2.4 Marrying Grounding DINO and GLIGEN
2.5 输入和输出的说明 / 提示
- Grounding DINO accepts an (image, text) pair as inputs.
- It outputs 900 (by default) object boxes. Each box has similarity scores across all input words. (as shown in Figures below.)
- We defaultly choose the boxes whose highest similarities are higher than a box_threshold.
- We extract the words whose similarities are higher than the text_threshold as predicted labels.
- If you want to obtain objects of specific phrases, like the dogs in the sentence two dogs with a stick., you can select the boxes with highest text similarities with dogs as final outputs.
- Note that each word can be split to more than one tokens with differetn tokenlizers. The number of words in a sentence may not equal to the number of text tokens.
- We suggest separating different category names with . for Grounding DINO.
三、环境配置过程
3.1 我的环境
系统：最新的ubuntu系统
显卡：3090
CUDA：11.3
如果您有 CUDA 环境，请确保设置了环境变量 CUDA_HOME。 如果没有可用的 CUDA，它将在 CPU-only 模式下编译。
3.2 配置过程
3.2.1 Clone the GroundingDINO repository from GitHub
git clone https://github.com/IDEA-Research/GroundingDINO.git
下载后即可找到对应的文件夹：
3.2.2 Change the current directory to the GroundingDINO folder
cd GroundingDINO/
3.2.3 Install the required dependencies in the current directory
pip3 install -q -e .
不知道为什么，我这个下载一直报错！换一个新的下载方式：
python setup.py install
但是也会飘红！
这个时候不要害怕，遇到错误的包，直接使用 pip 下载即可，耐得住性子，最后再运行上面的安装命令，即可顺利成功！
3.2.4 Create a new directory called “weights” to store the model weights
mkdir weights
Change the current directory to the “weights” folder：
cd weights
Download the model weights file：
wget -q https://github.com/IDEA-Research/GroundingDINO/releases/download/v0.1.0-alpha/groundingdino_swint_ogc.pth
四、测试
Check your GPU ID (only if you’re using a GPU)：
nvidia-smi
Replace {GPU ID}, image_you_want_to_detect.jpg, and “dir you want to save the output” with appropriate values in the following command：
CUDA_VISIBLE_DEVICES={GPU ID} python demo/inference_on_a_image.py \
-c /GroundingDINO/groundingdino/config/GroundingDINO_SwinT_OGC.py \
-p /GroundingDINO/weights/groundingdino_swint_ogc.pth \
-i image_you_want_to_detect.jpg \
-o "dir you want to save the output" \
-t "chair"
[--cpu-only] # open it for cpu mode
当然了，我们也可以使用 Python 进行测试：
from groundingdino.util.inference import load_model, load_image, predict, annotate
import cv2
model = load_model("./GroundingDINO/groundingdino/config/GroundingDINO_SwinT_OGC.py", "./GroundingDINO/weights/groundingdino_swint_ogc.pth")
IMAGE_PATH = "./GroundingDINO/weights/1.png"
TEXT_PROMPT = "person . bike . bottle ."
BOX_TRESHOLD = 0.35
TEXT_TRESHOLD = 0.25
image_source, image = load_image(IMAGE_PATH)
boxes, logits, phrases = predict(
model=model,
image=image,
caption=TEXT_PROMPT,
box_threshold=BOX_TRESHOLD,
text_threshold=TEXT_TRESHOLD
)
annotated_frame = annotate(image_source=image_source, boxes=boxes, logits=logits, phrases=phrases)
cv2.imwrite("./GroundingDINO/weights/annotated_image.jpg", annotated_frame)
