基于随机编码结构光的双目立体三维测量系统

基于双目立体视觉理论建立的三维测量方法具有非接触、大视场、较高精度以及实时性强等优点，因此在工业众多领域得到广泛的应用。立体匹配是实现双目立体测量的关键技术。为了提高匹配精度和鲁棒性，将一种随机编码结构光投射到被测物体表面，使物体表面具有丰富的纹理信息，从而使立体匹配不受自身表面纹理的影响，而且具有较强的抗外界噪音的能力，满足现场测量的要求。该方法仅需拍摄1次，完成一次三维测量仅需十几秒，因此能够应用到动态场景并且实现快速三维测量。

Binocular Stereo 3D Measurement Based on Random Encoded Structured Light

The 3D measurement method based on binocular stereo vision has many advantages, such as contactlessness, large field of view, high accuracy and real time. It has been applied to many industrial fields. Stereo matching is a key technology in binocular stereo measurement. In this paper, in order to improve matching accuracy and robustness, random pattern is projected onto the object surface to make richly textured, as a result, stereo matching will not be influenced by itself texture and environmental noise in site. In this method, 3D measurement needs just single shot and takes about 10 seconds, so it is rapid and suitable to dynamic scene.
