Detect the position of an object - computer vision.md

Detect the position of an object - computer vision

Problem

Comparing two images: The observed position vs the required position.

Solution using (OpenCV-Python)

  1. Load your image and binarize it.
  2. Use cv2.findContours(thresh, 1, 2) to find the contour of interest object.
  3. Find the bounding rectangle using cv2.boundingRect(cnt) function.

bot's Note

Why bot framework

Developers writing bots all face the same problems:

  • Require I/O
  • Lang and Dialog Skill

REST API

You can create a bot with any programming language by using the Bot Framework REST API. There are three REST APIs in the Bot Framework:.

  • Bot Connector REST API : send and receive messages to channels configured in the Bot Framework Portal.
  • Bot State REST API : enables your bot to store and retrieve state.
