今天逛南京路 在梅陇镇的侧门发展的
应该就是简单测量光线闪烁的装置,不知道能否区分进来还是出去的人流
现在来补上我拍的照片
这个就是发射器和计数器了，在门的对面那个就没有这个读数的部分。
然后有个等人的男子站在正门那里的就把技术器给堵住了。哈哈，计数器就不跳了，有趣啊。

应该没那么简单吧，如果两个人并排走过，不是就漏计了？
技术在发展。GPS+人像自动识别+满城的高清摄像头，行踪无从隐瞒。
据说有提供专业记录客流量硬件和软件的公司，例如ShopperTrak，在室内装修阶段就会埋入设备。
看上去很有意思的东西，真的有效吗？如果那个等人的人不停地在机器面前徘徊？？这个东西的原理是什么？？射线反射回去，然后计数？
