Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the object recognition and walking guide device for the visually impaired according to an embodiment of the present invention includes a mounting unit 1, a main body 2, and an operation unit 3.

The mounting portion 1 is in a band form, and can be attached to and detached from the head by a detachment means such as a Velcro, and includes a GPS 13 (Global Positioning System), an orientation measuring unit 12, an image photographing unit 14, a row The sensor 15 includes a proximity sensor 16, a proximity detector 16, a proximity photographing unit 17, a tactile display 11, a motion detector 19, and a first communication unit 18.

The GPS 13 acquires information on the location of the visually impaired person and transmits the obtained information to the main body 2 through the first communication unit 18. Detailed description thereof will be described later.

The azimuth measuring unit 12 includes approximately eight directions, that is, an electronic compass for detecting east, west, south, north, northeast, northwest, southeast, and southwest, and information on which direction the visually impaired person stands in. And obtain the obtained information to the main body 2 through the first communication unit 18. Detailed description thereof will be described later.

The image capturing unit 14 is a camera using a CMOS sensor of about 640 * 320 pixels, and the like. The image capturing unit 14 acquires image information by photographing the front of a visually impaired person. It transmits to the main body 2 via 18. FIG. Here, the image capturing unit 14 processes the image signal into RGB signals during the day, and processes them in grayscale using infrared (IR) at night and transmits them to the main body 2 through the first communication unit 18. do. This is difficult to obtain an image because the operation of the CMOS sensor is slow in the place where the light amount is small due to the characteristics of the camera. Therefore, during the day with a large amount of light, it is separated and processed into RGB signals, and at night with a relatively low amount of light, infrared rays (IR) are used to process the grayscale. Accordingly, the description thereof will be omitted since it is already known and widely known.

The thermal sensor unit 15 is used, such as an electronic thermal sensor, and the like to obtain information by sensing the heat of an object disposed in front, and to obtain the obtained information to the main body 2 through the first communication unit 18. send. This is used to distinguish a real person from a doll or a mannequin using only an image, that is, to distinguish between living things and non-living things, which will be described later.

The proximity detecting unit 16 uses an ultrasonic sensor, and obtains information confirming the presence or absence of an obstacle when a person or a vehicle approaches the visually handicapped person or the visually handicapped person approaches an obstacle, and obtains the acquired information. 1 is transmitted to the main body 2 through the communication unit 18 and outputs an alarm sound through the sound output unit 26. At this time, the sensing range of the proximity sensing unit 16 detects an obstacle within a total range of 120 ° within 70 cm in front of the inclination angle of 60 ° up to 60 ° from the bottom. If the visually impaired person perceives an obstacle that is 70 cm away from the visually impaired person, avoid it. Proximity detection unit 16 detects this obstacle to the, and outputs an alarm sound through the sound output unit 26 to inform the visually impaired.

The close-up photographing unit 17, a macro camera or the like is used, and is connected to the proximity detecting unit 16 to operate simultaneously with the obstacle is detected from the proximity detecting unit 16. In this case, the close-up photographing unit 17 has a focal length within 70 cm, captures obstacles to obtain a picture, and transmits the obtained picture to the main body 2 through the first communication unit 18. This is because it is difficult to avoid obstacles with only an alarm sound when a situation in which a visually impaired person needs to avoid obstacles occurs, so it is necessary to understand what obstacles are. However, in the case of an obstruction of a thin line, it may not appear well even when the image photographing unit 14 photographs. For example, in the case of the image capturing unit 14, since the focus range is set to infinity, it may not be recognized if a thin line is close. Therefore, a separate camera having a focal length for capturing small obstacles more precisely may be mounted so that the blind person can more clearly distinguish the obstacles and easily avoid the obstacles.

The tactile expression unit 11 is in close contact with the forehead of a visually impaired person, and receives an input of data to output an electrical signal for stimulating the tactile sense. In this case, the tactile display unit 11 is formed by distributing a rectangular shape in which approximately 512 points at which an electrical signal is output are distributed in a rectangular shape so that the shape of the object can be shaped. Or text is shaped so that the visually impaired person recognizes the object or the situation ahead. A description thereof will be described later.

The motion detection unit 19 switches the mounting unit 1 and the main body 2 to the power saving mode when there is no movement of the visually impaired in order to reduce the amount of electricity used. At this time, when the transfer to the month-saving mode, the mounting unit 1 operates only the operation detection unit 19, the proximity detection unit 16, the main body 2 operates only the second communication unit 21, the rest of the operation Will stop and go to standby. Accordingly, it is possible to go out for a long time by reducing the amount of electricity used. A description thereof will be described later.

The first communication unit 18 is obtained from the GPS 13, the orientation measuring unit 12, the image photographing unit 14, the thermal sensor unit 15, the proximity detecting unit 16, and the proximity photographing unit 17. Send a piece of information.

The second communication unit 21 receives the information transmitted from the first communication unit 18, and transmits the data processed by the main body 2 to the first communication unit 18. In this case, the first communication unit 18 and the second communication unit 21 may be connected by wireless or wired.

