Quantity verification involves confirming that the number of items matches the specified amount.
The term "quantity" refers to the count of items or people, indicating a predetermined total. Depending on the industry or company, it may also be called quantity check, quantity inspection, quantity counting, or quantity management, but all terms share the same meaning.

Quantity Verification Scenarios

• Checking whether the received quantity matches the specified amount in the work instruction from the previous process.
• Confirming that all necessary components are present in the assembly process of manufacturing.
• Counting defective items when the incoming and outgoing quantities should be the same.
• Verifying that the required number of items fit into the designated case.

Even when following procedural manuals, omissions or errors can occur, leading to overlooked shortages during visual inspections. While visual checks are common due to their simplicity, automated quantity verification devices offer an alternative. Below is a comparison of visual checks with other common counting methods:

Method	Details
Visual Inspection	Counting manually, possibly using tally counters. Visually tracking and counting mentally. Checking item heights. Checking item weights. Ensuring no omissions in trays, jigs, or cases.
Weight Measurement	Using counting scales to determine the number of items based on individual item weight.
Passage Sensors	Counting items as they pass through a sensor, requiring items to move (e.g., drop or move horizontally).
Image Processing	Using cameras to capture images and analyze them to detect and count objects.

Each quantity verification method has its advantages and disadvantages:

Method	Benefits	Drawbacks
Visual	Easy to implement	Prone to counting errors and oversights
Weight	Accurate for items with consistent weight; suitable for heavier items; easy to implement	Not suitable for overlapping parts; less accurate for lightweight items
Passage Sensor	Capable of processing large volumes; can be installed on a production line	Requires items to drop or move along a line, which may damage products; not suitable for precise or lightweight small parts
Image Processing	Ideal for small-batch, diverse products; can count items held in jigs; allows saving images of verification results	Cannot count items that are perfectly overlapped (requires items to be spread out)

This device uses proprietary image processing technology to count the number of parts.
It captures images of parts with a camera, detects the total number of parts, and displays the count on a monitor.
It automates the counting tasks performed during product receiving and shipping.

Parts Counting Software

The system automatically counts the number of randomly placed parts.
Since it automatically recognizes the contours of the parts, no prior registration is required.
