生成物体位置图的代码主要涉及到目标检测和实例分割的相关操作,以下是一个示例代码,你可以参考它进行修改和调整:
```
import cv2
import numpy as np
import random
import colorsys
# 加载模型和数据集
model = MaskRCNN(mode="inference", config=config, model_dir=MODEL_DIR)
model.load_weights(COCO_MODEL_PATH, by_name=True)
class_names = ['BG', 'person', 'bicycle', 'car', 'motorcycle', 'airplane', 'bus', 'train', 'truck', 'boat', 'traffic light', 'fire hydrant', 'stop sign', 'parking meter', 'bench', 'bird', 'cat', 'dog', 'horse', 'sheep', 'cow', 'elephant', 'bear', 'zebra', 'giraffe', 'backpack', 'umbrella', 'handbag', 'tie', 'suitcase', 'frisbee', 'skis', 'snowboard', 'sports ball', 'kite', 'baseball bat', 'baseball glove', 'skateboard', 'surfboard', 'tennis racket', 'bottle', 'wine glass', 'cup', 'fork', 'knife', 'spoon', 'bowl', 'banana', 'apple', 'sandwich', 'orange', 'broccoli', 'carrot', 'hot dog', 'pizza', 'donut', 'cake', 'chair', 'couch', 'potted plant', 'bed', 'dining table', 'toilet', 'tv', 'laptop', 'mouse', 'remote', 'keyboard', 'cell phone', 'microwave', 'oven', 'toaster', 'sink', 'refrigerator', 'book', 'clock', 'vase', 'scissors', 'teddy bear', 'hair drier', 'toothbrush']
# 加载图像并进行目标检测和实例分割
image = cv2.imread(IMAGE_PATH)
results = model.detect([image], verbose=0)
r = results[0]
# 根据目标的边界框和掩码生成物体位置图
height, width = image.shape[:2]
mask = np.zeros((height, width, 3), dtype=np.uint8)
colors = random_colors(len(r['rois']))
for i, roi in enumerate(r['rois']):
class_id = r['class_ids'][i]
mask = cv2.fillPoly(mask, roi.reshape(1, -1, 2), colors[i])
mask = cv2.putText(mask, class_names[class_id], (roi[1], roi[0] + 20), cv2.FONT_HERSHEY_SIMPLEX, 0.5, colors[i], 2)
# 显示原始图像和物体位置图
cv2.imshow('Original Image', image)
cv2.imshow('Object Location Image', mask)
cv2.waitKey(0)
cv2.destroyAllWindows()
```
其中,`random_colors` 函数用于生成不同颜色的掩码,`cv2.fillPoly` 函数用于将掩码填充到图像中,`cv2.putText` 函数用于在目标区域绘制类别名称。你可以按照自己的需求进行修改和调整。
