Embodiment 1

[0030] refer to figure 1 and figure 2 , a biscuit detection device based on machine vision, used for the detection of biscuits, can realize the integrity and burnt detection of biscuits through visual inspection. The biscuit detection device includes a frame 1, a visual detection mechanism 2 and a lighting mechanism 3. The frame 1 is the installation and fixing structure of the detection device. The biscuit detection device can be installed on the outside of the biscuit production line through the frame. The fixing piece 11 is screwed and fixed on the outside of the biscuit production line. Simultaneously, the visual detection mechanism 2 and the light mechanism 3 are also arranged on the frame, the visual detection mechanism 2 is arranged at the middle position of the top of the frame 1, and the camera assembly 21 of the visual detection mechanism 2 is set downwards, and the biscuit can be photographed downwards Biscuits on the production line; the camera assembly 21 inclu...

Embodiment 2

[0041] A biscuit detection method using the biscuit detection device in Embodiment 1. During detection, the biscuit detection device is set above the biscuit production line, the light mechanism 3 illuminates the biscuit products on the lower production line, and the visual detection mechanism 2 takes pictures of the biscuit products on the lower biscuit production line product. The biscuit detection method includes the following steps:

[0042] S1. Pixel accuracy calibration. The visual inspection mechanism 2 is an industrial camera. Positioning blocks are placed on the biscuit production line under the visual inspection mechanism 2. The position information of the positioning blocks is collected by using the industrial camera for multiple times, and the physical coordinate difference of the positioning blocks is calculated through the processing components. At the same time, the average value of the pixel coordinate difference of the positioning block in the image is calcula...

Abstract

The invention discloses a biscuit detection device and a biscuit detection method based on machine vision. The biscuit detection device comprises a frame, a visual detection mechanism and lighting mechanisms, the visual detection mechanism is arranged in the middle of the top of the frame and shoots biscuits downwards, and the light mechanisms are arranged on the two sides of the top of the frameand project light downwards. According to the biscuit detection method using the biscuit detection device, during detection, the biscuit detection device is arranged above a biscuit production line, the lighting mechanisms illuminate biscuit products on the lower production line, and the visual detection mechanism shoots biscuit products on the lower biscuit production line. The device is used forbiscuit detection, and biscuit integrity and coking detection can be achieved through visual detection.

Description

technical field [0001] The invention relates to the technical field of biscuit processing and production, in particular to a machine vision-based biscuit detection device and a biscuit detection method. Background technique [0002] The biscuit production process usually includes kneading, molding, baking, oil spraying and cooling. Improper control of process parameters can easily make biscuits brittle and coke, which in turn affects the quality of biscuit products. As consumers increasingly demand product quality, it is necessary to inspect the integrity and burnt of biscuits. Traditional biscuit detection mainly adopts the method of manual naked eye detection, which has the disadvantages of high labor intensity, low production efficiency, high missed detection rate and false detection rate. Contents of the invention [0003] The technical problem solved by the invention is to provide a machine vision-based biscuit detection device and a biscuit detection method that can...
