Braille Printing Plates

Posted in Dark Field Illumination, Featured, Inspection, Object Location, OCR (Optical Character Recognition), Other

The Challenge: To be able to detect and identify the braille characters marked on the surface of a metal plate. Our Solution: The braille alphabet was pre-programmed into the database for reference once the characters were identified with the machine vision system and lighting solution. Using a Dark Field Lighting Technique we were able to identify the braille characters on the surface of the product. The light does not fall directly onto the objective and the majority of the region of interest is dark, while the affected areas on the surface, the braille characters, appear bright. Once the impressions were identified and segmented, they were then referenced to the database and the string of characters were identified.

Bread Inspection

Posted in Colour Inspection, Diffuse Dome Light, Featured, Flaw Detection, Food & Beverage, Inspection, Presence/Absence, Uncategorized

The Challenge: Our customer wanted to be able to check the colour of every loaf to ensure that the ‘bake time’ was correct. The loaves exit the oven in batches of 12 tins.  The customer wanted to introduce a ‘closed loop’ system whereby consistent under or over baking adjusted the conveyor speed through the oven in order to compensate accordingly. Our Solution: A high resolution, colour area scan camera was installed along with diffuse LED lighting. The colour of each loaf in the batch is analysed and based upon statistical trend analysis the control system PLC adjusts the line speed as required. Additionally, individual loafs which fall outside acceptable colour limits are rejected from the line downstream. If more than 5 consecutive loafs are rejected the camera sends an ’emergency’  signal to the PLC so that the operator knows there was a major problem on the...
