[0046] Example:

[0047] like Figure 1 As shown, in the first aspect, this example provides a flight control test system based on image transmission technology, characterized in that it includes a display module 100, a main control module 200, an internal communication module 300, and a remote communication module 400, wherein:

[0048] The display module 100 is used to obtain the information input by the tester, determine the test items, and display the real-time transmitted video images and data as well as the final test results. The test items are video quality test, target detection test, and data test;

[0049] The main control module 200 is used for embedded software operation, receiving the test items selected by the tester, executing the corresponding test instructions, sending the test signal to the internal communication module, receiving the video and data information through the internal communication module for analysis and calculation, generating the test results, and sending the test results to the display module for display;

[0050] The internal communication module 300 is used to receive the test signal and send the test signal to the display module and the remote communication module;

[0051] The remote communication module 400 is used to receive the test signal sent from the internal communication module, obtain the recorded video and real-time data information, and send the video and data information to the main control module through the internal communication module for analysis and calculation.

[0052] This application uses the display module 100, the main control module 200, the internal communication module 300, the remote communication module 40 and the corresponding related functions of each module, adopts an image transmission-based method, and performs flight control testing based on image transmission technology, so as to achieve multi-faceted testing through test video images and data, thereby improving test efficiency and test accuracy. First, the display module 100 obtains and determines the test items according to the tester's input information, and the test items are one of video quality test, target detection test or data test, wherein the display module 100 mainly adopts a TFT-LCD liquid crystal display or other display module; the main control module 200 sends the test items to the remote communication module 400 through the internal communication module 300, and the internal communication module 300 is a USART serial communication or USB adapter; the test signal sent from the internal communication module 300 is received through the remote communication module 400, and the recorded video and real-time data information is obtained, and the video and data information are sent to the main control module 200 through the internal communication module 300 for analysis and calculation, and the remote communication module 400 is a 4G module; The main control module 200 receives the video images and data transmitted remotely, and performs parsing and calculation through embedded software operation. The embedded software is built in the Linux environment, calls the target tracking model to process the video images, and calls opencv to display the processed video. The main control module 200 uses Huawei Hi3559 as the main control board, multiple ARM architecture CPUs as core processing units, and GPU as an image processing acceleration unit. After the main control module 200 processes the data, it determines the working status of the flight control system based on the calculation results, generates test results corresponding to different test items, and feeds the test results back to the display module for display. The tester determines whether the flight control system is working stably based on the test results, and can repeat the test process based on the test results or select new test items for testing. The collected video images and data are analyzed and calculated. The target detection test of the video images is to place the pre-trained target detection model in the main control module 200. The main control module 200 calls the model to process the video image to obtain the prediction box and confidence. It determines whether the target can be detected based on the training confidence. If the confidence is greater than 0.5, it is considered that the target is detected. The closer the confidence is to 1, the greater the possibility that the detected object is the target; the video image quality detection detects multiple aspects, including brightness abnormalities, chromaticity abnormalities, stripe noise abnormalities, occlusion abnormalities, blur abnormalities, snowflake noise abnormalities, signal loss abnormalities, and screen freezing abnormalities; the data test verifies whether the data transmission is correct through the CRC checksum, and parses the data according to the communication protocol. Through the above-mentioned image transmission technology-based testing of the video and data transmitted by the flight control system, remote contactless testing is realized, compatible with the movable characteristics of embedded systems, and the test efficiency and convenient testing of the flight control system are improved.

[0053] In one embodiment, the main control module 200 includes a video quality test, and detects various image anomalies by calling an image processing algorithm through embedded software.

[0054] Specifically, the brightness anomaly converts a frame of image into a grayscale image, and defines a threshold value below a certain value. The image is darker, and the image is brighter when the threshold value is higher than a certain value; the chromaticity anomaly extracts the chromaticity component H of the image, calculates the histogram of the chromaticity component H, and finds the proportion of the largest bin in the entire histogram. The proportion value is the color cast value; the stripe noise anomaly extracts the chromaticity component of the color image, calculates the DFT spectrum of the chromaticity component, and calculates the number of abnormal bright spots in the spectrum. If it is greater than A, it is considered that a stripe anomaly occurs; the occlusion anomaly binarizes the color image, the dark part is the foreground, and the other part is the background. The foreground is detected for connected regions, and the area of ​​the maximum connected region is obtained. The comparison of this area with the area of ​​the entire image is the occlusion rate; the blur anomaly divides the image into N*M areas, and finds the contrast of each area: (max-min) / max. The total average contrast is the blur rate; the snowflake noise anomaly Convolution templates in four directions of 0°, 45°, 90°, and 135° are usually prepared. The image is first convolved with the four templates, and the minimum absolute values ​​of the four convolutions min are used to detect noise points. The grayscale image gray and the median filter image median are calculated to determine the noise points: fabs(median-gray)>10&&min>0.1. The comparison of the noise points in the entire image is the snowflake noise rate. For signal loss anomalies, the color image is binarized, the black part is the foreground, and the other part is the background. The foreground is detected for connected areas to obtain the maximum connected area. The comparison of this area with the area of ​​the entire image is the signal loss rate. For screen freezing anomalies, one frame is taken from the video every T frames, and the histogram of each frame is calculated. The similarity of the histograms of two adjacent frames is calculated. When the similarity is greater than A, the two frames are considered to be consistent, and when the consistent frames reach B, the screen is considered to be frozen.

[0055] In one example, the display module 100 is used for the tester to select a test item, send instructions to the main control module 200, receive feedback from the main control module and display it.

[0056] In one embodiment, the embedded software in the main control module 200 is also used to receive video images and data, and adopt different processing methods according to the data format. The embedded software is used for video quality testing, target detection testing, and posture data testing.

[0057] The video quality test is used to check whether the video has abnormal brightness, abnormal chroma, abnormal stripe noise, abnormal occlusion, abnormal blur, abnormal snow noise, abnormal signal loss, and abnormal picture freezing;

[0058] The target detection test mainly uses Yolo and other algorithms. The embedded software calls the preset target detection model to perform target detection on the incoming video image data, generate prediction boxes and reasoning confidence, and generate relative motion routes.

[0059] The attitude data test is sent to the main control module 200 through the remote communication module 400, and the embedded software calculates the relevant data according to the communication protocol. The check code in the data is used to test whether an error occurs during the transmission process, and the flight control is tested based on the calculated data value to see whether it is working normally.

[0060] In one embodiment, the power module provides a stable output voltage and power to the system, so that the system can work stably and continuously.

[0061] The remote communication module 300 generates video image data / data based on the video acquisition signal / data acquisition signal and feeds it back to the main control module 200;

[0062] like Figure 2 As shown, in the second aspect, this example provides a flight control test method based on the first aspect above, comprising the following steps:

[0066] S40, sending the video image and data to be tested to the internal communication module through the remote communication module 400, and the internal communication module 300 sends it to the main control module;

[0067] S50, receiving and processing the video image and data to be tested through the embedded software in the main control module 200, processing the corresponding data according to the selected test items, there are two test methods for video images, namely video quality test and target detection test, and verifying and calculating the parameter values ​​of the data according to the communication protocol, and sending the corresponding processed data to the display module for display;

The results of the target detection test will be displayed in the video frame, and the motion trajectory and prediction frame will be directly marked on the video; after the test results are displayed, other parts of the test can be carried out, and the test process can also be repeated based on the judgment results.
