在MATLAB中,可以使用计算机视觉工具箱来实现目标追踪。以下是一些实现目标追踪的步骤:
1. 读取视频文件或者摄像头捕获的视频流。
```matlab
videoFileReader = vision.VideoFileReader('visiontraffic.avi');
```
2. 创建一个视频播放器,用于显示视频和跟踪结果。
```matlab
videoPlayer = vision.VideoPlayer('Position', [100, 100, 680, 520]);
```
3. 选择一个目标并初始化跟踪器。
```matlab
objectFrame = step(videoFileReader);
objectRegion = [x, y, width, height];
objectImage = insertShape(objectFrame, 'Rectangle', objectRegion, 'Color', 'red');
figure; imshow(objectImage); title('Yellow box shows object region');
objectHSV = rgb2hsv(objectFrame);
objectHistogram = hsvHistogram(objectHSV, objectRegion);
```
4. 在每个视频帧中,使用跟踪器来跟踪目标。
```matlab
while ~isDone(videoFileReader)
frame = step(videoFileReader);
hsv = rgb2hsv(frame);
[region, ~] = hueHistogramBackprojection(hsv, objectHistogram, ...
'NumBins', 16);
region = round(region);
offset = 10;
objectRegion = [region(1)-offset, region(2)-offset, ...
region(3)+2*offset, region(4)+2*offset];
objectImage = insertShape(frame, 'Rectangle', objectRegion, ...
'Color', 'yellow');
step(videoPlayer, objectImage);
end
```
