LF: AOI Get RGB from Image / Camera (B10 models only)

UniStream's AOI functionality supports color recognition. The AOI Get RGB Ladder Function provides tools for real-time and static image processing. 

Notes: 

 

Get RGB from Image

This function enables extracting Red, Green, and Blue (RGB) color values from a pre-captured image stored on the SD card file.

By specifying a Region of Interest (ROI) within the image, this feature efficiently isolates the desired section for analysis. 

 

 

Parameter Name

Purpose

A

Image

Link a tag to provide the stored image path on the SD card, relative to /Media/Camera/ 

This parameter is used to locate and load the image for processing.

B

Region settings for image from file

Defines the region of interest (ROI) within the image that is used for RGB extraction. This can include coordinates, dimensions (width and height), or predefined areas of the image. This allows processing only on specific sections of the image.

If you do not use this parameter, the entire image is processed.

 

C

Status

0 = Success
1 = CPU in progress
2 = Panel in progress
-1 = Internal Error
-2 = File doesn't exist

D

RGB

Returns in percentage the struct containing three REAL tags for the red, green, an blue channel values.

 

Get RGB from Camera

This function refers to capturing and processing live image data directly from a camera connected to the controller and extracting the Red, Green, and Blue (RGB) color values from specific pixels or regions of interest.

 

 

Parameter Name

Purpose

A

Region settings for image from camera

Defines the region of interest (ROI) within the live camera feed for RGB extraction. This can include coordinates, dimensions (width and height), or predefined areas of the image. This allows processing only on specific sections of the image from the camera.

If you do not use this parameter, the entire image is compared.

 

B

Status

0 = Success
1 = CPU in progress
2 = Panel in progress
-1 = Internal Error
-2 = File doesn't exist
-3 = No camera detected

C

RGB

Returns in percentage the struct containing three REAL tags for the red, green, an blue channel values.
