Description

Tracking accuracy test system and method of EO/IR electronic optical equipment {SYSTEM AND METHOD OF TESTING TRACKING ACCURACY OF EO/IR ELECTRO-OPTICAL EQUIPMENT}

The present invention relates to a testing system and method for an EO/IR electro-optical device, and more particularly, to a tracking accuracy testing system and method for an EO/IR electro-optical device using a laser.

The contents described in this part merely provide background information on the present embodiment and do not constitute prior art.

A tracking performance test for conventional EO/IR electro-optical equipment is performed as follows.

First, the EO/IR electro-optical device and the target are separated by 1 to 30 km or more according to the equipment requirements, and then the target is moved at the specified speed. Then, the tracking performance is analyzed after storing the tracking image and the change value of the gimbal of the EO/IR electro-optical device.

However, since the conventional method needs to test the performance of detecting and tracking a long-distance maritime target or an aerial target, not only good weather conditions are required, but also considerable time and effort are required for the tracking performance test.

Specifically, it is necessary to prepare actual targets such as airplanes and ships for each specification of test equipment, and it is also necessary to rent a place to secure a sufficient separation distance between test equipment. In addition, there is a problem that the test is not performed under the same conditions because the environmental conditions are different every time the test is performed.

On the other hand, since the speed of the moving target cannot be precisely controlled, the speed change of the moving target cannot be known from the EO/IR electro-optical equipment, and thus it is impossible to accurately analyze the tracking performance.

In this way, it is not easy to test by satisfying all of the time requirements, spatial requirements, and environmental requirements for performing the tracking performance test.

On the other hand, since the motion of a gimbal is measured using a resolver of the EO/IR electro-optical equipment itself when tracking performance is analyzed, there is a problem in that the measured value varies depending on the error of the resolver for each case.

1 is a schematic diagram of a tracking accuracy test system for EO/IR electro-optical equipment according to an embodiment of the present invention.

Referring to FIG. 1, the tracking accuracy test system 100 of the EO/IR electro-optical equipment includes a target information input device 110, a laser generator 120, a rail 130, a rail driving device 140, and a laser tracking device. (150).

The tracking accuracy test system 100 of the EO/IR electro-optical device 10 is an indoor tracking accuracy test device, and is configured to test the target tracking performance of the EO/IR electro-optical device 10.

When the target information input device 110 inputs target information, the laser generator 120 simulates the target information and directly emits a target simulation laser to the EO/IR electro-optical device 10 .

Here, the laser generator 120 is mounted on a vehicle that can move on the rail 130 and may emit a laser for simulating a target at a specific location or radiate a laser for simulating a target while moving to a specific location.

The rail driving device 140 is configured to drive the movement of the vehicle on these rails, and can accurately mimic the target movement.

Meanwhile, the laser generator 120 generates a laser for measuring jitter and radiates it to the EO/IR electro-optical device 10, and the laser tracking device 150 measures the jitter reflected from the outer surface of the EO/IR electro-optical device 10. It is configured to closely analyze the tracking performance of the EO/IR electro-optical equipment 10 by detecting the laser for measurement using a 4-segment angle sensor.

2 is a block diagram of a tracking accuracy test system for EO/IR electro-optical equipment according to an embodiment of the present invention. 3 and 4 are schematic diagrams of a laser generator according to an embodiment of the present invention, and FIG. 5 is a schematic diagram of a target simulating process according to an embodiment of the present invention.

First, referring to FIG. 2, the tracking accuracy test system 100 of the EO/IR electro-optical device according to an embodiment of the present invention includes a target information input device 110, a laser generator 120, a rail 130, and a rail It may be configured to include a driving device 140 and a laser tracking device 150 .

Hereinafter, a detailed configuration will be described.

The target information input device 110 may be configured to receive target information.

The target information input device 110 may be configured to include a target fixed coordinate input unit 111, a target moving coordinate input unit 112, a target speed input unit 113, a target distance input unit 114, and a target temperature input unit 115. there is.

Hereinafter, a detailed configuration will be described.

