A kind of hot spots detection alarm device and method is proposed in the paper about infrared thermal imaging, including the hardware design, algorithm, software realization. The hardware mainly includes the infrared thermal imaging camera and intelligent analysis board; the algorithm uses connected component detection method based on run length to extract target rectangle coordinates. This design uses the simple character overlapping circuit and superimposes the alarm target rectangle on the composite video. It has high integration level, simple circuit, and can effectively deal with more than 12 bit pixel data. Because FPGA uses the parallel processing, greatly improving the graphics processing speed, it is suitable for embedded applications in high real-time.
