Problems solved by technology
[0003] Manual quality inspection method will produce detection errors due to long-term work fatigue and responsibility problems
The detection method of automatic weighing, due to the influence of the instrument accuracy of the detection system itself, there are more or less certain measurement errors, and the labor cost is high, and the calculation has insufficient errors, which brings certain losses to the company's benefits.
[0004] In order to overcome the shortcomings of high labor costs and calculation errors in the original traditional detection method, the present invention provides a method for detecting damaged biscuits based on image processing

Embodiment Construction
[0035] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0036] Such as figure 1 As shown, the image processing-based biscuit damage detection device of the present invention includes an industrial camera and an industrial computer; the industrial camera is installed above the operation line before the biscuit is bagged, and the industrial computer receives and analyzes image information.
[0037] Such as Figure 2 to Figure 8 As shown, the biscuit damage detection method based on image processing of the present invention comprises the following steps:
[0038] (1) Collect real-time biscuit graphs on the production line;
[0039] (2) Preprocessing the collected images;
[0040] As shown in Figures 5(a) to 5(e), the preprocessing includes graying the collected images, adaptive threshold segmentation, and vertical projection; the discretized projection image is equalized for the discrete projection i...

The invention discloses a biscuit damage detection device based on image processing and a detection method thereof. The device includes an industrial camera and an industrial control computer; the industrial camera is installed above the operation line before the biscuit is bagged, and the industrial control computer receives and analyzes the image information . The method includes collecting real-time biscuit images on the production line; preprocessing the collected images; performing a non-maximum value suppression operation on the preprocessed images; performing numerical analysis on the maximum value images to determine whether the sequence of positions is equidifferential; the determination is completed and output. The beneficial effect is that the industrial camera collects picture information on the assembly line in real time, and analyzes and calculates the information through the industrial computer to accurately detect defective biscuits. The device has small calculation process errors, fast detection speed, and low maintenance costs. Accurate judgment.
Description
technical field [0001] The invention relates to a damage detection method, in particular to an automatic detection device and a detection method for product defects in a biscuit production line. Background technique [0002] For food production enterprises, especially pastry and biscuit production enterprises, real-time monitoring and statistics of product quality is an important task. The existing traditional detection methods include: manual identification method, automatic weighing method and so on. [0003] The manual quality inspection method will cause detection errors due to long-term work fatigue and responsibility problems. The detection method of automatic weighing, due to the influence of the instrument accuracy of the detection system itself, has more or less certain measurement errors, and the high labor cost and insufficient calculation errors have brought certain losses to the company's benefits. [0004] In order to overcome the shortcomings of high labor co...
