Interactive teaching and training system with simulated night vision goggles

The new type is related to an interactive teaching system, especially an interactive teaching system with simulated night vision goggles.

The infrared night vision device is a military night vision device that utilizes photoelectric conversion technology. It is divided into active and passive: the former uses an infrared searchlight to illuminate the target, and the reflected infrared radiation forms an image; the latter does not emit infrared rays, and relies on the target's own infrared radiation to form a thermal image, so it is also called a thermal imager. The visible light is very weak at night, but the infrared rays that are invisible to the human eye are very rich. Infrared vision devices help people observe, search, aim and drive vehicles at night.

In addition, the low-light night vision device works passively, is safe and reliable to use, and is not easy to expose. Its working distance is related to ambient lighting conditions and weather. Under starlight conditions, people at a distance of 0.8 km and vehicles at a distance of 1.5 km can be observed. However, its action distance and observation effect are greatly affected by meteorology, and it cannot work normally in rain or fog.

There are many occasions in the military that require indirect observation and long-distance transmission of images, thus developing a low-light TV. The image of the twilight TV is clear and the viewing distance is far. In good weather conditions, the camera can be used for distances of more than 10 kilometers. Low-light TV also applies to directional and fixed-point observations, and plays an important role in the surveillance of enemy fixed targets and in the alert and security of our important targets.

The details of the related patents and the technical content of the present invention will be clearly shown in the following detailed description of the three preferred embodiments of the reference drawings.

It should be noted that before the detailed description, similar elements are denoted by the same reference numerals.

Referring to Figures 2 and 3, there is shown a first preferred embodiment of an interactive teaching and training system with a simulated night vision goggle. The first preferred embodiment comprises a main control device 3 and a plurality of student devices 4.

The main control device 3 includes a main control terminal computing unit 31, a main control terminal control interface 32 electrically connected to the main control terminal computing unit 31, and a main control terminal communication unit 33.

Each student device 4 includes a computing unit with the master terminal 31 student-side computing unit 41 for information connection, a student-side data storage unit 42 electrically connected to the student-side computing unit 41, a head-mounted display 43 electrically connected to the student-side computing unit 41, and a student terminal The student terminal control interface 44 electrically connected to the computing unit 41 and a student terminal communication unit 45 connected to the student terminal computing unit 41.

The master computing unit 31 and the plurality of student computing units 41 are computer programs of a general executable program. Preferably, the plurality of student computing units 41 can use a relatively portable tablet computer to move with the student. The master computing unit 31 performs data transmission with the plurality of student terminal computing units 41 by means of a network information connection. Preferably, the wireless information transmission method can be used for digital information transmission. In actual implementation, this should not be limited.

The master control interface 32 is a general mouse keyboard, and an instruction can be input to the master computing unit 31. The plurality of student end manipulation interfaces 44 are general mouses to input commands to the corresponding student end calculation unit 41. The master terminal unit 33 and the plurality of student terminal units 45 are general microphones and earphones, and the master control interface 32 can control one of the master terminal unit 33 and the plurality of student terminal units 45. Or a combination to make a call.

Referring to FIG. 4, each student end computing unit 41 has a display control module 411. Preferably, the display control module 411 is a display auxiliary computing circuit having a general screen and a night vision mirror image to assist the student end. The calculation unit 41 displays the simulated picture in the head mounted display 43.

Head Mount Display (HMD) is a device for displaying images and colors. Usually in the form of an eye mask or helmet, the display is placed close to the user's eyes, and the focal length is adjusted by the optical path to project the image to the eye at a close distance. Head-mounted displays can produce a wide viewing angle in a much smaller volume than a normal display, usually with a viewing angle of more than 90 degrees.

At present, the display of the head-mounted display in the left and right eyes is usually two completely independent display screens, so the head-mounted display generally supports the playback of stereoscopic images. The head-mounted display is currently divided into two types: light-transmissive and non-transparent. The light-transmissive head-mounted display can be used for displaying images, and can also let the user see images behind the display, such as a combat helmet of a fighter. The external image can be seen through the transparent eye mask, and the frame, the line, and the data can be displayed in the transparent eye cover, but the light-transmissive head-mounted display is extremely expensive. In the first preferred embodiment, the non-transparent head-mounted display is used to reduce the cost of construction and maintenance, and the external light can be excluded to simulate the night vision mirror. In actual implementation, this should not be used. Limited.

Each student data storage unit 42 stores at least one image data 421. The image data 421 is a teaching file of a simulated night vision mirror. The plurality of student end computing units 41 can execute a program to read the image data 421 and according to the set. A parameter is displayed on the head mounted display 43. The image data 421 has a plurality of parameter settings such that the screen displayed by the head mounted display 43 is close to the image seen by the actual night vision mirror. The night vision mirror image simulated by the data is not an ordinary green screen. The interactive teaching method of this new type will explain the image data in detail.

