Computer-aided inspection (CAI) is the use of software tools to assess manufactured objects. It is closely related to computer-aided design (CAD) and computer-aided manufacturing (CAM). Its primary purpose is to allow engineers to more quickly and precisely assess the physical properties of manufactured objects. These properties can include dimensions, material consistency, roughness and roundness.
CAI has applications in industries ranging from food production to aerospace, commonly being used in the quality assurance step of the manufacturing process. It involves comparing manufactured objects with a CAD model, technical drawing or data sheet to ensure that the finished product is within specification and meets design intent.
CAI machines can use a variety of technologies depending on the material of the product to be inspected, the properties to be measured, and the precision required.
Digital cameras are frequently use
