Problems solved by technology

[0002] In order to produce a better discharge effect, the existing fireworks and firecrackers usually fix tens or even hundreds of cartridges into a bundle, but this kind of fireworks and firecrackers is difficult to ensure that the charges in all cartridges meet the standard requirements. During production, it is necessary to arrange specific personnel on each production line to visually inspect each fireworks and firecrackers, and then roughly estimate the charge amount, and determine whether the overall charge amount of fireworks and firecrackers meets the requirements
This manual detection method not only takes a lot of time, reduces production efficiency, and slows down the production process, but also has low detection accuracy, and requires staff to move back and forth for comprehensive observation, consuming a lot of manpower

Embodiment

[0038] The method for image recognition and detection of the charge amount of fireworks and firecrackers in this embodiment, the steps include:

[0039] S1: The fireworks and firecrackers to be detected are photographed and imaged, and each time the fireworks and firecrackers to be detected are photographed and imaged as 10 frames;

[0040] S2: The image data obtained in step S1 is processed to obtain the charge of fireworks to be detected, and the image data processing steps include:

[0041] S21: Perform noise reduction processing on the image data to obtain figure 2 As shown in the clear charge surface curve f, the steps of noise reduction processing include:

[0042] S211: adopt as image 3 The filter template shown performs smooth filtering on the obtained 10 frames of images;

[0043] S212: adopt as Figure 4 The Sobel operator shown performs edge detection and obtains 10 detection results;

[0044] S213: Average the 10 test results to obtain a clear charge surface...

Abstract

The invention discloses a firework and firecracker charge quantity image identification detection method. The method comprises the following steps of shooting and imaging the to-be-detected fireworks and firecrackers, and processing the image data to directly obtain the charge quantity of the to-be-detected fireworks and firecrackers. Compared with manual naked eye detection, the whole detection process is completed by a machine, the detection result is directly obtained, the situation of detection result omission is avoided, and the method has the advantages that the calculation result is accurate and reliable, the detection precision is improved, and convenience and high efficiency are achieved.

Description

technical field [0001] The invention relates to a method for detecting materials, in particular to a method for image recognition and detection of the charge amount of fireworks and firecrackers. Background technique [0002] In order to produce a better discharge effect, the existing fireworks and firecrackers usually fix tens or even hundreds of cartridges into a bundle, but this kind of fireworks and firecrackers is difficult to ensure that the charges in all cartridges meet the standard requirements. During production, it is necessary to arrange specific personnel on each production line to visually inspect each fireworks and firecrackers, and then roughly estimate the charge amount, and determine whether the overall charge amount of fireworks and firecrackers meets the requirements. This manual detection method not only takes a lot of time, reduces production efficiency, and slows down the production process, but also has low detection accuracy, and requires staff to mo...