The master computing unit 31 sets the parameter setting in the image data 421 by the master control interface 32, and transmits the set parameter settings to the plurality of student terminal calculating unit 41, so that the plurality of student terminal computing units The image data 421 is calculated according to the set parameter setting, and the complex display control module 411 displays the auxiliary calculated image data 421 on the plurality of head mounted displays 43 to display a simulated screen.

Referring to FIG. 5, the main control terminal computing unit 31 of the main control device 3 has a synchronization control module 311, so that the plurality of head mounted displays 43 display the same picture. Preferably, the synchronization control module 311 can The head-mounted display 43 of the plurality of student devices 4 is group-controlled. For example, the number of the plurality of student devices 4 is nine, and each of the three schools can be set. The player devices 4 are divided into a group, and there are three groups. The master computing unit 31 can control the head mounted display 43 of the first group of student devices 4 to display the first simulation screen, and the other two groups of the student device 4 are worn. The display 43 displays the second simulation picture to achieve flexible teaching. In actual implementation, the number of the actual student device 4 and the setting of the instructor and the teaching material should be matched, and should not be limited thereto.

Referring to FIG. 6 , the interactive teaching method of the first preferred embodiment includes a preparation step 901 , a parameter setting step 902 , a program execution step 903 , a screen display step 904 , and a parameter adjustment step 905 . And a synchronization control step 906.

The preparation step 901 is executed first, and the main control end calculation unit 31 issues an instruction to the plurality of student end calculation units 41 to enable the plurality of student end calculation units 41 to open the image data 421. The master computing unit 31 can first determine, by the software program, whether the image data 421 stored in the plurality of student data storage units 42 matches the program executed by the host computing unit 31, so that the host calculates The unit 31 controls the plurality of student end calculation units 41. Preferably, the main control end calculation unit 31 can provide the plurality of student end calculation units 41 to download the files, so that the plurality of student end calculation units 41 execute the image data 412 of the same material. Or, the synchronization control module 311 controls the plurality of student end calculation units 41 to open the image data 412 in a grouping mode. The technology of controlling multiple computers with related programs and by network is known to the industry and will not be described in detail here.

Then, the parameter setting step 902 is executed, and the main control interface 32 controls the plurality of student end calculation units 41 to perform parameter setting on the read image data 421. Since the novel interactive teaching and training system with simulated night vision goggles does not simply process the picture in monochrome, it must consider various night vision goggle characteristics. For example, the passive night vision goggles actually used must rely on the moon or the starry sky. The light that is reflected by the object, or the light emitted by the object itself, is then amplified by the circuit and presented on the night vision goggles. The area with light presents a black shadow, especially the appearance of the shadow after the moonlight illuminates the item, which is currently impossible for ordinary simulators.

Referring to FIG. 7, each image data 421 has a simulated visual parameter data 4211 for simulating a general visual image, an analog night vision mirror parameter data 4212 for simulating a night vision mirror image, and a head-mounted type. The display 43 displays at least one specific target specific target parameter data 4213, an ambient light parameter data 4214 for providing different ambient light settings, a weather change parameter data 4215 for providing different weather settings, and one for providing human eyes. The two-eye asynchronous parameter data 4216 of different pictures is visually viewed from left to right.

The simulated visual parameter data 4211 is roughly divided into a picture of a general scenery in different light. When the main control interface 32 adjusts the complex analog visual parameter data 4211, the corresponding display of the plurality of head mounted displays 43 can be displayed. In general, the scenery under normal vision appears. It is better to simulate the appearance of the aircraft from a distant height overlooking the harbor, the city, or the important construction. In actual implementation, it may also simulate the display of buildings, chariots or enemies by land simulation. It should not be limited to this.

The simulated night vision mirror parameter data 4212 is mainly used to simulate a night vision mirror when the human eye is in poor visibility, and when the main control interface 32 adjusts the complex analog night vision mirror parameter data 4212, the corresponding The screen using the night vision goggles appears on the display screen of the plurality of head mounted displays 43. Preferably, the simulated night vision goggles parameter data 4212 can be matched with the simulated visual parameter data 4211 to enable the learner to know the specific building during the day. The visual picture, as well as the image presented by the night vision goggles at night, help the student to distinguish specific targets when using the night vision goggles.

