Embodiment Construction

[0022] The present invention will be described in further detail below with reference to the drawings and preferred embodiments.

[0023] (1) Perform grayscale processing on the reference light source image, then the reference light source grayscale value f base = 35 corresponds to the intensity value L base = 95000lx;

[0024] (2) Framing the muzzle flash video of the propellant charge and transform it into an image sequence for gray-scale processing;

[0025] (3) Perform image segmentation on the muzzle flash image sequence, and separate the muzzle flash from the background. The white area in the segmented image is the flash image and the black area is the background, such as figure 1 Shown

[0026] (4) The intensity value of any pixel in m×n muzzle flash area:

[0027]

[0028] (5) Calculate the average value of all pixels in m×n muzzle flash area to obtain the average intensity value of a single muzzle flash image:

[0029]

[0030] The specific calculation results are as follows: ...

Abstract

The invention discloses a propellant charge muzzle flash intensity video image processing method. The method is mainly suitable for the visible light band video image processing of propellant charge muzzle flash. The method is mainly characterized by converting a muzzle flash video into an image sequence; carrying out grayscale processing on an image; and using a grayscale difference between the image sequence and a reference light source image to calculate the average intensity of the muzzle flash through image processing. By using the method, the measured quantification evaluation problem ofpropellant charge muzzle flash intensity is solved, and a new breakthrough in a muzzle flash characteristic measurement technology is realized.

Description

Technical field [0001] The invention relates to a video image processing method, which is suitable for video image processing of the muzzle flash intensity of a firing charge. Background technique [0002] Muzzle flash is the general term for primary flame, intermediate flame and secondary flame after the propellant combustion product of the barrel weapon is fired out of the muzzle. The strong muzzle flash can cause the operator to blind for a short time and affect the re-targeting and shooting. It can also cause the guidance system to produce strong interference and fail to track the target, and it is easy to expose its position and be attacked by the enemy. [0003] At present, the main methods for testing muzzle flash intensity include bulb photography, drum photography, and spectral temperature measurement. The camera Bulb method captures the cumulative photos of the flashes of the muzzle flash during its duration, and qualitatively analyzes the strength of the flashes from th...
