Draw Point

Draw Point on Image Node Documentation

The Draw Point node in AugeLab Studio allows you to draw points on an input image at specified coordinates.

Node Overview

The Draw Point node takes an input image and a list of point coordinates as inputs and provides the following output:
  1. 1.
    Image: The input image with the drawn points.

Node Properties

  • Node Title: Draw Point
  • Node ID: OP_NODE_DRAW_POINT

Inputs

The Draw Point node has the following input sockets:
  1. 1.
    Image: The input image on which the points will be drawn.
  2. 2.
    Points: The coordinates of the points to be drawn on the image.

Outputs

The Draw Point node has the following output socket:
  1. 1.
    Image: The output image with the drawn points.

Node Interaction

To draw points on the image:
  1. 1.
    Connect the input image to the Image input socket of the Draw Point node.
  2. 2.
    Connect a list of point coordinates (e.g., from a previous node or a constant node) to the Points input socket.
  3. 3.
    Run the pipeline.
  4. 4.
    The output image will show the input image with the points drawn at the specified coordinates.

Implementation Details

The Draw Point node uses the OpenCV library to draw points on the input image. It takes the list of point coordinates as input and uses the cv2.circle function to draw the points on the image. The node allows for drawing multiple points by accepting a list of coordinates.

Usage

  1. 1.
    Drag and drop the Draw Point node from the node library onto the canvas in AugeLab Studio.
  2. 2.
    Connect the input image to the Image input socket of the Draw Point node.
  3. 3.
    Connect a list of point coordinates (as a list or tuple) to the Points input socket.
  4. 4.
    Run the pipeline.
  5. 5.
    The output image will show the input image with the points drawn at the specified coordinates.

Notes

  • The Draw Point node is useful for visualizing specific points of interest on an image.
  • It allows you to draw single or multiple points on an image by providing the coordinates.
  • The node provides the output image with the drawn points for further analysis or visualization.
That concludes the documentation for the Draw Point on Image node in AugeLab Studio. Use this node to draw points on images at specified coordinates for visualization or analysis purposes.
