            capture.Release();
  
        }
    }
}

【运行步骤】

（1）首先依据官方安装教程或者其他网站给的安装教程，安装好yolov8环境

（2）下载模型：https://github.com/ultralytics/assets/releases/download/v8.3.0/yolo11n.pt
（3）导出onnx模型：yolo export model=yolo11n.pt format=onnx dynamic=False opset=12
（4）然后将yolo11.onnx模型放进FIRC\bin\x64\Debug\weights
最后运行项目选择x64 Debug即可，由于初次运行可能报错，如果报错请查看https://blog.csdn.net/FL1623863129/article/details/135424751
