1 Overview

• Backend API for Barcode Scanner Project.

2. Run demo

2.1 Simple demo

from algorithm import Algorithm
with open("config.json", "r") as f:
    config = json.load(f)
algorithm = Algorithm(config=config)
ori_img = cv2.imread("images/1.jpg")
camera_id = "0"
list_infer_imgs = [[ori_img, camera_id]]
list_results = algorithm.process(list_infer_imgs)

2.2 Input/Output format

• Input format: a list of image and camera_id.
• Output format: json. Example:

```
