Research on Object Measurement Based on 3D Stereo Vision

In traditional measurement methods, the measurement tools used by people have strong specificity, poor versatility, and time-consuming. They are often only measured for two-dimensional plane geometric quantities. It is impossible to accurately measure some complex three-dimensional surfaces. Therefore, the stereo measurement technology based on 3D reconstruction has increasingly become a hot issue of research. This paper improves the fusion method of the binocular stereo vision measurement system and the TOF measurement system. In order to make the results accurate, before starting the measurement, the binocular and TOF are calibrated, and then the data obtained by the TOF camera is filtered and denoised. On the basis of ensuring accuracy, fast dense reconstruction can be completed. This article will use binocular and TOF camera to detect foam board, bucket and fire extinguisher in order to describe the above process in detail.
