Technology Field

[0001] The present invention relates to an automated image capturing device capable of automatically capturing images of a subject while moving the subject to various angles and positions according to coordinate values ​​set by a user. Background Technology

[0003] In general, image data plays a crucial role in the training and validation processes of AI algorithms, and because this enables recognition and classification tasks with higher accuracy and reliability, machine vision systems require a large amount of high-quality image data.

[0004] However, collecting product images from various conditions and angles in actual industrial settings is not only time-consuming and labor-intensive, but can also sometimes be impossible.

[0005] Furthermore, while existing data augmentation methods can save time and costs, the generated images often do not reflect actual conditions, limiting the model's generalization ability. This leads to overfitting, which can cause the model to produce unexpected errors in real-world environments.

[0006] As such, the data currently used to train AI machine vision models has limitations in terms of diversity and reflection of real-world environments. Since this can act as a major factor in lowering the accuracy and reliability of the models, there is a problem where the quality of the generated models may deteriorate.

[0007] Furthermore, due to the current lack of flexible shooting settings and adjustment functions to respond to various products and environments, there is a problem in that not only is the operational efficiency of training AI machine vision models reduced, but the scope of application of the models is also limited.

[0035] At this time, it is preferable that the rotation axis protrude and be exposed to the bottom surface of the rotation table (100) so that sufficient space for the subject (1) to be placed is secured.

[0036] The above Y-axis movement module (110) is coupled to the lower surface of the rotary table (100) and can operate to move the rotary table (100) in the Y-axis direction.

[0037] For example, the above Y-axis movement module (110) may include a second motor (111) and a Y-axis movement block (114) that moves in the Y-axis direction by the driving force of the second motor (111), as shown in FIGS. 4a and 4b.

[0038] The rotary table (100) is coupled to the Y-axis movement block (114) of the Y-axis movement module (110) and can move in the Y-axis direction according to the operation of the second motor (111).

[0039] At this time, the rotary table (100) may be provided with a fixing means for fixing the placed object (1).

[0040] Although the above fixing means is not shown in the drawing, it is provided at the center of the upper surface of the rotary table (100) and can fix the position of the subject (1) during rotation by the moving part (10) and movement in the X-axis and Y-axis directions.

[0041] These fastening means may be applied by selecting a suitable one from among known fastening means, such as bolt fastening, clips, and clamps.

[0042] It is preferable that the above-mentioned rotating table (100) has a size suitable for the size of the subject (1), as well as the angle of view, focal length, and resolution of the camera unit (30).

[0060] In addition, the control unit (20) can generate a control signal for operating not only the moving unit (10) but also the camera unit (30) described below, and transmit the generated control signal to the camera unit (30).

[0061] The above control unit (20) may be equipped with operating software that allows the administrator terminal (60) to be connected.

[0062] The above operating software can provide a UI (user interface) that allows user settings, various shooting conditions, and movement coordinate values ​​of the subject (1) to be input through a connected administrator terminal (60).

[0066] In addition, the above-mentioned operation module (210) can generate individual control signals that adjust the angle of view and focal length of the camera unit (30) according to shooting conditions input through the above-mentioned input module (200), and individual control signals that adjust the lighting brightness and color temperature of the lighting unit (50).

[0067] The output module (220) can output individual control signals calculated and generated by the calculation module (210) and transmit them to selected devices, namely the moving unit (10), camera unit (30), and lighting unit (50).

[0068] In particular, the control unit (20) may receive physical characteristics including color, texture, and size of the subject (1) through the input module (200), and based on the received physical characteristics, control one or more shooting parameters such as the brightness and color temperature of the lighting by the lighting unit (50), the angle of view or focal length of the camera unit (30), and the movement speed of the moving unit (10) to be automatically adjusted.

[0069] In addition, the control unit (20) further includes a memory (230) so that a plurality of individual shooting parameters pre-set according to the model or type of the subject (1) as well as user settings can be stored.

[0070] And the control unit (20) can load individual shooting parameters corresponding to the model or type from the memory (230) when selecting the model or type of the subject (1) to be photographed, and control one or more of the brightness and color temperature of the lighting by the lighting unit (50), the angle of view or focal length of the camera unit (30), and the movement speed of the moving unit (10) to be automatically adjusted.
