[0025] Embodiment

[0026] As Figure 1 Indicated, a kind of online visual identification detection device based on single-chip microcontroller, including detection table 1, lifting seat 2, rotating seat 3, detection frame 4, digital camera 5 and single-chip microcontroller.

[0027] Wherein detection table 1 surface is provided with accomodate the groove 11, lifting seat 2 is installed in accomodate the groove 11 by pneumatic cylinder;It can be moved up and down by pneumatic cylinder to drive lifting seat 2, to drive rotating seat 3 and the article placed on it moves, changes its distance with digital camera 5, to facilitate digital camera 5 to obtain more clear picture, to carry out visual identification, guarantee the accuracy of identification result.

[0028] Rotary motor is inlaid in lifting seat 2, and the output end of rotary motor is fixedly connected with rotating seat 3;Rotating seat 3 and the article placed on it can be rotated by rotary motor;Again cooperation through servo motor installation detection frame 4 in install the frame 12, by tilting detection frame 4 and cooperating with rotating seat 3, can be photographed on different angles on side surface, obtains more angle, more state under the article picture, can carry out comprehensive detection to each side of product, effectively avoid the defect missed detection problem caused by single detection angle, greatly improve the comprehensiveness and accuracy of detection.

[0029] After receiving the image data captured by the digital camera 5, the single-chip microcomputer stores it in its internal memory (such as RAM). The single-chip microcomputer runs specific image processing algorithms to analyze the image. These algorithms include image filtering, edge detection, feature extraction, and object recognition, etc.

[0030] Among them, image filtering is used to remove noise in the image, such as Gaussian filtering. It calculates the weighted average of each pixel and its surrounding pixels in the image, making the image smoother and reducing the impact of noise on subsequent processing.

[0031] Edge detection: Determine the edges of objects by calculating the gradient changes of pixels in the image. For example, the Sobel operator detects edges by calculating the gradients in the horizontal and vertical directions. It can help identify the contours of objects, providing a basis for further shape analysis and recognition.

[0032] Feature extraction: Extract representative features from the image. For example, for object recognition, shape features (such as circularity, rectangularity), color features (such as color histogram), or texture features (such as gray level co-occurrence matrix) may be extracted. These features can more effectively describe the object, facilitating subsequent classification and recognition.

[0033] Target recognition: According to the extracted features, the single-chip microcomputer uses pattern recognition algorithms for target recognition. For example, a template matching algorithm can be used to compare the extracted features with pre-stored standard template features. If the similarity exceeds a certain threshold, the target is considered to be recognized. Or use machine learning algorithms such as support vector machines (SVM) or artificial neural networks (such as simple multilayer perceptron), through training models to recognize targets. These models learn the feature patterns of different targets in the training phase, and can classify according to the input image features in the recognition phase.

[0034] The single-chip microcomputer can also control the cylinder, rotary motor, servo motor by generating signals, so as to adjust the state of the lifting seat 2, rotating seat 3, detection frame 4, make it lift or rotate, to meet the requirements of the digital camera 5 in different angle state of picture shooting.

[0035] Please refer to Figure 2, the detection platform 1, the lifting seat 2 and the rotating seat 3 are concentric circular structures, and the concentric structure has symmetry, which is beneficial to ensure that the detection conditions of the detection object in each direction are consistent in visual detection. When the rotating seat 3 rotates, the rotation with the center as the center can ensure that each angle of the detection object can be shot by the digital camera 5 at the same distance and angle in theory, which reduces the error caused by different detection positions and is beneficial to realize more accurate appearance detection and size measurement and other operations. The mounting frame 12 is located on the diameter of the circular structure of the detection platform 1, and this layout is beneficial to optimize the detection range and angle. The detection frame 4 is installed on the mounting frame 12 located on the diameter, and the moving range thereof can cover most of the area of the detection platform 1, and in combination with the rotating function of the rotating seat 3, the visual detection of the detection object in all directions and without dead angle can be realized. At the same time, this layout can make the digital camera 5 obtain more suitable light reflection and image view angle at different positions and angles, thereby improving the quality and efficiency of visual identification.

[0036] The detection frame 4 has an inverted U-shaped structure as a whole, the middle part is provided as a horizontal section, the two ends are provided as vertical sections, and the vertical sections are connected with the horizontal section through inclined sections; this shape can ensure that the digital camera 5 has enough space to adjust the position in the horizontal and vertical directions, thereby realizing visual coverage of the detection object in all directions. The middle position of the horizontal section enables the digital camera 5 to vertically downwardly shoot the central area of the detection object. This vertical shooting angle is beneficial to reduce the deformation of the image, and in particular when detecting an object with a regular geometric shape, the size and shape characteristics thereof can be more accurately measured.

[0037] The semicircular structure is provided at the two ends of the detection frame 4 and is provided with uniformly distributed limiting holes 41, and the limiting pin 13 driven by the electric push rod is provided on the detection platform 1, and the main purpose is to realize accurate positioning of the detection frame 4. When the detection frame 4 needs to stop at a specific position, the single-chip microcomputer controls the electric push rod to push the limiting pin 13 to insert into the limiting hole 41, and this mechanical connection mode can ensure that the position accuracy of the detection frame 4 in the horizontal direction reaches a high level. For example, when some specific parts of the detection object are subjected to high-precision visual detection, accurate positioning can ensure that the digital camera 5 can shoot the part at the same position and angle each time, thereby improving the consistency and accuracy of the detection result. And the plug-in cooperation of the limiting pin 13 and the limiting hole 41 can enhance the stability of the detection frame 4 when it is used obliquely.

[0038] The rotating seat 3 is provided with a ring-shaped protective pad 31, which can play a certain buffering protection role when larger objects are placed, so as to avoid rigid contact between the object and the rotating seat 3; the triangular indicating mark 32 is provided for the purpose of indication, which is used as a reference standard to correspond to objects in different states.

[0039] AsFigure 3 , Figure 4 As shown in FIGS. 1-3, the device is in different use states, respectively; wherein Figure 3 FIG. 1 is a use state of the device when the detection frame 4 is tilted and photographed, Figure 4 FIG. 2 is a use state of the device after the lifting seat 2 is lifted and the rotating seat 3 is rotated.

[0040] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the present application, and these modifications and changes should be within the protection scope of the present application.
