【摘要】:針對在復雜的掃描環(huán)境下,三維激光掃描點云數(shù)據(jù)容易缺失、噪點多,點云預處理難度大且效果不理想,進而影響后期模型重建精度和效率的問題,該文對融合三維激光掃描和多視圖影像重建兩種技術(shù)進行了研究,提出了一種全新的快速精細化模型重建方法。結(jié)合某工程實例,基于分塊建模的思想,運用該方法完成了數(shù)字三維模型的重建工作。實驗結(jié)果表明,該方法可以建立高精度的三維模型,并在很大程度上提高了建模的效率。
[Abstract]:Aiming at the complex environment scanning, 3D laser scanning point cloud data easy to loss, noise, point cloud pre-processing is difficult and the effect is not ideal, thereby affecting the late model reconstruction accuracy and efficiency, this paper has made a study on the reconstruction of the fusion of 3D laser scanning and multi view images of two kinds of technology, puts forward a a new method of fast fine model reconstruction. Based on a practical engineering block modeling based on the idea of using this method to complete the digital 3D model reconstruction. The experimental results show that this method can establish three dimensional model with high precision, and improves the modeling efficiency to a great extent.
