Hexagonal grid cylindrical latticed shell structure is proposed, due to honeycomb structure (although the hexagon structure) is the most effective structure on save the building materials. As a result of the shell structure always with numerous bars, the distribution of internal force and the design of bars often rely on many parameters, likes the span of the structure, the rise-span ratio of the structure, the size of mesh etc., the large scaled finite element software ANSYS parametric design language ANSYS Parametric Design Language (APDL) be used to establish the model of hexagonal grid single-layer cylindrical reticulated shell. The optimization design also was done to found whether the model was a feasibility one. The analysis process shows that the parametric design method provides great convenience for the design of the structure.

Reticulated Shell Structure

This paper first used parametric design language APDL to establish three kind of the single hyperbolic paraboloid shell model with rectangular projection. The parametric design of the reticulated shell structure could be realized after inputting the span (S),rise (F),the grid number of each side (Kn),the warping rate (K),which provided great convenience for optimizing the structure and force analysis.Then through contrasting three structure schemes and different warping rate,it studied how they influence the mechanical properties of structure.And at last it got some conclusions with engineering significance.

RGB-D cameras offer both color and depth images of the surrounding environment, making them an attractive option for robotic and vision applications. This work introduces the BRISK_D algorithm, which efficiently combines Features from Accelerated Segment Test (FAST) and Binary Robust Invariant Scalable Keypoints (BRISK) methods. In the BRISK_D algorithm, the keypoints are detected by the FAST algorithm and the location of the keypoint is refined in the scale and the space. The scale factor of the keypoint is directly computed with the depth information of the image. In the experiment, we have made a detailed comparative analysis of the three algorithms SURF, BRISK and BRISK_D from the aspects of scaling, rotation, perspective and blur. The BRISK_D algorithm combines depth information and has good algorithm performance.
