Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. Shapes and sizes of the elements in the drawings may be exaggerated for clarity, elements denoted by the same reference numerals in the drawings are the same elements.

In the specification, when a part is "connected" to another part, this includes not only a "directly connected" but also a "electrically connected" between other elements in between. In addition, when a part is said to "include" or "include" a certain component, it means that it may further include or have other components, without excluding other components, unless specifically stated otherwise. .

Hereinafter, a first embodiment of a snow goggle having an augmented reality function according to the present invention will be described in detail with reference to FIGS. 1 to 2.

As shown in Figure 1 and 2, the snow goggles in the present embodiment is a mobile communication terminal 10, a transparent display 100 and a transparent display 100, such as a smart phone, tablet PC, smart watch, etc. It includes a main body 90 having a processor 80 that can control the augmented reality content to be projected. The processor 80 includes a memory for storing an augmented reality content program and information data, and controls an augmented reality image to be projected onto the transparent display 100. A mode selection button 70 is provided for selecting an augmented reality content to be projected onto the transparent display 100.

The mobile communication terminal 10 and the main body 90 are equipped with a Bluetooth and a Wi-Fi communication function to exchange data with each other, and the main body 90 is provided with a Bluetooth antenna 20 and a Wi-Fi antenna 30. These antennas are connected to the processor 80 so that the processor 80 controls the transmission and reception of data and processes the data.

The main body 90 may include a GPS receiver 40 to specify the position of the main body 90. The GPS receiver 40 is connected to the processor 80, and the processor 80 may display the position of the main body 90 as an augmented reality icon on the transparent display 100.

In addition, the main body 90 may include a camera 50 to capture an image or a video of an external landscape from the wearer's eyes. Such photographing data may be reproduced later through communication with the mobile communication terminal 10.

In addition, the main body 90 has a sensor 60 for measuring the surrounding state information and information for specifying the three-dimensional image of the augmented reality image, in the present embodiment, the left sound sensor 61 and the right sound sensor ( 62), an acceleration sensor 63, a temperature sensor 64 and a pressure sensor 65.

The pressure sensor 65 measures air pressure and measures altitude. The pressure sensor 65 receives air pressure information of a specific region through the GPS receiver 40 of the main body 90 through the mobile communication terminal 10 through the Internet network. Afterwards, the altitude is measured by using the measured air pressure and the received air pressure information. As in the conventional barometer, the altitude is 0 at 1 ATM, and the altitude may be calculated using the difference between 1 ATM and the measured air pressure. However, in this embodiment, since the altitude can be communicated with the mobile communication terminal 10, Internet information is More accurate altitude can be measured. That is, since the altitude of the station is specified, the atmospheric pressure information of the region can be converted to atmospheric pressure at the sea level of the region, and the current altitude is calculated by the following equation using the actual pressure measured by the pressure sensor 65. It may be displayed on the transparent display 100.

Since snow goggles are for outdoor activities at low temperatures, it is desirable for the user to check temperature information. Therefore, the temperature around the wearer can be measured by the temperature sensor 64 and displayed on the transparent display 100.

Since the current position may be specified through the GPS receiver 40, the current position may be displayed on the transparent display 100.

In addition, when a call is received from the mobile communication terminal 10 or a text message or an email is received, since the communication is possible with the mobile communication terminal 10 by using the Bluetooth antenna 20, a transparent signal is received in the currency exchange signal. Status, an incoming message and the like can be displayed.

In this embodiment, the above-described information on the altitude, temperature, current location and call reception are displayed as augmented reality images on the transparent display 100 as basic information.

3 to 7 illustrate a process of predicting and displaying a progress path of a user and a process of predicting and displaying a possibility of collision using a snow goggle system according to the present invention.

3 to 5, the gaze of the skier or snowboarder is related to the movement of the ski or snowboard, and the rotation of the body 90 is related to the gaze of the user. The acceleration sensor 63 may measure the acceleration and the angular acceleration of the main body 90 to detect the movement and rotation of the main body 90, and the user's moving speed V may be measured through the GPS 40 receiver. . If there is no acceleration applied to the main body 90 or if the acceleration is in a linear direction, the user proceeds with a straight path (see FIG. 4 (a)). In this case, the speed and the predicted linear path P1 are displayed as augmented reality on the transparent display 100 (S10, see FIG. 5). The direction of the straight path P1 is the same as the extension line of the locus received through the GPS receiver 40.

