yolov5做可视化界面的话,里面中的detect.py文件怎么转化为可以调用的函数或者类啊,
可以将detect.py中的代码封装为一个类或者函数,然后在可视化界面中调用。具体实现可以参考以下代码示例:
import torch
import cv2
from PIL import Image
from yolov5.models.experimental import attempt_load
from yolov5.utils.general import non_max_suppression, scale_coords
from yolov5.utils.torch_utils import select_device
class YOLOv5Detector:
def __init__(self, weights_path, conf_thresh=0.4, iou_thresh=0.5):
self.device = select_device('')
self.model = attempt_load(weights_path, map_location=self.device)
self.conf_thresh = conf_thresh
self.iou_thresh = iou_thresh
def detect(self, img_path):
img = cv2.imread(img_path)
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
img = Image.fromarray(img)
# Inference
img_tensor = torch.from_numpy(np.array(img)).to(self.device).float()
img_tensor /= 255.0
if img_tensor.ndimension() == 3:
img_tensor = img_tensor.unsqueeze(0)
# Predict
pred = self.model(img_tensor)[0]
# Post processing
pred = non_max_suppression(pred, self.conf_thresh, self.iou_thresh, agnostic=False)
# Get bboxes and labels
bboxes = []
labels = []
for det in pred:
if det is not None and len(det):
det[:, :4] = scale_coords(img_tensor.shape[2:], det[:, :4], img.size).round()
for *xyxy, conf, cls in reversed(det):
bboxes.append(xyxy)
labels.append(int(cls))
return bboxes, labels
在上面的代码中,我们定义了一个YOLOv5Detector类,其中包含了初始化方法和detect方法。在初始化方法中,我们加载了模型权重,并设置了置信度和IOU阈值。在detect方法中,我们首先将输入的图像转换为模型需要的格式,然后进行推理,并进行后处理得到检测结果,最后返回边界框和标签。在可视化界面中,我们可以根据需要调用这个类的detect方法来进行目标检测。