When the image data 421 executed by the student end computing unit 41 is a simulated high-altitude overhead view screen, the display screen of the specific building or vehicle may be completely different from the daytime. Therefore, the specific target parameter data 4213 of the present invention is displayed on the screen. Specific goals, for example, buildings, cars, trucks, tanks, power plants, refineries, fisheries that appear in theaters Ports, military ports, important roads, and even pavements built by asphalt and pavements built by cement will have different appearances in night vision goggles. This new type will be used to digitize specific targets that can be seen at high altitude. And stored in the specific target parameter data 4213. When the host control interface 32 adjusts or sets the plurality of specific target parameter data 4213, a specific target may appear in the display screen corresponding to the plurality of head mounted displays 43.

The present invention stores the parameters of the moonlight and the starlight in the ambient light parameter data 4214, and cooperates with the specific target parameter data 4213 to present a specific light on the surface of the specific target, especially the moonlight on the ridge line to shield the realism, and The area where the light is not illuminated presents a black shadow, and the performance of the black shadow is not the same even at different heights. When the instructor uses the main control interface 32 to adjust the plurality of ambient light parameter data 4214, the corresponding plural The display screen of the head mounted display 43 displays specific highlights and shadows.

In addition, in different weathers, the display of night vision goggles will be different. Generally speaking, the air is seriously damaged or the light in the severe wind and rain is disturbed, and the picture cannot be presented in the night vision goggles, but in the air. A little dust, or a little fog, a halo effect will appear in the distant view of the night vision goggles. When the instructor uses the main control interface 32 to adjust the multi-day change parameter data 4215, it can be corresponding. The display screen of the plurality of head mounted displays 43 displays a specific weather.

At present, some helicopter helmets provide the function of a single-eye night vision goggle, while the other one of the driving is to monitor various instruments of the helicopter cockpit, which allows the driver to normally control the helicopter while viewing the ground conditions. The present invention simulates the helmet with the monocular night vision goggles, and is set in the two-eye asynchronous parameter data 4216. When the main control interface 32 adjusts the complex two-eye asynchronous parameter data 4216, it can be correspondingly In the display screen of the plurality of head mounted displays 43, a simulated night vision goggle screen is displayed at a glance, and the other visual display is a visual image, that is, a screen in the cockpit.

In addition, the image data 421 of the present invention is also simple. The prompt sign is used to simulate the relevant information prompt screens of the combat helmet horizontal line, height line, aiming mark, etc., so that the students are familiar with the presentation of the military flying helmet. Since the simple lines and data are presented in the picture, it has been familiar to the industry. Technology is not described in detail here.

Then, the program execution step 903 is executed, and the main control interface 32 controls the plurality of student end calculation units 41 to calculate the image data 421 according to the set parameters. Preferably, the plurality of student end data storage units 42 can pre-store a set of preset parameter settings. When the plurality of student end calculation units 41 turn on the image data 421, the calculation can be performed according to the preset parameter settings, so that the instructor does not need to Each time the class is required, the parameters of the image data 421 need to be set each time.

Then, the screen display step 904 is executed, and the complex display control module 411 displays the calculated image data 421 on the corresponding multi-head display 43 to display the simulated screen. Since the speed of computer computing is getting faster and faster, the huge image data 421 of the present invention can be quickly calculated, and the analog screen can be quickly displayed on the head mounted display 43.

After the instructor issues the command from the console control interface 32, the network information is transmitted to the calculation of each student terminal calculation unit 41, and the display screen is displayed on the head of the electrical connection display 43 and is displayed as the master terminal. The calling unit 33 conducts a teaching course for the plurality of student-side talking units 45. For the students who use the plurality of head-mounted displays 43, the simulated pictures appearing in front of the eyes and the teaching contents heard by the ears can be said to be in a synchronous manner. Teaching.

In the screen display step 904, the plurality of student end calculation units 41 can receive the corresponding instruction of the plurality of student terminal control interfaces 44, and display a first indicator in the corresponding plurality of head mounted displays 43 and The display coordinates of the first indicator are controlled, and the plurality of student terminal control interfaces 44 can input a confirmation information, and the student terminal calculation unit 41 can transmit the confirmation information to the master calculation unit 31.

Then, the parameter adjustment step 905 is executed, and the control interface 32 controls the plurality of student end calculation units 41 to perform parameter adjustment on the read image data 421 to change the display of the simulated image in the head mounted display 43. When the main control interface 32 adjusts the complex analog visual parameter data 4211, the complex head mounted display 43 displays a simulated visual picture, and the main control interface 32 adjusts the complex analog night vision parameter data. At 4212, the head-mounted display 43 displays a screen of the simulated night vision goggles.

