In one embodiment of the invention, the infrared sensors with different wavelengths are adopted to form the energy gradient perception of the infrared radiation of the object. The resolution of the infrared focal plane array can reach 640x480 (long wave) and 2048x2048 (short wave) at present.

Meanwhile, the heat distribution packaging data can also comprise a determined distance from an infrared background formed by the fixed radiator to the infrared focal plane array 01, a detection area of the infrared focal plane array 01, a parameter set of the infrared focal plane array 01 and the like.

There are a number of sophisticated encoders and packaged integrated circuits in the prior art that require only input data to be determined to form determined packaged data (e.g., distributed packaged data in the thermal dimension formed by the present invention).
And the data conversion device 03 is used for performing graphic coding conversion on the heat distribution packaging data to form pattern data.
Those skilled in the art will appreciate that the data magnitude may be converted to a color representation in a particular color space or a graphical representation in a particular graphical space based on the definition of the data meaning, the determination of the data dimension.
