无人驾驶汽车行驶是连续时空的三维运动,汽车周围的目标不可能突然消失或者出现,因此,对于感知层而言,稳定可靠的多目标跟踪(Multi-object tracking,MOT)意义重大.针对传统的目标关联和固定生存周期(Birth and death memory,BDM)管理的不足,提出基于边界交并比(Border intersection over union,BIoU)度量的目标关联和自适应生存...
During the last decade, 3D integrated surveys and BIM modelling procedures have greatly improved the overall knowledge on some Brazilian Modernist buildings. In this framework, the Casa de Vidro 3D su...
Smart city is a connection of physical and social infrastructure together with the information technology to leverage the collective intelligence of the city. Cities will build huge data centres. Thes...
The paper reviews that there are several issues and challenges in order to implement full 2D and 3D Spatial Data Infrastructure (SDI) in Oman. The state of current 2D SDI and 3D geospatial data has be...
Ground-penetrating 2D radar scans are captured in road environments for examination of pavement condition and below-ground variations such as lowerings and developing pot-holes. 3D point clouds captur...
Change detection is an essential step to locate the area where an old model should be updated. With high density and accuracy, LiDAR data is often used to create a 3D city model. However, updating LiD...
These studies have been conductedusing non-metric digital camera and dense image matching algorithms, as non-contact methods of creating monuments documentation.In order toprocess the imagery, few ope...
We present an approach to convert a small portion of a light field with extracted depth information into a cinematic effect with simulated, smooth camera motion that exhibits a sense of 3D parallax....
Light Detection and Ranging (LIDAR) is a technology used for collecting topographic data. Nowadays there are diverse application areas of LIDAR data that include DTM generation and building extraction...
Intense competitions in computer related industries have lead to the development of new amazing technologies. This drastically improved 3D game engine, which was initially developed for computer games...
Displaying large-scale 3D vector data in landscape map is very important, as 3D vector data can provide many important information, such as: precise geographic boundaries, areas, 3D text marks, differ...
3D models of buildings are useful for many applications such as urban planning and environmental simulation, cartography, tourism and mobile navigation. Automatically generating building models in the...
For achieving high-quality LIDARgrammetry and performing surface reconstruction by 3D point clouds acquired at different locations or in different coordinate systems, a novel method was proposed and i...
The study highlights a novel method to segment single trees in 3D from dense airborne full waveform LIDAR data using the normalized cut segmentation. The key idea is to subdivide the tree area in a vo...
