Embodiment Construction

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

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

[0024] (2) Carry out frame division to the flash video of firing charge muzzle, and convert it into an image sequence, and carry out grayscale processing;

[0025] (3) Image segmentation is performed on the muzzle flash image sequence, and the muzzle flash is separated from the background. In the segmented image, the white area 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 the muzzle flash area m×n:

[0027]

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

Abstract

The invention discloses a video image processing method of the flash intensity of the muzzle of a propelling charge, which is mainly suitable for the processing of the visible light band video image of the muzzle flash of the propelling charge. The method mainly converts the muzzle flash video into an image sequence, performs grayscale processing on the image, and uses the grayscale difference between the image sequence and the reference light source image to calculate the average intensity of the muzzle flash through image processing. The method solves the problem of quantitative evaluation of the measurement and evaluation of the muzzle flash intensity of the propellant charge, and realizes a new breakthrough in the measurement technology of the muzzle flash characteristics.

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 firing charge. Background technique [0002] Muzzle flash is the general term for the primary flame, intermediate flame and secondary flame after the propellant combustion product exits the muzzle when the barrel weapon is fired. The strong muzzle flash can blind the operator for a short period of time, affecting the re-aiming and shooting. It can also cause strong interference to the guidance system and make it impossible to track the target. It is also easy to expose its position and be attacked by the enemy. [0003] At present, the methods for testing the muzzle flash intensity mainly include B-door photography, drum photography, and spectral temperature measurement. The camera B door method takes the cumulative photos of the flashes of the muzzle flash within its duration, and qualitatively analyzes the strength ...
