METHOD AND APPARATUS FOR DETECTING FOREIGN OBJECT INCLUDED IN INSPECTION TARGET - A simplified explanation of the abstract
This abstract first appeared for US patent application 18346824 titled 'METHOD AND APPARATUS FOR DETECTING FOREIGN OBJECT INCLUDED IN INSPECTION TARGET
Simplified Explanation
The patent application describes a method for detecting foreign objects in an inspection target using image data.
- The method involves acquiring first image data for the target, which includes pixel values for a specific wavelength band group.
- The first image data is analyzed to identify pixel regions that meet a certain condition, indicating the presence of a foreign object.
- Second image data is then acquired for the identified regions, which includes pixel values for a larger number of wavelength bands.
- The second image data is analyzed to determine pixel regions that meet another condition, confirming the presence of a foreign object.
- Information about the confirmed foreign object regions is then outputted.
Potential applications of this technology:
- Quality control in manufacturing processes to detect foreign objects in products.
- Security screening at airports and other high-security areas to identify prohibited items.
- Food safety inspections to detect foreign objects in food products.
Problems solved by this technology:
- Efficient and accurate detection of foreign objects in inspection targets.
- Reducing the risk of foreign objects causing harm or damage in various industries.
Benefits of this technology:
- Improved safety and quality control in manufacturing and inspection processes.
- Faster and more reliable detection of foreign objects.
- Reduction in product recalls and potential liability issues.
Original Abstract Submitted
A method for detecting a foreign object included in an inspection target includes acquiring first image data for the target, for which pixels each have a pixel value for a first band group including one or more wavelength bands; determining, from the first image data, one or more pixel regions that satisfy a first condition to be one or more first foreign object regions; acquiring second image data for one or more regions including the first foreign object regions, the one or more regions having pixels each of which has pixel values for a second band group including a larger number of wavelength bands than the first band group; determining, from the second image data, one or more pixel regions that satisfy a second condition to be one or more second foreign object regions, in which the foreign object is present; and outputting information regarding the second foreign object regions.
