  抱歉，暂时没有demo。 1. setThermalSpotMeteringTargetPoint后，温度从setThermalTemperatureCallback中获取。setThermalSpotMeteringTargetPoint设置的点X和Y的取值范围是0到1，从左上角开始，定义地是屏幕上的点。 2. setThermalMeteringArea后，温度从setThermalAreaTemperatureAggregationsCallback中获取。setThermalMeteringArea设置的矩形，定义可以看下这个链接，https://blog.csdn.net/u013290250/article/details/54926669
