An Automated Embedded Computer Vision System for Object Measurement

Document Type


Publication Date




Automation is common in many industries. Some tasks, such as object measurement, can easily be automated. The equipment required to perform automated measurements may be cost prohibitive and may prevent widespread deployment in automated point of sale kiosks or product inspection applications. This paper focuses on the development of an optical measurement device that is inexpensive relative to existing systems. The device consists of an image sensor, several laser line projectors, and a microcontroller. The hardware design and configuration of the device is discussed along with the algorithms used to process the captured images and perform the measurement tasks. The conclusion includes a discussion of the performance of the optical measurement device.
