还是车牌识别问题，有从事这行的么？

sam_jiang 发布于 2023-08-29 12:25， 863 次点击
最近需要做个小工程，给充电桩安装一个自动识别车牌的系统，凡是新能源车停靠，就放下地锁，燃油车过来则升起地锁，防止燃油车站位。

社群里有没有从事监控安防工作的？可以帮忙解释一下吗？是自己用，淘了个二手的摄像头，还有2个遥控地锁，没有说明书，一切靠摸索。

你逻辑就有问题，凡是新能源车停靠，就放下地锁，燃油车过来则升起地锁，防止燃油车站位,人家都不按你规则玩，你又如何。。。。。？过闸那是没有办法只有这这条路这个位置

过闸跟升锁是一个道理，只不过闸改成升锁。。。

应该要这样，不是新能源车，停到这个位置，就升锁,把你锁死，你车技好跳锁就警报，是新能源车WX支付成功就降锁走人。。。。。这个研发起来也很麻烦！首先有几个方面的技术架框要搞！回调支付成功要搞吧！你这个没有说明书要估计 哪几个孔接是锁开关，这个控制源码也要搞，还要车牌识别一套下来都要源码开发！这工作量就挺大的。。。。，你不如找个硬件商直接拿它的SDK，开发不是容易些。。。。

那相当于停车收费了，小区已经收过费了，我是要管理充电车位，否则燃油车占位，新能源车没法充电。。。

可问题你有这么多逻辑在里面呀！

直接用海康威识别摄像头，或使用文通摄像头

您的方法也行，楼主的方法也没错，依我看还更好些，不让非新能源车停进来，而不是不让非新能源车开走。

实际你操作一下明白了！逻辑看前者更好！实际有些人,简真就是有点空都要占。。。。

相机的jdk中有车牌识别回调函数，通常会返回车牌号、车牌颜色等信息，还有控制继电器的函数。

没有说明书，有没有类似的资料？

通过ie浏览器脸上摄像机，界面如图：

查看网页的源代码有用吗？
哪里可以查看js源码？

好像是华为的。RG荣耀系列车牌识别摄像机，型号RG-CPY-D，用的好像是海思芯片。

从相机里下载了相机ocx控件，另外也下载了8段js源码，明天再研究一下，谢谢你的sdk手册，太感谢了！！！

据从业者说，摄像头行业的代码都是你抄我，我抄你的，所以你给的sdk会非常有用！

再次感谢

可以从文件名判别是哪个品牌的摄像机吗？
