+## 模型概述
+
+barometer_reader是基于PaddleX实现对传统机械式指针表计的检测与自动读数功能的模型。该模型首先使用目标检测模型检测出图像中的表计，随后使用语义分割模型将各表计的指针和刻度分割，最后根据指针的相对位置和预知的量程计算出各表计的读数。
+
+## 命令行预测
+
+```
+$ hub run barometer_reader --input_path "/PATH/TO/IMAGE"
+
+```
+
+## API
+
+```python
+def predict(self, 
+            im_file: Union[str, np.ndarray], 
+            score_threshold: float = 0.5, 
+            seg_batch_size: int = 2, 
+            erode_kernel: int = 4, 
+            use_erode: bool = True, 
+            visualization: bool = False, 
+            save_dir: str ='output'):
+```
+
+预测API，用于表针读数。
+
+**参数**
+
+* im_file (Union\[str, np.ndarray\]): 图片路径或者图片数据，ndarray.shape 为 \[H, W, C\]，BGR格式；
+* score\_threshold (float): 检测模型输出结果中，预测得分低于该阈值的框将被滤除，默认值为0.5；
+* seg\_batch\_size (int): 分割的批量大小，默认为2；
+* erode\_kernel (int): 图像腐蚀操作时的卷积核大小，默认值为4；
+* use\_erode (str): 是否使用图像腐蚀对分割预测图进行细分，默认为False;
+* visualization (bool): 是否将可视化图片保存；
+* save_dir (str): 保存图片到路径， 默认为"output"。
+
+**返回**
+
+* res (list\[dict\]): 识别结果的列表，列表中每一个元素为 dict，关键字有 'category\_id', 'bbox', 'score','category', 对应的取值为：
+  * category\_id (int): bounding box框出的图片的类别号；
+  * bbox (list): bounding box数值；
+  * score (float): bbox类别得分；
+  * category (str):  bounding box框出的图片的类别名称。
+
+
+## 代码示例
+
+```python
+import cv2
+import paddlehub as hub
+
+model = hub.Module(name='barometer_reader')
+res = model.predict('/PATH/TO/IMAGE')
+print(res)
+```
+
+## 服务部署
+
+PaddleHub Serving可以部署一个表计识别的在线服务。
+
+## 第一步：启动PaddleHub Serving
+
+运行启动命令：
+
+```shell
+$ hub serving start -m barometer_reader
+```
+
+默认端口号为8866。
+
+**NOTE:** 如使用GPU预测，则需要在启动服务之前，设置CUDA_VISIBLE_DEVICES环境变量，否则不用设置。
+
+## 第二步：发送预测请求
+
+配置好服务端，以下数行代码即可实现发送预测请求，获取预测结果
+
+```python
+import requests
+import json
+import cv2
+import base64
+
+
+def cv2_to_base64(image):
+    data = cv2.imencode('.jpg', image)[1]
+    return base64.b64encode(data.tostring()).decode('utf8')
+
+
+if __name__ == '__main__':
+    # 获取图片的base64编码格式
+    img = cv2_to_base64(cv2.imread("/PATH/TO/IMAGE"))
+    data = {'image': img}
+    # 指定content-type
+    headers = {"Content-type": "application/json"}
+    # 发送HTTP请求
+    url = "http://127.0.0.1:8866/predict/barometer_reader"
+    r = requests.post(url=url, headers=headers, data=json.dumps(data))
+    # 打印预测结果
+    print(r.json())
+```
