Description

Technical Field

[0001] The utility model relates to the field of image acquisition, in particular to an image acquisition auxiliary mobile frame for model training. Background Art

[0002] Artificial intelligence (AI) is a discipline that studies how computers can simulate and display human intelligence, endowing them with human-like capabilities, such as learning, reasoning, and problem-solving. Through algorithms and models, AI can learn patterns from large amounts of data and apply them to new situations. Computer vision is a major branch of AI. Existing techniques typically use cameras to capture large amounts of static and dynamic images as training data, ensuring both data diversity and representativeness. Objects or features in each photo are then precisely labeled and pre-processed. An appropriate model is selected and trained using the large amount of collected image data. The labeled information and recognition results are then compared and feedback is provided. The algorithm model is continuously revised to improve image recognition speed and accuracy.

[0003] In order to improve the recognition speed and recognition rate of specific targets, it is usually necessary to collect a large number of pictures of the target at different angles and distances and perform preliminary annotation. The traditional method is to use a handheld camera to take multiple groups of photos of different angles in sequence. However, manual shooting is not only labor-intensive but also has a large randomness in position, which is not conducive to accurately annotating position and angle information. Later comparison and feedback are difficult, which is not conducive to the rapid correction of image recognition algorithm models. Utility Model Content

[0018] The object to be photographed is placed at the center of the first curved track rod 101 and the second curved track rod 102. The mobile platform 2 moves from one end of the base frame 1 to the other end to collect dynamic images. If collecting static photos, it stops and takes photos at a set distance to obtain photos of the object from different angles for visual training.

[0019] The angle between the first curved track rod 101 and the second curved track rod 102 is greater than ninety degrees, and at least two images in an orthogonal direction can be captured.

[0020] After shooting in one direction, you can adjust the object to rotate at a certain angle and continue to capture the next set of images.

The walking drive motor 6 drives the worm 601 to rotate, and the worm 601 drives the worm gear 602 to rotate and slow down. The gear 606 is driven by the synchronous belt assembly to walk on the arc rack 103, and finally drives the mobile platform 2 to move in an arc.

[0025] A control cabinet is arranged on one side to control the motor movement and camera shooting, and transmit the captured images to the memory for storage in a timely manner.

[0026] In the preferred solution, the camera bracket 3 includes a base 301, a vertical pole 302 is provided on the base 301, a first pole clamp 303 is provided at the upper end of the vertical pole 302, and a transverse pole 304 is also provided.

[0029] The front side of the lighting lamp 5 emits light, and the front lens group of the industrial camera 4 is located behind the central axis of the lighting lamp 5, so the light source will not directly enter the industrial camera 4 to generate glare.

[0030] The ring light source increases the illumination area, reduces the concentration of the light source, and reduces the reflected highlights of the photographed object, which is conducive to taking clearer photos.
