Background
In the case of temperature measurement by an infrared thermal imager, because the display resolution of infrared thermal imaging is low (the image resolution of current mainstream thermal imaging equipment is 384 × 288, the infrared image resolution is 11 ten thousand pixels, and the image resolution of visible light is already on the order of million pixels), in practical application, because the thermal imaging resolution is low, it is difficult to confirm the specific position of a temperature anomaly point in a positioning picture through a thermal imaging picture. The temperature data obtained by thermal imaging and the image data obtained by a visible light camera are complementarily combined.
The pictures captured by the temperature detection early warning system are captured from the real-time video stream, and the captured pictures can only display the temperature information superposed on the video stream during capturing, but cannot perform temperature analysis on the stored pictures. Only the area and the temperature of the image captured by the system can be seen; the temperature conditions of other places where the detection area is not drawn cannot be known.
Moreover, the processing of the pictures is usually performed by sequentially transmitting the pictures upwards from the bottom monitoring center and then controlling the pictures by each monitoring center, wherein the upper monitoring center is limited by the reported data of the lower monitoring center and cannot ensure the integrity and reliability of the data. Moreover, the existing uploading mode is generally the uploading through the unique communication mode, and if the current communication mode is unstable, the data loss is easily caused; the above process may also cause inconsistency of data in data centers at different levels, thereby causing inconsistency of exception handling, resulting in generation of contradiction.
