Description
1、前期模型训练按照下面的项目方式进行：
https://aistudio.baidu.com/projectdetail/3429765?channelType=0&channel=0
2、通过PaddleOCR导出模型
python tools/export_model.py -c ./configs/det/ch_PP-OCRv3/ch_PP-OCRv3_det_student.yml -o Global.pretrained_model=./output/dianbiao_ch_PP-OCR_V3_det/best_accuracy Global.save_inference_dir=./inference/det_db
3、模型转换成serving可以识别的
python -m paddle_serving_client.convert --dirname ./det_db/ --model_filename inference.pdmodel --params_filename inference.pdiparams --serving_server ./ppocr_det_v3_serving/ --serving_client ./ppocr_det_v3_client/
4、启动模型Serving服务
python3 -m paddle_serving_server.serve --model /opt/ammeter_identify_mode/ppocr_det_v3_serving/ --port 9812
5、配置文件serving_client_conf.prototxt
` feed_var {
name: "x"
alias_name: "x"
is_lod_tensor: false
feed_type: 1
shape: 3
}
fetch_var {
name: "sigmoid_0.tmp_0"
alias_name: "sigmoid_0.tmp_0"
is_lod_tensor: false
fetch_type: 1
shape: 1
}`
6、客户端调用代码：
` from paddle_serving_app.reader import *
from paddle_serving_client import Client
import cv2, json, datetime, os,numpy as np
import numpy as np
parent_directory = os.path.dirname(os.path.abspath(file))
client = Client()
#client.load_client_config(os.path.join(parent_directory, 'serving_client_conf.prototxt'))
client.load_client_config('./serving_det_client_conf.prototxt')
client.connect(['****:9812'])
preprocess = Sequential([
File2Image(), BGR2RGB(),
Resize(
(960, 960), interpolation=cv2.INTER_LANCZOS4), Div(255.0),Transpose((2, 0, 1))
])
im = preprocess('./P23030907100210.jpg')
fetch_map = client.predict(
feed={
"x": im,
},
fetch=["sigmoid_0.tmp_0"],
batch=False)
detections = fetch_map["sigmoid_0.tmp_0"]`
输出：
print(fetch_map)
{'sigmoid_0.tmp_0': array([[[[6.7720975e-08, 1.3140065e-07, 1.9094442e-08, ...,
2.3576363e-09, 7.7910184e-10, 4.4165565e-09],
[6.3383972e-08, 1.4166790e-07, 3.6551061e-08, ...,
4.6193835e-09, 1.3099265e-09, 4.5741602e-09],
[2.5273311e-08, 1.4597879e-07, 3.7196685e-08, ...,
6.0767689e-09, 7.5343232e-10, 1.7367194e-08],
...,
[4.4501288e-08, 3.6136807e-08, 7.8183229e-09, ...,
5.6374336e-08, 1.7245652e-08, 2.9781738e-08],
[1.5184209e-08, 7.0195000e-08, 1.4452498e-08, ...,
5.4933416e-08, 9.6213251e-09, 1.3786045e-07],
[7.2296395e-08, 3.9937358e-08, 2.8997006e-08, ...,
1.5954635e-07, 4.4072682e-08, 2.0925140e-07]]]], dtype=float32)}
我疑问的是这个结果是否正确？这个检测模型为什么没有告诉我检测的四点坐标？
