yolov5实例分割跑通以及C#读取yolov5_Seg实例分割转换onnx进行检测部署

一、首先需要训练yolov5_seg的模型，可以去网上学习，或者你直接用我的，

训练环境和yolov5---7.0的环境一样，你可以直接拷过来用。

或者你直接下载我的环境，都喂你嘴里，就看你吃不吃了，

标注就用pip安装labelme就行

标注后是json文件，需要转化成txt

复制代码

import os
import cv2
import json
import numpy as np


def txt_write(x, img_x, img_y, txt):
    data = x['points']
    n = 1
    for x in data:
        for i in x:
            if n % 2 == 0:
                txt.write(' ' + str(round(i / img_x, 6)))
                n += 1
            else:
                txt.write(' ' + str(round(i / img_y, 6)))
                n += 1
    txt.write('\n')


def json2txt(json_path, save_path):
    txt = open(save_path, 'w')
    with open(json_path, "r") as f:
        data = f.read()
    data = json.loads(data)
    img_x = data['imageHeight']
    img_y = data['imageWidth']
    shapes = data['shapes']

    for x in shapes:
        # print(x['label'])
        # 此处面向不同分类，需要改动下面的标签值，如果是多分类，那么需要增加新的if
        # 只是单分类的话，可以直接去掉if，把里面的模块拿出来用

        if x['label'] == 'FG':
            txt.write('0')
            txt_write(x, img_x, img_y, txt)

        if x['label'] == 'KP':
            txt.write('1')
            txt_write(x, img_x, img_y, txt)
        #
        # if x['label'] == 'ssdp':
        #     txt.write('2')
        #     txt_write(x, img_x, img_y, txt)

    txt.close()


# 单文件测试
# save_dir = "/workspace/" #文件路径
# name = 'test'
# save_path = save_dir + name + '.txt' # 也可以是.doc
# json_path = '/json/65161.json'
# json2txt(json_path,save_path)

# 文件夹
json_dir = r'H:\DL\yolov5-seg-master\masketcp\PCB_dataset\labels\train'
save_dir = r'H:\DL\yolov5-seg-master\masketcp\PCB_dataset\labels\train'
files = os.listdir(json_dir)
os.makedirs(save_dir, exist_ok=True)
num = 1
for file in files:
    name = file[0:-5]
    json_path = json_dir + '/' + name + '.json'
    save_path = save_dir + '/' + name + '.txt'
    json2txt(json_path, save_path)
    print(num, '/', len(files), ':', name)
    num += 1

然后训练完成后

转化onnx 用export.py 转化就行

二、部署

下载源码这是一个大佬的代码里面什么都有

https://github.com/guojin-yan/YoloDeployCsharp.git

打开vs2022

安装 OpenCvSharp4 相关的包

openvino 相关的包

剩下的少什么就下载什么就行了

你可能会报错这个错是因为你的框架是net4.6.1左右的但是框架换到net6.0就不会错

修改的方法就是

将这里的

\bin\Debug\dll\win-x64

所有dll库复制到带有.exe的文件夹中

也就是 \bin\Debug 中就可以了

更改参数：

打开

Score_Threshold 置信度也就是小于此值的都被滤掉

NMS_Threshold 非极大值抑制的值，确定框的数量

classes_count_1 类别的个数你有多少类别你就设置几个

W_H_size_1宽高设定

class_names 是你的类别名

然后我们右键dll程序，生成dll库

将YoloSegDll_all\src\YoloV5_Seg_dll\obj\Debug\YoloV5_Seg_dll.dll路径下的dll文件

引用到控件程序中

主程序代码如下
