Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only examples of the present invention, and are not intended to represent all of the technical ideas of the present invention, so that various equivalents and modifications may be made thereto .

Hereinafter, an image automatic test platform of an aviation electronic device according to the present invention and an image automatic test method of an avionics device using the same will be described with reference to the accompanying drawings.

FIG. 3 is a block diagram showing a configuration of an automatic image test platform of an aviation electronic device according to an embodiment of the present invention, and FIG. 4 is a block diagram showing the configuration of an automatic image test platform of an aviation electronic device according to the present embodiment.

3 and 4, the automatic image testing platform 1 of the aviation electronic device according to the present embodiment includes an automatic test control unit 100, a captured image generating unit 200, an automatic image comparing unit 300, And may include a motion simulator 400.

The automatic test control unit 100 may include a command editor 110 and an auto test planner 130. The comment editor 110 allows the user to create a command. The auto-test planner 130 can plan the commands generated by the user in accordance with the order so that one scenario file can be generated. The auto test planner 130 sends an instruction to the automatic image comparator 300 and receives the inspection result of the visual image displayed on the multifunctional visualizer 10. [ In this manner, the user can generate a scenario for checking the displayed image through the automatic test control unit 100 and a scenario for checking the displayed image.

The automatic test control unit 100 may be connected to the display device 101. The display device 101 outputs the inspection result of the received image to the automatic test control unit 100. [ Therefore, the user can easily check the test result through the display device 101. [

Meanwhile, the captured image generating unit 200 generates a captured image that captures a real time image currently being displayed on the multi-function viewer 10 in real time. The captured image generating unit 200 is connected to the automatic image comparing unit 300. The captured image captured by the captured image generating unit 200 may be transmitted to the automatic image comparing unit 300 in real time.

The automatic image comparison unit 300 connected to the automatic test control unit 100 and the captured image generation unit 200 may include a database 310, an image management module 330, and an image comparison processor 350 .

In the database 310, a reference image serving as a reference for inspection of a vision image is stored. The image management module 330 is coupled to the database 310. A user may use the image management module 330 to store a reference image in the database 310, or to manage a reference image, such as an update of a reference image.

The image comparison processor 350 is connected to the automatic test control unit 100 and the captured image generation unit 200. The image comparison processor 350 may receive the command generated from the automatic test control unit 100 and receive the captured image in real time from the captured image generation unit 200. [ The image comparison processor 350 compares the reference image and the captured image according to the instruction, and transmits the comparison result of the reference image and the captured image to the automatic test control unit 100.

Here, the comparison method of the reference image and the captured image may use at least one of a matching score method and a mismatch check method.

The matching score method scales the matching rate by converting the color value of the portion to be compared between the reference image and the captured image into an average value. The mismatch check method compares gray values between the same pixels of the reference image and the captured image. If there is an error in the pixel values of the reference image and the captured image, the resultant value may be represented by another color such as red.

When the reference image and the captured image are compared using either of the matching score method and the mismatch check method, the inspection speed can be improved. By using both the matching score method and the mismatch check method, The accuracy of the inspection can be improved even if the inspection speed is slightly delayed.

In this manner, the automatic image comparison unit 300 receives the command from the automatic test control unit 100 and sequentially checks the captured image and the reference image to check the displayed image. The result of the comparison between the captured image and the reference image may be displayed on the screen through the automatic test control unit 100, and a report may be generated and stored in a predetermined folder.

On the other hand, the touch motion simulator 400 touches the multifunctional previewer 10 to display the multifunctional previewer 10 in a desired image to be inspected.

The touch motion simulator 400 includes a driving control unit 401, a touch pin 410, an actuator 430, a first guide 450, a second guide 470, a first driving motor 451, An actuator 471 and an actuator 430.

The driving control unit 401 is connected to the image automatic comparing unit 300. The driving control unit 401 controls the position of the touch pin 410 that touches the multi-function visualizer 10 according to a command input to the automatic image comparing unit 300. [ The touch pin 410 is provided to touch the screen of the multifunctional visualizer 10. The actuator 430 supports the touch pin 410. The actuator 430 transfers the touch pin 410 toward the multifunctional speaker 10 so that the touch pin 410 can touch the multifunctional speaker 10. The first guide 450 supports the actuator 430. The first guide 450 is disposed so as to correspond to the longitudinal direction of the multifunctional projector 10. The first driving motor 451 feeds the actuator 430 along the first guide 450. The second guide 470 supports the first guide. The second guide 470 is disposed in a direction intersecting the first guide 450 so as to correspond to the transverse direction of the multifunctional projector 10. The second driving motor 471 feeds the first guide 450 along the second guide 470.

Hereinafter, a method of automatically testing an image of an aviation electromagnetic device according to the present invention will be described.

5 is a flowchart illustrating a method of automatically testing an image of an aviation electronic device according to the present embodiment.

First, the user uses the image management module 330 to store in the database 310 a reference image for inspection of a displayed image displayed on the multi-function viewer 10.

Then, the user establishes an automatic test plan and files the command using the comment editor 110 according to the established automatic test plan. In addition, the user constructs a scenario by planning the commands generated using the AutoTest Planner according to the order.

When preparation for the image automatic test of the multifunctional vision device 10 is completed, the user operates the automatic test control unit 100 to execute the image automatic test. As the image automatic test is executed, the auto test planner 130 transmits the stored command to the automatic image comparator 300 according to the scenario. (Step S11)

The automatic image comparing unit 300 receives the command transmitted from the auto test planner 130. [ (Step S13)

At this time, the multifunctional visualizer 10 should display a visual image desired to be inspected. Accordingly, in order to display the visualized image desired to be inspected on the multifunctional visualizer 10, the drive control unit 401 drives the touch motion simulator 400 according to the instruction received by the automatic image comparing unit 300.

That is, the instruction word received by the automatic image comparison unit 300 may include call information of a vision image for displaying an image corresponding to an inspection target. The driving control unit 401 controls the first driving motor 451, the second driving motor 471 and the actuator 430 to touch the multifunctional visualizer 10 according to the calling information of the displayed image, . The touch pin 410 supported by the actuator 430 can touch the multifunctional preview device 10 according to the driving of the first drive motor 451, the second drive motor 471 and the actuator 430. (Step S15)

In this way, the touch pin 410 touches the multifunctional visualizer 10, and the multifunctional visualizer 10 displays the visual image to be inspected. At this time, the captured image generating unit 200 transmits the captured image captured by the multi-function viewer 10 to the image comparison processor 350.

The image comparison processor 350 calls the reference image corresponding to the captured image from the database 310, and compares the captured image with the reference image. That is, the image comparison processor 350 compares the captured image with the reference image using at least one of a matching score method and a mismatch check method. (Step S17)

The image comparison processor 350 transmits the result of the comparison between the captured image and the reference image to the automatic test control unit 100. The automatic test control unit 100 outputs the comparison result between the captured image and the reference image to the display device 101. [

The user can easily check whether the vision image is normal or not by checking the inspection result outputted to the display device 101. [
