Quality inspection is a very important aspect of manufacturing industries. It satisfies some important objectives of manufacturing industries such as decreasing human labour, during subjective judgment destruction of human error, increasing overall profit of the industry and improved quality of the workpiece. To overcome the constraints of conventional inspection system which were very time consuming and lengthy and cost effective; quality inspection using image based sensor is the system for getting maximum product quality in such lesser time. In this paper we focus on quality inspection using image sensor. we will be focusing on how image based sensor inspection is a very efficient solution for conventional non-efficient inspection systems. The results will offer an overview different approaches of visual inspection using image based sensor, its perks and constraints and specific applications in manufacturing industry.
