Description

Interactive teaching and training system with simulated night vision goggles and method

The invention relates to an interactive teaching system, in particular to an interactive teaching system with simulated night vision goggles and a teaching method using the interactive teaching system.

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 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 display can be smaller than ordinary display The volume of the volume produces a wide viewing angle, 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.

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 interactive teaching and training system with simulated night vision goggles of the present invention 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 shines on the item The tiny light reflected, or the light emitted by the object itself, is magnified by the circuit and presented on the night vision goggles. The small light is magnified, and the area without light appears dark, especially after the moonlight is illuminated. The presentation of shadows is currently not possible with 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 parameters of the present invention are According to 4213, specific targets are displayed on the screen. For example, buildings, cars, trucks, tanks, power plants, oil refineries, fishing ports, military ports, important trunks, etc., which were built in the theater, were even built by asphalt. The pavement and the pavement constructed by the cement will have different differences in the screen presentation of the night vision goggles. The present invention will digitize and store the specific target object at a high altitude, and store it in the specific target parameter data 4213, when the main When the terminal 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.

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, the corresponding In the display screen of the plurality of head mounted displays 43, a night vision mirror is displayed at a glance On the other hand, the other side displays the visual picture, which is the picture in the cockpit.

In addition, the image data 421 of the present invention also has a simple prompt indication for simulating the related information prompt screens of the combat helmet horizontal line, the height line, the aiming sign, etc., so that the student is familiar with the presentation of the military flying helmet, due to the simple lines, The data is presented in the picture and has been familiar to the industry, and will not be described in detail here.

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. The present invention allows the learners to more quickly determine the target in the picture appearing 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.

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.
