📦 資料集

cvat2 project 5（factory_ppe_v20260426_pool）：132 tasks, ~120K imgs。每張 person bbox 切 crop（15% padding）→ 307,569 person crops（p5+p12 合併）。

🚀 模型用法

import torch, torch.nn as nn
import timm
from PIL import Image
import torchvision.transforms as T

ckpt = torch.load("factory_ppe_v20260503_best.pt", weights_only=False)
class GenericClassifier(nn.Module):
    def __init__(self, backbone, n_attr, feat_dim):
        super().__init__()
        self.backbone = timm.create_model(backbone, pretrained=False, num_classes=0, global_pool="avg")
        self.dropout = nn.Dropout(0.3); self.cls = nn.Linear(feat_dim, n_attr)
    def forward(self, x): return self.cls(self.dropout(self.backbone(x)))

model = GenericClassifier(ckpt["backbone_name"], len(ckpt["attrs"]), ckpt["feat_dim"]).cuda().eval()
model.load_state_dict(ckpt["model_state"])
attrs = ckpt["attrs"]; thr = ckpt["thresholds"]

tf = T.Compose([T.Resize((384,192)), T.ToTensor(),
                T.Normalize([0.485,0.456,0.406], [0.229,0.224,0.225])])

def predict(person_crop_pil):
    x = tf(person_crop_pil).unsqueeze(0).cuda()
    with torch.no_grad():
        probs = torch.sigmoid(model(x))[0].cpu().numpy()
    return {a: (float(probs[i]), float(probs[i]) >= thr[a]) for i, a in enumerate(attrs)}

Live RTSP / Cascade 整合
