In this chapter, we focus on keypoint-based point cloud registration which has proven to be among the most efficient strategies for aligning pairs of overlapping scans. We present a novel and fully automated framework which consists of six components addressing (i) the generation of 2D image rep...
With the popularity of multi-source sensors in the field of surveying and mapping, point cloud (PC) data and optical image have been widely used. How to coordinate PC and optical image, and how to establish direct mapping between two kinds of data to realize complementary advantages have ...
DeepI2P: Image-to-Point Cloud Registration via Deep Classification Jiaxin Li Bytedance Gim Hee Lee National University of Singapore Abstract This paper presents DeepI2P: a novel approach for cross-modality registration between an image and a point cloud. Given an image (e.g...
Point-cloud-registration点云配准入门知识点云的概念:点云是在同一空间参考系下表达目标空间分布和目标表面特性的海量点集合,在获取物体表面每个采样点的空间坐标后,得到的是点的集合,称之为“点云”(Point Cloud)。 点云图像是最基础也是最常见的三维图像。那什么是三维图像呢?三维图像是一种特殊的图像信息表达形式...
PDF:DeepI2P: Image-to-Point Cloud Registration via Deep Classification Abstract This paper presents DeepI2P: a novel approach for cross-modality registration between an image and a point cloud. Given an image (e.g. from a rgb-camera) and a general point cloud (e.g. from a 3D Lidar scann...
Reconstructing three-dimensional (3D) point cloud model of maize plants can provide reliable data for its growth observation and agricultural machinery research. The existing data collection systems and registration methods have low collection efficiency
GitHub - XiaoBaiiiiii/colmap-pcd: Image-to-point cloud Registration Tool 摘要 利用并行激光雷达和相机测量来追求测绘结果中的精确缩放和颜色细节,结果受到外部校准和时间同步精度的影响。在本文中,提出了一种新颖的具有成本效益的重建管道,它利用预先建立的激光雷达地图作为固定约束,以有效解决单目相机重建中存在的固...
This paper presents DeepI2P: a novel approach for cross-modality registration between an image and a point cloud. Given an image (e.g. from a rgb-camera) and a general point cloud (e.g. from a 3D Lidar scanner) captured at different locations in the same scene, our method estimates th...