The target fixed coordinate input unit 111 may be configured to receive fixed coordinates of a target. It can simulate a fixed target by receiving the fixed coordinates of the target, and it is useful to analyze the detection performance by location by specifying a large number of fixed coordinates.

Here, the fixed coordinates mean coordinates on the rail 130 .

The target movement coordinate input unit 112 may be configured to receive movement coordinates of the target. The movement coordinates of the target are the first movement point and the final movement point on the rail 130, which can be usefully used to analyze the tracking performance of the moving target.

The target speed input unit 113 may be configured to receive a target speed for each coordinate on each movement path on the movement path to the movement coordinates of the target. In the case of a moving target, it can be used to simulate the moving target in various ways using the speed of each coordinate on the moving path while moving from coordinate A to coordinate B. Since the moving target may move slowly and then increase speed, or move quickly and then move slowly, there is an advantage in that various movements can be simulated through this.

The target distance input unit 114 may be configured to receive a distance to the target. Here, the target distance means a distance to a target in a real environment, and this target distance can be used as an input value used to simulate the size of a target or the intensity of a laser for simulating a target. This is because the same target may appear smaller or more blurry if the distance to the actual target is greater, and the same target may appear larger or darker if the distance to the actual target is short.

The target temperature input unit 115 may be configured to receive the temperature of the target. Since the result detected by the EO/IR electro-optical device 10 may vary depending on the temperature of the target, it may be used to simulate the target according to the temperature of the target.

According to an embodiment of the present invention, the target temperature input unit 115 may include a target temperature calculator (not shown), an infrared image acquisition unit (not shown), and an infrared temperature sensor (not shown).

Specifically, the target temperature calculation unit (not shown) may calculate the temperature of the region of the target extracted from the infrared image acquired by the infrared image acquisition unit. The infrared image acquisition unit may acquire infrared images of aircraft, operating platforms, and the like. The infrared image acquisition unit may use a pre-acquired infrared image of a driving platform or the like.

The target temperature calculator (not shown) according to an embodiment of the present invention may calculate the temperature of the target using an infrared temperature sensor capable of measuring the temperature of the target in a non-contact manner. The infrared temperature sensor may sense the temperature of an aircraft, operating platform, or the like. The infrared temperature sensor may calculate the temperature for the data of the driving platform or the like obtained in advance. The target temperature calculator (not shown) may transmit the calculated target temperature to the target temperature input unit 115 .

According to another embodiment of the present invention, the target information input device 110 may further include a target temperature information adjusting unit (not shown).

The target temperature information adjusting unit (not shown) may fix the target temperature information received by the target temperature input unit 115 to a constant value. Also, the target temperature information adjusting unit (not shown) may variably adjust the target temperature information received by the target temperature input unit 115 . For example, the target temperature controller (not shown) converts the temperature of the target received by the target temperature input unit 115 into a predetermined temperature unit (eg, 0.3K) according to a predetermined time unit (eg, 0.5 seconds). ) can be reduced by

The target information input device 110 may output target information including variable target temperature information to the laser generator 120 .

In the case of a real target, since the temperature of the actual target detected by the tracking device is not a fixed value, the target temperature information adjusting unit (not shown) variably adjusts the temperature information of the target received by the target temperature input unit 115. The tracking performance of the tracking accuracy test system of IR electro-optical equipment can be improved.

Also, the laser for measuring jitter may be generated in a wavelength band that the EO/IR electro-optical device 10 cannot detect. In the above case, it may be generated in a wavelength band of 3 μm or less.

As shown in FIG. 4 , the laser for measuring jitter is reflected from the EO/IR electro-optical device 10 and returns, and the 4-segment angle sensor module 124 can receive it.

The quarter-division angle sensor module 124 may be configured to detect an angle change value of a laser for measuring jitter reflected from the surface of the EO/IR electro-optical device 10 . Through this angle change value, a change in the driving direction for target detection of the EO/IR electro-optical device 10 can be known. This can be used to analyze whether the EO/IR electro-optical equipment 10 is tracking the target properly or how precisely it is tracking.
