如何在Linux上离线部署Grounding DINO-CSDN博客

这个博客主要来介绍如何利用Grounding DINO这个项目去进行目标检测的自动化标注。并且给出了相关的代码已经实验验证。

1.数据集准备

2. 开始实验

2.1 批量标注参考代码如下：

import os
import cv2
import torch
from torchvision.ops import box_convert
from groundingdino.util.inference import load_model, load_image, predict, annotate# 配置路径
MODEL_CONFIG_PATH = "groundingdino/config/GroundingDINO_SwinT_OGC.py"
MODEL_WEIGHTS_PATH = "weights/groundingdino_swint_ogc.pth"
PROJECT_ROOT="Auto_label/Project1/" # 自动检测的根路径
IMAGE_FOLDER = PROJECT_ROOT + "images"  # 输入图片文件夹
OUTPUT_FOLDER = PROJECT_ROOT + "detect_results"  # 输出标注图片的文件夹
LABELS_FOLDER = PROJECT_ROOT + "labels"  # 输出YOLO标签的文件夹
CLASSES_FILE = PROJECT_ROOT + "classes.txt"  # 类别文件# YOLO标签格式转换函数

上面的注释非常详细了，就不过多赘述了。

主要根据自己的环境修改以下内容
