For many computer vision problems, the most time consuming component consists of nearest neighbor matching in high-dimensional spaces. There are no known exact algorithms for solving these high-dimensional problems that are faster than linear search. Approximate algorithms are known to provide large speedups with only minor loss in accuracy, but many such algorithms have been published with only minimal guidance on selecting an algorithm and its parameters for any given problem. In this paper, we describe a system that answers the question, “What is the fastest approximate nearest-neighbor algorithm for my data? ” Our system will take any given dataset and desired degree of precision and use these to automatically determine the best algorithm and parameter values. We also describe a new algorithm that applies priority search on hierarchical k-means trees, which we have found to provide the best known performance on many datasets. After testing a range of alternatives, we have found that multiple randomized k-d trees provide the best performance for other datasets. We are releasing public domain code that implements these approaches. This library provides about one order of magnitude improvement in query time over the best previously available software and provides fully automated parameter selection.

机器人轨迹生成经典书籍 This book deals with the problems related to planning motion laws and trajectories for the actuation system of automatic machines, in particular for those based on electric drives, and robots. The problem of planning suitable trajectories is relevant not only for the proper use of these machines, in order to avoid undesired effects such as vibrations or even damages on the mechanical structure, but also in some phases of their design and in the choice and sizing of the actuators. This is particularly true now that the concept of “electronic cams” has replaced, in the design of automatic machines, the classical approach based on “mechanical cams”. The choice of a particular trajectory has direct and relevant implications on several aspects of the design and use of an automatic machine, like the dimensioning of the actuators and of the reduction gears, the vibrations and efforts generated on the machine and on the load, the tracking errors during the motion execution. For these reasons, in order to understand and appreciate the peculiarities of the different techniques available for trajectory planning, besides the mathematical aspects of their implementation also a detailed analysis in the time and frequency domains, a comparison of their main properties under different points of view, and general considerations related to their practical use are reported.

自动驾驶仪对有人和无人驾驶飞机的重要性是不言而喻的,近年来随着美国和以色列等国家在局部战争中大量使用无人机,而引发了国际和国内无人机研制的热潮。无人机飞行的基础是用自动驾驶仪实现的自动飞行控制系统,而飞行力学和自动控制技术则是理论基础,它们通常对应不同的专业,飞行动力学和飞行控制方面曾分别出版过一些专著和参考书。本书的作者尼尔森教授在本科和攻读硕士期间专业是飞行动力 学,而在Pennsylvania大学读航天工程博士学位则是研究飞行自动控制,后来又在美国空军的飞行动力学试验室担任工程师,负责一种轰炸机机载短距离空空防卫导弹开发,因此他对于这两个学科都有很高的造诣,而在研发导弹中的一些实际工程经验也在这本书中体现出来。本书的特点就在于它把飞机的飞行力学、飞行自动控制和自动驾驶仪设计的整个过程系统综合在一起,而又相当简练,体现出了一种工程实用性。
