[C++]使用C++部署yolov10目标检测的tensorrt模型支持图片视频推理windows测试通过

【测试通过环境】
vs2019
cmake==3.24.3
cuda11.7.1+cudnn8.8.0
tensorrt==8.6.1.6
opencv==4.8.0

【部署步骤】
获取pt模型：https://github.com/THU-MIG/yolov10训练自己的模型或者直接使用yolov10官方预训练模型
下载源码：https://github.com/laugh12321/yolov10/tree/nms并安装到环境中
导出onnx：
yolo export model=yolov10n.pt format=onnx opset=13 simplify max_det=100 conf=0.25 iou=0.65 nms

注意导出模型和官方yolov10指令导出的onnx是不一样的，使用yolov10-nms导出模型结构如图

注意一定要是上面类似结构图才能用于这个C++项目
导出tensorrt：

等20分钟左右即可导出需要耐心等待一段时间视个人电脑性能决定，由于tensorrt依赖硬件不一样电脑可能无法共用tensorrt模型，所以必须要重新转换onnx模型到engine才可以运行。请勿直接使用提供的engine模型进行直接测试，否则可能无法正常运行
trtexec --onnx=yolov10n.onnx --saveEngine=yolov10n.engine --fp16

下载安装vs2019勾选桌面C++安装
git clone https://github.com/laugh12321/TensorRT-YOLO
cd TensorRT-YOLO
xmake f -k shared --tensorrt="C:/Program Files/NVIDIA GPU Computing Toolkit/TensorRT/v8.6.1.6"
xmake -P . -r
将编译好的deploy.dll和deploy.lib文件放到yolov10-tensorrt-cplus/lib文件夹
编译源码yolov10-tensorrt-cplus
运行命令：
