海康威视热成像实时测温java - 23版

在20年写了一篇实时测温demo博客，看来帮了不少人。今天刚好又有需求，需要采温。也碰到了不少问题，特此记录

1、环境

摄像头：海康 型号：DS-2TD2528T-7/Q  序列：EA0406775

服务器：winServer 

JDK8

2、调试

之前写的demo下载下来。

先把lib 放在D盘下，这边的lib仅限于win64的，如果是其他平台。

海康官网平台下载

后续把账号密码一改，直接发布试一下。

结果

排查故障

询问海康

配置开启功能

登录之后，配置

有些用户会发现，没有本地这一项，那么请看下图。下载插件，刷新即可。

等我配置好之后，重启之后还是code11。静下心来，自己研究程序。

应该是哪里传值不对。

海康的人让我下载Demo看下，其实就是他们的一个测试exe。间接了解海康测温原理，抓图分析。这个工具可以很明显是摄像头没有配置好，还是程序有问题。

这边可以看到，是程序自己没有配置好。

开始琢磨。byRuleID 规则ID是1，我不是很明白 ，dwChan通道ID 是2没有问题。

最后查看相关文档，规则ID 普通模式下只能是0。专家模式下如果只获取对应ID的温度就输入对应规则ID。看图

普通模式和专家模式是互斥的。

最后程序调整下。成功了

3、上代码