The instructor using the console control interface 32 can change the simulated picture in the plurality of head mounted displays 43 with the parameter settings provided by the image data 421 to enable the student using the plurality of head mounted displays 43 to view To the picture seen by the simulated night vision goggles, and then the teaching dialogue of the plurality of student terminal communication units 45 with the main control terminal unit 33 is richer and more diverse than the conventional teaching of the conventional night vision goggles. This new model allows students to judge more quickly what the target in the picture appears in the night vision goggles.

Finally, the synchronization control step 906 is executed, and the synchronization control module 311 of the master computing unit 31 can issue an instruction to the plurality of student terminal calculation units 41 to cause the plurality of head mounted displays 43 to display the same screen. The screen displays a second indicator, and the master control interface 32 can synchronously control the display coordinates of the second indicator displayed in the plurality of head mounted displays 43.

Preferably, the interactive teaching and training system with simulated night vision goggles provides an instructor teaching mode and a student testing mode. When in the instructor teaching mode, the main control interface 32 can control the plurality of head mounted displays. A second indicator is displayed in the 43. The second indicator is similar to the currently used mouse pointer, and the master control interface 32 can synchronously control the display coordinates of the second indicator appearing in the plurality of head mounted displays 43 and then match Simultaneously display the simulated picture and the output of the instructor teaching sound teaching, effectively displaying the situation that will occur in the use of the real night vision goggles, and allowing the wearing of the plurality of head mounted displays 43 The students learn and become familiar with them.

In the student test mode, the master computing unit 31 can download the same or different simulated night vision goggles questions in the plurality of student end computing units 41, so that each student end computing unit 41 calculates the simulated nights obtained. The sight glass test questions are displayed in the head-mounted display 43 of the electrical connection. The student wearing the head-mounted display 43 can use the student-side control interface 44 to manipulate the coordinates of the first indicator in the head mounted display 43. The indicator is similar to the mouse indicator, and is separated from the second indicator by different patterns, so that the plurality of students select the target object in the screen or the question that appears, and the plurality of student end calculating unit 41 can select the student. The information is transmitted to the master computing unit 31 to enable the instructor to understand the familiarity of the plurality of students with the night vision goggles, and indeed achieve the effect of interactive teaching training.

Please refer to FIG. 8 , which is a second preferred embodiment of the interactive teaching training system with a simulated night vision goggle. The second preferred embodiment is substantially the same as the first preferred embodiment. Further, the difference is that each student device 4 further includes a sensing unit 46 electrically connected to the student terminal computing unit 41. Each sensing unit 46 can sense the direction of the head mounted display 43 and angular momentum. And transmitting information such as direction and angular momentum to the student-side calculation unit 41 that is electrically connected so that the screen displayed in the head-mounted display 43 can change the screen synchronously with the rotation of the wearer's head. direction.

Preferably, the sensing unit 46 of the student device 4 is an imaging lens disposed on the head mounted display 43 and transmits the captured scene image information to the student connection computing unit 41 of the electrical connection. The unit 41 may mark a specific line or item in the scene information of the captured scene, and calculate a position where the specific line or item moves in the scene information to determine the angle at which the head mounted display 43 is rotated or raised. The distance and orientation of the head mounted display 43 can be determined. In actual implementation, the sensing unit 46 can also be an electronic gyroscope, an electronic north arrow, or other direction that can sense the rotation of the head mounted display 43. The sensor should not be limited to this.

When the student end calculation unit 41 obtains the rotation angle of the head mounted display 43, the information displayed on the screen of the head mounted display 43 is calculated, for example, when the student's head is rotated 15 degrees to the left, the head The screen displayed in the wearable display 43 is moved 15 degrees to the left. When the student's head is 15 degrees above the height, the screen displayed in the head mounted display 43 is moved upward by 15 degrees, when the student changes from the sitting position to the standing position, or When the position of the head mounted display 43 is changed by moving the position, the screen displayed on the head mounted display 43 can be moved up and down in synchronization, or moved left and right, so that the student can feel the real wearing of the night vision goggles.

The image data 421 of the student end data storage unit 42 is associated with the real scene model 51 for displaying the night vision mirror image simulated by the real scene model 51 on the head mounted display 43.

In addition, the sensing unit 46 disposed on the plurality of head-mounted displays 43 is configured to enable the student to rotate the head, and the displayed image can still be aligned with the real-life model 51. The student-side computing unit 41 can Displaying the night vision mirror simulation screen in the head mounted display 43 and displaying the information displayed to the pilot in the aircraft helmet (for example, height information display or aiming target information display, etc.), the instructor can dim the classroom lighting In order to enable the participants to learn and familiarize themselves with the sight of the pilot wearing a flying helmet. Each head mounted display 43 can be calibrated to the screen of the real scene model 51 before use, so that the simulated display screen of the head mounted display 43 is correctly matched with the real scene model 51 for simulation teaching. .