The third communication unit 25 is connected to a wireless communication network (not shown) and connected to a location information server provided through the wireless communication network. That is, the third communication unit 25 transmits the information obtained from the GPS 13 and the orientation measuring unit 12 to the location information server, and compares the data stored in the location information server to receive the surrounding information in real time. In addition, the information obtained from the image photographing unit 14 is compared with the data stored in the location information server to receive the information of the object in real time.

The memory unit 27 stores text message information, voice message information, and electronic map information for the visually impaired. For example, when a sudden obstacle appears in the front, voice message information such as "there is an obstacle" is stored, or the problem message information is stored so as to inform it through the tactile display unit 11. In addition, when the third communication unit 25 does not receive the information from the location information server, it executes the electronic map information, and by using the GPS 13 and the orientation measuring unit 12 in real time where the disabled person is now To text or voice.

The character input unit 23 is provided with a plurality of keypads for the braille, and the visually impaired person can input characters or retrieve data using the plurality of keypads. For example, in the case of a visually impaired person who is difficult to transmit by voice, communication to the other party is difficult. In this case, when a character is input through the character input unit 23, the character is output from the display unit 22, and the intention may be transmitted to the other party. In addition, the text output to the display unit 22 may be converted into a voice and output through the sound output unit 26. Accordingly, even a visually impaired person who is difficult to communicate by voice can communicate with the other party through the character input unit 23.

The display unit 22 is a place where the visually impaired character is displayed to the counterpart, and the character input from the character input unit 23 is output. Accordingly, the intention can be communicated to the other party by text. In this case, the sound output unit 26 may be notified to the visually impaired whether the message is properly written.

The sound output unit 26 outputs a warning sound when a sudden obstacle is detected from the proximity detecting unit 16 or a character input from the character input unit 23 as a voice. In addition, information received from the third communication unit 25 may be output as voice. In this case, an earphone terminal unit (not shown) that replaces the sound output unit 26 may be provided in one portion of the main body 2. Accordingly, the visually impaired person may know various information by voice through the sound output unit 26 or the earphone (not shown).

The central processing unit 24 is connected to the second communication unit 21, the third communication unit 25, the memory unit 27, and the sound output unit 26, and the second communication unit 21 and the third communication unit 25. Processes the information received from and the command input from the character input unit 23. For example, in the image information acquired by the image capturing unit 14 and the proximity capturing unit 17, the image information is processed to generate the data through the tactile display unit 11 so as to transmit the form of the object, and then the second data is generated. It transmits to the communication part 21. In addition, by combining the information obtained from the heat sensor unit 15 and the image information to distinguish the real and non-living, that is, human or mannequins and informs the visually impaired. Moreover, the command input via the operation part 3 may be processed. A description thereof will be described later.

The operation unit 3 includes a fourth communication unit 32 and a key input unit 31 in a substantially walking stick shape that a visually impaired person carries.

The fourth communication unit 32 transmits the command input via the key input unit 31 to the second communication unit 21.

Key input unit 31, "Help", "I am blind. I will pass." The voice or text that is simply requested to the other party is provided with a plurality of keys to output the command through the main body 2, and the input command is transmitted to the fourth communication unit 32. Accordingly, the visually impaired person may pass a doctor through the key input unit 31 by outputting a simple message.

Here, the body 2 may be carried by a visually impaired person in one hand, but may be worn on a part of the body to increase portability. In addition, the main body 2 may further include a microphone (not shown) in a portion of the main body 2 so that a visually impaired user may input a command by voice. In this case, the voice recognition is well known and publicly performed bar detailed description thereof will be omitted.

The first communication unit 18, the second communication unit 21, and the fourth communication unit 32 described above use near field communication, and use approximately RF, Bluetooth, and infrared rays, and the third communication unit 25 uses Wi-Fi (Wi). -Fi), 3G (3rd generation mobile communication), 2G (2nd generation mobile communication) and the like. In addition, the mounting portion 1, the main body 2 and the operation unit 3 is waterproof and can be used even in rainy weather.

On the other hand, the mounting unit 1, the main body 2 and the operation unit 3 is a portable device, the battery for supplying power to the skilled in the art will be obvious configuration, and the battery is known and widely practiced in the present invention the battery The description will be omitted.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the object recognition and gait guide device for the blind according to an embodiment of the present invention.

First, the wearing part 1 is worn so that the tactile expression 11 is closely attached to the forehead of the visually impaired head.

