A Low Cost Stereovision Sensor for Non-Contact Measurement Purpose

In this paper, we propose a cheap stereovision sensor. It is made of two Webcams based on low cost CMOS technology imaging sensors. Computation and images' acquisitions are performed by a standard Computer (PC). We first focus on the advantages of such a system on CCD-based technologies, and then we explain how the tri-dimensional measurements can be obtained. Before concluding, we give some experimental results expressing the effectiveness of the approach