Referring to FIGS. 3, 4, 6, and 7, when the angular acceleration α of the main body 90 rotates instead of 0, the rotation path of the main body θ is measured, and then the user's progress path is predicted. . When the angular acceleration ( α ) is measured and the angular velocity ( ω ) occurs, the rotation is made, and the progress path combines the rotational speed component and the rotation to form a curved path (P2). In this case, curved path P2 considering speed and rotation is displayed as augmented reality on the transparent display 100 (see S20, FIG. 4 (b) and FIG. 7). The curvature of the curve path P2 displayed is proportional to the speed V1 and inversely proportional to the angular velocity ω .

Thereafter, when the angular acceleration α decreases and the angular velocity ω becomes zero, the linear path P3 is again formed (see FIG. 4C).

The change in the line of sight of the actual user causes the rotation of the main body 90 and changes the skiing or snowboarding direction. The change in the traveling path θ 'can be predicted by multiplying the rotation amount θ of the main body 90 by a constant of 1 or less. Since the change of the progress path ( θ ′) depends on the user's physical ability, it is desirable that this constant is continuously updated while constructing the DB of the rotation amount and the progress path change.

6 and 7 not only display the expected path and the change path (P1, P2 or P3) according to the change in the posture of the user on the transparent display 100, the movement of the object (O) through the camera to recognize the movement path This is a process for notifying the risk through augmented reality when there is a contact point with the predicted change path (P2 or P3) of the user by predicting (M). Therefore, the method further includes a process of analyzing the image of the straight path P1 or the change path P2 or P3 using a camera or predicting the movement path M of the object O, and the user and the user of the object O. When the arrival time between the paths P1, P2, P3 and the contact point of the object movement path M is calculated, if the difference is within a predetermined time (for example, 1 second), it is determined that the collision probability is high and a warning screen is displayed. , May sound a warning (S40). 7 illustrates an example of displaying a collision prediction point and a danger mark on the transparent display 100 as augmented reality.

8 and 9 illustrate an embodiment for detecting a collision risk of a rear region in which a camera cannot analyze an image.

1 and 8, the left sound sensor 61 (first microphone) and the right sound sensor 62 (second microphone) are used to detect a collision risk in the rear region. After recognizing the acoustic signal waveform and removing the noise from the left side and the right side of the main body 90, the predetermined waveform generated by the moving object can be extracted. Since the moving object generates sound waves in one sound source, the moving object may be recognized with similar waveforms on the left and right sides, and thus, the waveform having the maximum synchro ratio among the sound waves measured on the left and right sides may be extracted. Sound waves applied to the left sound sensor 61 are denoted by reference numeral L, and sound waves applied to the right sound sensor 62 are denoted by reference numeral R. As shown in FIG.

The closer the sound wave of the moving object is, the higher the intensity is, and the amplitude of the sound wave input to each of the acoustic sensors 61 and 62 depends on the position of the object. For example, the maximum amplitude of sound waves due to the movement of an object in the left rear at the same distance is measured large in the left sound sensor 61 and relatively small in the right sound sensor 62. On the contrary, the maximum amplitude of the sound wave due to the movement of the object in the right rear side is largely measured by the right sound sensor 62 and small by the left sound sensor 61. Therefore, in order to detect the position of the object, a mixed waveform of sound waves (L, R) having the maximum synchro rate recognized by the left and right acoustic sensors (61, 62) is generated and the maximum amplitude (A) is measured. ) Can be calculated.

If the rate of change A 'with respect to time of the maximum amplitude A is greater than zero, this means that the distance to the object O is reduced and the object is approaching. An object that is not approaching even an object that is close can be judged not to increase the probability of collision. If the rate of change (A ') with respect to time of maximum amplitude (A) is positive and the maximum amplitude (A) is greater than or equal to the set value (S), it means that the object is approaching within a certain distance. There is a need. The set value (S) is a numerical value for the magnitude of the sound wave, which is in decibel units (dB), and can be changed according to the speed of the user. Since the approach speed of the object O is relative to the speed of the user, the faster the speed of the user is, the smaller the set value S needs to be to increase the safety factor.

