In this paper, the non-contact FARO 3D laser scanning system was used for tree scanning, and the preprocessing of point cloud data as well as its accurate extraction was done in its affiliated software FARO SCENE. In addition, the software GEOMAGIC STUDIO was used to extract the tree measuring factors accurately. By comparison of the error analysis concerning scanning value and measuring value, the...
The study on the bearing capacity and settlement is important to a project. It is useful and concrete to develop a model with some intelligent methods in artificial intelligence area for the prediction of some big structure projects. The validity of the models has been proved by some civil engineering practices. Therefore, the research of bearing capacity and settlement characteristics of rigid pile...
We describe a distributed algorithm for coordinating a swarm of homogeneous robots to explore an unknown area using only local interaction. The basic movement rule is based on the gas dispersion model. To avoid duplication exploring, we introduce a new strategy called SMARK to leave signpost in explored area. Consequently this system have three outstanding features: (1) The swarm of robots coordinate...
In order to assess the `total emission reduction in provincial level', this paper proposes an index system including environment, policy, economy and engineering. And according to the requirement of `veto by one vote', the index weight is decided by analytic hierarchy process and variable weight method, based on which a fuzzy comprehensive evaluation model for emission reduction in provincial level...
A new method is proposed for speckle noise suppression and water objects extracting from synthetic aperture radar (SAR) imagery based on sequential nonlinear filtering and independent component analysis. The distribution of SAR image data with multiplicative speckle noise is non-Gaussian and its parameters are unknown. Logarithmic quantification is utilized to transform multiplicative speckle noise...
In the area of ocean fisheries research, one hotspot is the use of marine environment factors for fisheries forecast. This paper fits in the category using fishery knowledge discovery based on support vector machine (SVM) and fuzzy rule extraction. It takes the Indian ocean big-eye tuna fishery as its testing ground. Firstly, the support vectors are obtained by training the SVM with some sample data...
In a three-dimensional (3-D) model-based objects tracking and recognition system, the key problem of objects location is to establish the relationship between 2-D objects image and 3-D model. Based on 3-D model projection and 2-D image feature extraction, a modified Hausdorff distance is used to establish the matching function. The relationship between matching parameters are described with a probability...
In order to acquire high speed switching in high-speed fiber channel switch network, a method named MRTF (the method of reducing the token's frequency) used to reduce the token's frequency is put up, and the corresponding switch is designed. In this method MRTF, the token is coded with RTFC, the token reducing-frequency code which is a special sequence of `0' and `1' , then it's frequency may be reduced...
Service Oriented Architecture (SOA) and Service Oriented Computing (SOC) are prevailing technologies for sharing and reusing resources. Service composition is an envisioned methodology used in SOA and SOC to build value-added services. The existed service clustering and selection models are mostly designed for service discovery and there is few considering the requirement of service composition from...
