With increasing consumer expectations and stringent quality standards, traditional quality assurance (QA) methods are often insufficient. Manual inspection is prone to human error, is inconsistent over time, and cannot scale effectively with production demands.

Fatigue and human error lead to inconsistent defect detection. Production lines often produce thousands of units per minute, making real-time manual inspection impractical. Defective products can harm brand reputation, erode customer trust, and result in costly recalls. Certain defects, like minor scratches or subtle misalignments, are difficult to detect with traditional methods.

Visual inspection is commonly used for quality or defect assessment, in non-production environments, it is used to determine whether the features indicative of a “target” are present and prevent potential negative impacts.