It is necessary to check whether the object is approaching from the rear right, the rear left, or from the rear of the center. This can be confirmed by comparing the intensity variation of the left waveform (L ') and the variation of the right waveform intensity (R') after measurement. have. When the intensity change rate (L ′) of the left waveform is greater than the intensity change rate (R ′) of the right waveform, it indicates that the vehicle is approaching from the left side, and thus displays the left collision risk as an augmented reality image on the transparent display 100. On the contrary, when the intensity change rate (R ′) of the right waveform is greater than the intensity change rate (L ′) of the left waveform, it means that the vehicle is approaching from the right, so that the right collision risk is displayed as an augmented reality image on the transparent display 100. When the intensity change rate L ′ of the left waveform is similar to the intensity change rate R ′ of the right waveform, it means that the left and right acoustic sensors 61 and 62 are approaching at a similar distance, which means that the object approaches from behind the center. It means that there is a central collision risk display as augmented reality image on the transparent display (100).

In FIG. 9, the augmented reality image of the right collision risk mark is shown as an example, and the danger notice mark (W) is semi-transparently displayed so as not to interfere with another augmented reality image or actual field of view.

Since skis wear goggles and neck warmers, etc., it is difficult to recognize a face, so it is difficult to find a party. FIGS. 10 and 11 are views for explaining an embodiment of a friend find function. As shown in FIG. 10, the memory 80 of the processor 80 stores image information I1, I2, I3, I4, I5, I6, and I7 capable of specifying a party. When executing the friend search mode using the mode selection button 70, the camera 50 of the main body 90 analyzes the people around and evaluates the similarity for each item. Before evaluating the similarity, the similarity rate of the image is measured through image analysis. The similarity rate is determined by comparing the information that can be detected for each item and comparing the color, shape, and brand. For example, the item of FIG. 10 has the same color and shape, but the brand image is not detected and shows a similarity rate of 95%.

Each item has a weight for determining similarity, and the smaller the item, the higher the weight. Normal tops, bottoms and boots are weighted at a high 0.2 because they are not significantly changed, and helmets or hats, goggles and equipment are weighted from 0.1 to 0.15 because other products are sometimes available through wear or rental, Gloves may not be worn, and the frequency of wearing products other than the input product is high due to loss, etc., and the weight of 0.05 is given because the area of the overall image is small. The above items are just examples and may be added or subtracted with information necessary to recognize a specific person, and weights may be changed. In particular, if the rare equipment or clothing is stored, the weight of the corresponding item can be increased to increase the recognition rate. The similarity score may be evaluated by summing scores obtained by multiplying the similarity rate and the weight, and may be recognized as the specific person when the evaluation score of the analysis target is higher than a predetermined level (for example, 75 points) on the image of the specific person stored in the memory.

In FIG. 10, the total similarity scores of the subjects analyzed by the camera using the exemplary items described above were recognized as a group of REOs with a high similarity of 81.5 points.

11 shows the object recognized as a REO on the transparent display 100 through an augmented reality image. An augmented reality image (F1) is displayed on the object analyzed as a single row. In FIG. 11, a name (REO) for highlighting a range of images recognized as an object and specifying a party is displayed as an augmented reality image.

FIG. 12 illustrates an example of a game in which the game mode is operated to set an obstacle such as a virtual gate G on a map and set a path to pass through using the GPS receiver 40. . Since the transparent display 100 can display the gate at a set position using an augmented reality image without establishing the actual gate, it is possible to measure the record of the pre-competition match or race races between users using the same content.

13 is an example of a message 200 sent to the situation room and / or party when the distress mode is selected. By using the GPS receiver 40 to display the current distress position (E) where the emergency situation occurred on the map (M) to inform the distress facts to the party or the situation room, it is possible to wait for follow-up.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various value substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It is evident to those of ordinary knowledge.
