Method for inhibiting atmospheric scattered light in laser active fog-penetrating imaging

The invention discloses a method for inhibiting atmospheric scattered light in laser active fog-penetrating imaging, and relates to the technical field of laser imaging, and the method comprises the following steps: separately placing a laser light source and a CCD image sensor; calculating the relationship between the atmospheric scattered light energy received by the CCD under different conditions and the discrete distance L; calculating target energy received by the CCD under different conditions; calculating the signal-to-noise ratio SNR of the image according to the atmospheric scattered light energy and the target energy, and obtaining the discrete distance LSNR = 1 when SNR = 1 according to the relationship between the atmospheric scattered light energy and the discrete distance L; setting a discrete distance Lgt; lSNR is equal to 1, so that inhibition of atmospheric scattered light in laser active fog-penetrating imaging is realized under the specific condition.
