使用Matlab检测行驶中的车辆的车辆信号灯

Question

嗨，我真的是图像处理和Matlab的真正新手。

我试图使用Matlab中的“ vision.forgroundDetector”检测交通视频的车辆。

但是现在我想确定车辆转弯时车辆信号灯是亮还是灭。

我尝试了一些代码，但是它永远都行不通，而且我不知道在哪里写代码，编写的代码也行不通。

有人可以帮助我识别行驶中的车辆的信号灯吗？ 您可以通过此链接找到我使用的视频  “ https://www.youtube.com/watch?v=jjlBnrzSGjc”

这是我的代码：

    foregroundDetector = vision.ForegroundDetector('NumGaussians', 3, ...'NumTrainingFrames', 50);

videoReader = vision.VideoFileReader('vi.mp4');
for i = 1:150 

    figure; imshow(frame); title('Video Frame');
figure; imshow(foreground); title('Foreground');




    videoPlayer = vision.VideoPlayer('Name', 'Detected Cars');
    videoPlayer.Position(3:4) = [650,400];  % window size: [width, height]
    se = strel('square', 3); % morphological filter for noise removal

    no = {'0','00-0000'};
    num =1;
    k = 10;
    m=0




    while ~isDone(videoReader)

    frame = step(videoReader); % read the next video frame

    % Detect the foreground in the current video frame
    foreground = step(foregroundDetector, frame);

    % Use morphological opening to remove noise in the foreground
    filteredForeground = imopen(foreground, se);

    blobAnalysis = vision.BlobAnalysis('BoundingBoxOutputPort', true, ...
    'AreaOutputPort', false, 'CentroidOutputPort', false, ...
    'MinimumBlobArea', 150);

    % Detect the connected components with the specified minimum area, and
    % compute their bounding boxes
    bbox = step(blobAnalysis, filteredForeground);

    % Draw bounding boxes around the detected cars
    result = insertShape(frame, 'Rectangle', bbox, 'Color', 'green');

    % Display the number of cars found in the video frame
    numCars = size(bbox, 1);
    m = m+ numCars;   
%st = {'JRW-2731','BCR-5890','WJ-6629','MW-5587','RV-6929','BN-8944','AN-7037','BI-7899','BI-7899','RX-7294','TL-9090'};
 noplat;

    result = insertText(result, [10 50; 10 100], no, 'BoxOpacity', 1, ...
        'FontSize', 14);

    step(videoPlayer, result);  % display the results
%    step(videoPlayer, result1);
end

release(videoReader); % close the video file 

这是下一个文件；

    if m>6800 && k == 10
        no = {'1','DAE-4321'};
        k = k-1;
        end
     if m>9600 && k==9
        no = {'2','204-0024'};
        k = k-1;
        end
     if m>15000 && k==8
        no = {'3','QK-BG18'};
        k = k-1;
        end
     if m>23700 && k==7
        no = {'4','KT-7349'};
        k = k-1;
        end
     if m>25000 && k==6
        no = {'5','K2-1479'};
        k = k-1;
     end
     if m>25800 && k==5
        no = {'6','BG-5218'};
        k = k-1;
        end
     if m>33300 && k==4
        no = {'7','B2-8697'};
        k = k-1;
        end
     if m>37900 && k==3
        no = {'8','PQ-1374'};
        k = k-1;
     end   
     if m>90500 && k==2
        no = {'9','RX-7294'};
        k = k-1;
     end
     if m>97000 && k==1
        no = {'10','TL-9090'};;
        k = k-1;
     end
