Dimension Measurement of objects has been one of the most important issues in the production process. Related to recent advances in measuring apparatus, optical methods have been focused a lot of attention due to their special advantages. In this study, we have investigated the feasibility of using high power LEDs and telecentric system for improving system features. In the signal processing section, the edge detection has been carried out to obtain the outside dimension of the test object. This technique is capable of high resolution and high speed measurement of dimensions and thus has great potential for using in industrial automation systems.
