The gyro receives the bearing, commands a wheel brake operation and can automatically change and walk the direction of the hand truck. In the case of a down slope or the like, the gyro is a means for automatically moving the brake to hold a walking speed constantly. The recognition unit is a means for supplementing capability out of the navigation for the person. In view of a sudden obstacle, it is sensed by a sensor to produce a signal, and the direction is automatically corrected to avoid the obstacle. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be purchased by those who need a guide dog and are waiting for the guide dog.
It is a device-type guide dog robot that can be obtained without waiting for a turn, and an image collation recognition device that is a means to realize that robot.

[0002]

2. Description of the Related Art In order for blind persons to go out, it is necessary to rely on a caregiver or a guide dog.

[0003] Conventional guide dogs take a long time for training and many guide dogs cannot be raised.

Therefore, perfect dogs are few. In the case of dogs, they don't have to be fed, they have to be raised. For that reason, a caregiver is necessary.

There are 783 guide dogs in Japan, but there are 353,600 people who need guide dogs. These people are waiting for their turn.

Currently, research and development is being conducted on guidance guidance systems, talking roads, etc., but it is certainly possible if you enter the area as much as you can. But how do you get there? After all, a guide dog is necessary.

Guide dogs are dogs. It's an animal. Therefore, even if you want to enter, there are places where you cannot enter. It ’s a restaurant,
Hotels, supermarkets, etc.

SUMMARY OF THE INVENTION An object of the present invention is to provide a walker which a blind person can purchase by purchasing.

By using this walker, it is possible to provide society with a device-type guide dog according to the advantage that it can be freely inserted anywhere regardless of location.

In addition, it is possible to walk with a feeling similar to that of a healthy person by informing the blind person by voice.

[0011] It is to provide a visually impaired person with a robot that guides them only by pushing this wheelbarrow.

[0012]

In order to solve the above-mentioned problems, in claim 1, an electromagnetic brake is attached to each of the left and right rear wheels using a three-wheel or four-wheel walker as a base. This electromagnetic brake is a means to operate automatically and to control the automatic direction correction function and walking speed.

The pedestrian navigation informs the computer of the current position of the pedestrian by the azimuth (latitude, longitude),
Also, it is a means to instruct the route by inputting the destination.

The gyro is. It is a means to confirm the horizontal angle of the walker and to serve as a compass, output information to a computer, process the azimuth information from the above navigation and the gyro information by the computer and transmit them to the brake.

The gyro is a means for keeping a constant walking speed by notifying by voice in case of a downhill, transmitting a predicted increase in the speed of a walker to a computer, and operating a brake.

The front monitoring sensors are means for attaching to both ends of the walker, detecting an obstacle in the vehicle width, and automatically operating the brake.

For example, if the sensor on the right side is closed, the brake on the left side works and the vehicle body turns to the left until the block is released. On the contrary, if the left sensor is closed, the right brake works and the car body turns to the right until the block is released.

The operation from the computer to the brake is the same, and is a means for automatic direction correction.

The image collation recognition device according to claim 2 is a means for notifying an object in front by voice.

Therefore, the images that will come in during walking are stored in advance in the memory chip with images from various angles, and the images input from the monitor TV are collated with a computer to determine what the object is. Judge whether or not
This is a device that outputs audio.

Further, it is means for informing a computer of information of an unexpectedly incoming object and transmitting the operation to the brake so as to avoid the object and automatically correcting the direction.

Since the walking speed of the pedestrian is 4 km / h in the monitor TV, it is sufficient if the prediction can be made 5 seconds before assuming 1 m for 1 second. In other words, it is only necessary to be able to confirm up to 5 m ahead. There is a problem of luminosity, but if necessary, the light is also the means.

The check discrimination between the monitor television image and the memory image is a means for determining the percentage and freely selecting the setting of the percentage.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an apparatus type guide dog according to claim 1 as a first embodiment.

FIG. 1 is an overall conceptual diagram of the present invention, but this is one form, not a determinable form. This is because the shapes are different in design.

In FIG. 1, 1 is a monitor TV and 2
Is the installation location of the image memory device, pedestrian navigation, gyro, and computer, and 3 is the installation location of the battery and battery charger.

Reference numeral 4 in FIG. 1 is a handle held by a pedestrian, and is not determined in this figure. This is because blind people actually choose a cheaper form.

In FIG. 1, 5 is a front free wheel and 6 is a rear wheel with a brake, but this is not a decisive factor either.
In running, if the front wheels are the brake wheels and the rear wheels are the free wheels, the turning radius of the body can be small, but the pedestrian must move quickly. However, in the above case, the pedestrian's walking speed does not change, although the turning radius is large. This is because both the above cases and the cases described below have advantages and disadvantages.

FIG. 2 is a block diagram of a system implementation synthesis mode of the present invention.

A device for guiding the pedestrian by automatic piloting when the blind person with a disability wears earphones and pushes the walker of FIG. 1 on which the system device of FIG. It is a type of guide dog robot.

FIG. 3 is a configuration diagram of an embodiment system of the image collation recognition device of claim 2. That is, the instrument configuration is
An image of one object viewed from all angles up to a limited distance is stored in a memory chip, and the objects that can be seen while walking are recorded in the same manner as above.

Then, it is a device that instantly compares the images with the image input from the monitor TV and the computer, informs by voice what the object is, and sends a signal to the brake if the image suddenly enters.

In this image matching, perfect image matching is impossible. This is possible if we only match the images with the silhouettes. Also, the collation decision is determined by a percentage.

[0035]

[Effect of the Invention] The invention according to claim 1 is an integrated product of the present technology, which means that a blind person with a disability purchases it and contributes to a society where it can be used without waiting. Also, since the present invention is a device, it can be installed anywhere. It is a product that realizes a society in which blind persons can go out alone.

Further, claim 2 is a technical development necessary for the invention of claim 1 and is a means for playing the role of vision.
