电路板铜线尺寸测量，效果在文件中有演示 固定位置自动测量效果说明.pdf。

• Install the libraries in the file requirements.txt with the script below:
  pip3 install -r requirements.txt

• Run the HTTP server with the script like this below:
  python3 manage.py runserver 127.0.0.1:8000

• Create a HTTP API request to get the response, ues POST request method, the image should be encoded by base64, that means it's a string format. Another parameter is shape in URL query parameters, it means one particular shape:
  127.0.0.1:8000/measurement?shape=1

Prepare model

python manage.py makemigrations measurement
python manage.py migrate

Run data within Docker

On Ryzen 5 CPU the pre-create check fails, even though SVM is enabled in the BIOS, this can be solved with skipping that check via

set VIRTUALBOX_NO_VTX_CHECK=true
docker-machine create -d virtualbox default

Then the postgres image can be pulled and started with following commands:

docker run --name aoi-db -p 5432:5432 -e POSTGRES_PASSWORD=aoi2019 -d postgres
docker exec -it aoi-db psql -U postgres

And then within the psql command line

create database circuit_board;
\w circuit_board
create table templates
(
  id           serial primary key,
  shape        varchar(10),
  name         varchar(30),
  top_left     float[],   -- 左上
  bottom_right float[],   -- 右下
  direction    varchar(1) -- 水平: 0, 垂直: 1
);

Start the AOI program with

set PG_HOST=127.0.0.1
set PG_PASSWORD=123456
python manage.py runserver 127.0.0.1:8000
