Image processing for scanning devices based on laser aimer position

A method, comprising:

• capturing, using a scanning device, a first frame and a second frame of image data related to an object associated with a barcode;
• determining, an absolute difference value between first pixel data for a first pixel column associated with the first frame and second pixel data for a second pixel column associated with the second frame to determine a region of interest comparison between the first frame and the second frame;
• adding, pixel values for the first pixel column and the second pixel column in the region of interest comparison to determine a pixel column number and a maximum accumulated value for the pixel column number;
• estimating, a distance between an optical engine of the scanning device and the barcode based on the pixel column number with the maximum accumulated value with respect to other pixel column numbers;
• and
• performing, image processing with respect to the barcode based on the distance between the optical engine of the scanning device and the barcode.

A scanning device, comprising:

• an optical engine comprising an imager;
• and
• a processing device, wherein the processing device is configured to:
• capture, using the imager, a first frame and a second frame of an image data related to an object associated with a barcode;
• determine an absolute difference value between a first pixel data for a first pixel column associated with the first frame and a second pixel data for a second pixel column associated with the second frame to determine a region of interest comparison between the first frame and the second frame;
• add pixel values for the first pixel column and the second pixel column in the region of interest comparison to determine a pixel column number and a maximum accumulated value for the pixel column number;
• estimate a distance between the optical engine and the barcode based on the pixel column number with the maximum accumulated value with respect to other pixel column numbers;
• and
• perform image processing with respect to the barcode based on the distance between the optical engine of the scanning device and the barcode.
