Sensor Fusion on Android Devices: A Revolution in Motion Processing
推荐理由
I'm always happy to share this incredible lecture from many many years ago
说明
这是2010年由Google TechTalks发布的一部演讲,主题归在Embedded systems & DIY electronics。它讲的是sensor fusion这一支里的具体问题,而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成:David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.这些读者给出的理由,核心是:HN recommends it as the definitive talk on mobile motion sensing, including why integrating acceleration twice drifts so badly.讲法不绑某一条新闻,过几年仍然可以当材料看。从2012年到2026年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合一次性看完。讲者把一个判断讲透,演示是在给这个判断配例子。如果已经会了基本定义,就把注意力放在它怎么把sensor fusion变成能跟着复述的例子。
