Embodiment 1
[0023] This embodiment discloses a low-slow target positioning and tracking method based on thermal imaging, such as figure 1 shown, including the following steps:
[0024] S01), two photoelectric turntables equipped with thermal imaging cameras are fixed. The two photoelectric turntables can be on the same level or on different levels. Turntable A and photoelectric turntable B. After fixing, record the latitude, longitude and altitude of A and B, and the straight-line distance between A and B. In order to make the rotation angles of the two photoelectric turntables consistent, it is also necessary to calibrate the north of the photoelectric turntable, and calibrate the true north as the zero point.
[0025] S02), digitize the video image collected by the thermal imaging camera of the photoelectric turntable, and for the convenience of processing, the format of the digitized video image is YUV. For monitoring equipment, such as the video captured by the camera, it is digiti...
