Embodiment Construction
[0028] The specific steps of the infrared image enhancement method according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0029] Usually the image data obtained from the infrared detector is an N-bit binary value. In order to be able to display the infrared image data, it is necessary to convert the image data from the N-bit binary to the value range for display (usually the range is 0 to 255). This transformation is usually achieved with a grayscale linear stretching method. The gray scale linear stretching method provides a linear calculation formula to map the image data to the display value range. The specific conversion process can be as follows figure 1 shown.
[0030] figure 1 The middle r axis represents the image data acquired by the detector before transformation, and the minimum value of the image data is r min , with a maximum value of r max . The S axis represents the transformed ...
