摘要：This paper presents a new Omni-Directional Tilt Sensor (ODTS), which consists of the LED light, transparent cone-shaped closed container, mercury, camera, embedded systems and so on. The volume of the mercury in the container is equal to half of the container’s. When the detected surface is horizontal, the shape of mercury in the image captured by the camera is a black disc since the mercury is lightproof. When the detected surface tilts, the mercury flows and the mercury surface always maintains horizontally due to the gravity force of the earth. At this time, some area of the transparent cone-shaped closed container is not shaded by mercury and the border of the mercury’s shape in the captured image is a half circle and a half ellipse. Thus there is a translucent crescent-shaped area in the image. With analyzing this area by the specific algorithm based on machine vision, the tilt angle and directional angle can be obtained. The experimental results show that the ODTS proposed has some advantages, such as simple maintenance, high precision, wide range, low cost, real-time, reliability and high visualization.

摘要：After the analysis of the beauty contained in motion vision, the paper had pointed out that motion vision was the link for spectators relating and communicating with aesthetic objects and decided landscape space construction sequence. It further analyzed the relations between architectural space and visual perception which could be divided into inner experience and external experience. By taking landscape space construction of Sichuan Olympic Sports School for example, based on the analysis of design principles and objective of landscape space, the paper had focused on the discussion of landscape concept in terms of motion vision. In the perspective of two-dimensional vision, landscape effects of White Pigeon Square and Bright Eyes Square had been introduced. In the perspective of three-dimensional vision, landscape effects of the Olympic Rings waterscape and the Olympic Rings gallery had been illustrated. Finally, based on the integration between landscapes and architectures under visual perception, the coordination between campus architectures and landscape construction in Olympic Sports School had been analyzed.

摘要：现有的深度哈希图像检索方法主要采用卷积神经网络,提取的深度特征的相似性表征能力不足.此外,三元组深度哈希主要从小批量数据中构建局部三元组样本,样本数量较少,数据分布缺失全局性,使网络训练不够充分且收敛困难.针对上述问题,文中提出基于类相似特征扩充与中心三元组损失的哈希图像检索模型(Hash Image Retrieval Based on Category Similarity Feature Expansion and Center Triplet Loss,HRFT-Net).设计基于vision Transformer的哈希特征提取模块(Hash Feature Extraction Module Based on vision Transformer,HViT),利用vision Transformer提取表征能力更强的全局特征信息.为了扩充小批量训练样本的数据量,提出基于类约束的相似特征扩充模块(Similar Feature Expansion Based on Category Constraint,SFEC),利用同类样本间的相似性生成新特征,丰富三元组训练样本.为了增强三元组损失的全局性,提出基于Hadamard的中心三元组损失函数(Central Triplet Loss Function Based on Hadamard,CTLH),利用Hadamard为每个类建立全局哈希中心约束,通过增添局部约束与全局中心约束的中心三元组加速网络的学习和收敛,提高图像检索的精度.在CIFAR10、NUS-WIDE数据集上的实验表明,HRFT-Net在不同长度比特位哈希码检索上的平均精度均值较优,由此验证HRFT-Net的有效性.
