上个周末终于去了世博，继若干年前春运时在上海南站通宵排队买火车票之后，再次被勤劳勇敢的中国人民的排队能力震撼了。人胖，不能久站，只看了若干冷门馆，在此分享一下我在世博会上看到的计算机视觉与增强现实相关玩意儿。
中国馆的清明上河图相当的赞，一副画卷在长廊的墙壁上徐徐展开，粗粗估计一下，至少用了15个投影仪，画中灯光水影，市井里人来人往，客栈里人声鼎沸。有那么一瞬间，我感觉我像是轩辕剑三之天之痕里的正要找个杂货店买些天仙玉露的陈靖仇。。。
cvchina曾经介绍过几款深度摄像头，看这里，但是他们的价格都让人望而却步，不是谁都能承担得起几千美元的设备的。最近得知另一个消费者级别的深度摄像头（感谢某巨专业人士），价格应该在200美元左右，跟快要上市的kinect差不多一个价位。
上海世博会再有50天就开幕了，意大利的VisLab将以一项壮举参与此次世博会：VisLab将用两辆无人驾驶的，主要由太阳能驱动的汽车货车，从意大利罗马长途奔袭到上海！
关于这两辆无人车：
Two electric vehicles will perform a 13,000 km trip mainly powered by solar energy, with no driver; two backup vehicles will be part of the trip as well. As a support, 4 Overland trucks will follow the expedition to provide a mechanic shop, storage, and accommodation; finally two additional trucks will be used for media coverage and will be equipped for live satellite broadcasting.
The first vehicle will drive autonomously in selected sections of the trip and will conduct experimental tests on sensing, decision, and control subsystems, and willcontinuously collect data. Although limited, human interventions will be needed to define the route and intervene in critical situations.
The second vehicle will automatically follow the route defined by the preceding vehicle, requiring no human intervention (100% autonomous). This will be regarded as a readily exploitable vehicle, able to move on predefined routes; at the end of the trip, its technology will be transferred to a set of vehicles to move in the inner part of Rome in the close future.
During the trip, demonstrations will be performed in specific hot spots; autonomous vehicles will follow given routes, negotiating traffic, avoiding obstacles, and stopping when required. The first demonstration was held in Rome at the EUR district on October 29, 2009, when Rome’s Major, Gianni Alemanno, officially presented this challenge. More information on the presentation can be found in the official press release.
关于VisLab：
The Artificial Vision and Intelligent Systems Laboratory (VisLab) of Parma University (Italy) is involved in basic and applied research developing machine vision algorithms and intelligent systems for the automotive field.
It undertakes research in many disciplines like machine vision, pattern recognition, low-level image processing, machine learning, artificial intelligence, robotics, and real-time systems, but the main focus of the laboratory is to apply basic and advanced research to intelligent transportation systems and intelligent vehicles.
The laboratory know-how is world renown and was mainly developed together with automotive companies for active/passive safety systems,Advanced Driver Assistance Systems,perception of the automotive environment, up tocompletely automatic vehicle driving. Some examples are: lane detection, vehicle detection, pedestrian detection, obstacle localization, sensor fusion with radar and laserscanner, night vision, start inhibit. The know-how includes: monocular, stereo, trinocular, up to tetra-vision systems, using daylight, Near Infrared, Far Infrared cameras; analog and digital cameras. You may download a brochure describing VisLab’s main experiences.