When the visually impaired person walks while wearing the mounting unit 1, the image photographing unit 14 captures an image of the front to obtain information, and acquires information on the position of the visually impaired person in the GPS 13, and the defense The measurement unit 12 acquires information on the direction of the visually impaired person. Then, the heat sensor 15 acquires information on the heat of the object, the proximity sensor 16 detects in real time whether an obstacle enters within 70 cm of the visually impaired, and the motion detector 19 Detect if the person with a disability is moving. At this time, when the visually impaired person is sitting or standing without moving, the motion detection unit 19 is considered that there is no activity of the visually impaired, and is switched to the power saving mode to the motion detection unit 19 and the proximity detection unit 16. Configurations other than the second communication unit 21 enters the standby state. Here, when an object appears within 70 cm in front of the visually impaired, the proximity detecting unit 16 detects it and takes a picture in the proximity photographing unit 17. The first communication unit 18 is activated while the proximity detecting unit 16 and the proximity photographing are taken. The information obtained by the unit 17 is transferred to the second communication unit 21 through the first communication unit 18. When the second communication unit 21 receives the information from the first communication unit 18, the standby state of the remaining components of the main body 2 is released, and the main body 2 processes the information received from the second communication unit 21 and the data. Create That is, the photograph generates data so as to know the specific shape through the tactile display 11 and transmits the data to the tactile display 11. At this time, the alarm sound in the sound output unit 26 may sound for 1 second to 2 seconds. Here, the alarm sound may be omitted from the sound output unit 26 and the alarm may be notified through the tactile display unit 11. This can be determined by the visually impaired setting method of the main body 2.

When the visually impaired person walks, the image photographing unit 14 acquires information by capturing an image, and the thermal sensor unit 15 obtains information by measuring heat of an object in front of the GPS 13 and azimuth. The measurement unit 12 acquires information about the position and the direction. The obtained information is transmitted to the second communication unit 21 through the first communication unit 18, and the information obtained by the image photographing unit 14 and the thermal sensor unit 15 is transferred to the image and heat unit in the central processing unit 24. Compare and compare the shape and the creatures and non-living objects to generate data, and the information obtained from the GPS 13 and the orientation measuring unit 12 is transmitted to the location information server through the third communication unit (25).

The data processed by the central processing unit 24 is transmitted to the first communication unit 18 via the second communication unit 21, and the data transmitted to the first communication unit 18 is transmitted to the tactile display unit 11 and transmitted. The data is expressed in the form or message of the thing in the tactile display unit 11 and transmitted to the visually impaired. Accordingly, the visually impaired person may distinguish between living and non-living objects through the tactile display unit 11 and determine the shape of the object. If there is no heat sensor 15, the visually impaired person should walk based only on the shape. In other words, when a blind person needs to ask for help, he may approach a mannequin or a doll and ask for help, especially if a person is obscured by an obstacle such as a door or safety sign. do. However, the present invention, by applying the heat sensor 15, it is possible to detect the body temperature over the obstacle even if a person is obstructed by the obstacle, it is easy to find the direction of people, in particular, the shape and the heat of the object In this way, you can reach out to real people and ask for help. Therefore, it is possible to prevent a blind person from approaching a mannequin or a doll and asking for help, and even people obscured by obstacles can easily detect people by detecting body temperature.

Meanwhile, the information transmitted to the location information server finds information that matches the information stored in the location information server and transfers the information to the third communication unit 25 through the communication network. Information received from the location information server informs the blind, such as the current location and buildings in front of the walking. In other words, it uses the function of augmented reality to tell in real time what is ahead. At this time, the image or barcode of the thing may be transmitted to the location information server, and information corresponding to the information may be transmitted to the main body 2 in real time to know the information of the thing.

The information received from the location information server is processed by the central processing unit 24 to generate data, and the generated data is notified to the visually impaired through the tactile display unit 11 or the sound output unit 26. At this time, the voice may be guided through the earphone plugged into the earphone terminal unit instead of the sound output unit 26 so as not to cause damage to the people around. As a result, the visually impaired person can know what building is several meters ahead. If the visually impaired person needs to enter the building, the navigation is terminated when the navigation is reached near the target point. At this time, the blind person should enter the target building but cannot know the direction of the target building. In other words, if there is a target building behind your back, you will not be able to find it, so you will have to help the people passing by. However, if you use augmented reality, you can see what building in front of the blind because it tells the local information ahead. Therefore, if the target building does not appear in front of the visually impaired person can turn the head or rotate the body to search the surroundings, even if the target point behind the back can be known exactly using the augmented reality. Accordingly, by accessing the location information server to obtain information, the visually impaired person can accurately find a desired target point. In addition, by acquiring information about a product using augmented reality, the visually impaired person may recognize what the product is.

Here, when a problem occurs in the third communication unit 25, the communication network or the location information server and cannot receive information from the location information server, the central processing unit 24 executes the electronic map stored in the memory unit 27. When the electronic map is executed, the GPS 13 and the azimuth measuring unit 12 may be used to acquire the direction of the visually impaired person and the area information ahead. Therefore, even if a problem occurs in the third communication unit 25, the communication network or the location information server, the visually impaired person can accurately find the desired target point.

On the other hand, the visually impaired person may input a command through the text input unit 23 to receive a guide to the target point or output a message requesting help through the display unit 22 or the sound output unit 26.

At this time, although the help may be requested through the character input unit 23, a simple help request or a request message for going the way may also be output through the key input unit 31 of the operation unit 3. Accordingly, when a visually impaired person is walking along the road and a person is detected by the manipulation unit 3, that is, a walking stick, the visually impaired person may be output to the person in front by pressing the key input unit 31 of the manipulation unit 3.

In describing the present invention described above, even if the embodiment is different, the same reference numerals are used for the same configuration, and the description may be omitted as necessary.
