Description
Technical Field
[0001] This utility model relates to the field of measurement device technology, and in particular to a triangulation measurement device for three-dimensional reconstruction of images. Background Technology
[0002] With the development of science and technology, image processing and 3D reconstruction technologies have also seen tremendous growth and application. As a type of image processing technology, 3D reconstruction technology can be used to create 3D models of objects to better understand and analyze the characteristics and attributes of real objects, as well as its applications in many fields. In art education, this technology can be used to convert 2D artworks into 3D models, allowing students to appreciate the works from different angles, analyze light and shadow and three-dimensionality, and improve their art appreciation and creative abilities. In product design teaching, design sketches or images can be reconstructed into 3D models, enabling students to quickly present their design ideas, conduct virtual demonstrations and evaluations, and promote design innovation and the cultivation of practical skills.
[0003] Current methods for 3D reconstruction of images require triangulation by placing a camera scanning device at multiple corners of the object, calculating 3D coordinates in a 3D coordinate system, and then connecting these points to create a 3D model. However, the current method of placing the camera scanning device involves manual placement of the triangulation points, which may lead to deviations that affect the details of the 3D model. Furthermore, the position of the camera scanning device cannot be adjusted in real time while scanning the object.
[0004] Therefore, it is necessary to provide a new triangulation device for three-dimensional reconstruction of images to solve the above-mentioned technical problems. Utility Model Content

[0019] 1. This utility model allows items that need to be reconstructed in three dimensions to be placed on a set placement tray. When a specific item needs to be reconstructed in three dimensions, the item can be manually placed on the placement tray inside the frame. During the three-dimensional reconstruction, the upper output end of the rotary motor is rotated by manually operating the controller, which drives the placement tray fixedly connected to the output end to rotate, thereby facilitating the complete scanning of the item by the camera scanning device.
[0020] 2. This utility model allows for the placement and adjustment of the camera scanning device using a set mounting frame. Before 3D reconstruction, the camera scanning device can be manually placed on the mounting frame. By manually rotating the rotating handle, the threaded rod inside the rotating handle engages with the threaded hole and rotates, causing the clamp plate fixedly connected to the inner end of the threaded rod to press inward, thus clamping and fixing the camera scanning device placed on the mounting frame in an alternating manner. The mounting frame can be moved by manually pushing the rod, causing the lower rotating shaft and the slider fixedly connected to the lower end of the mounting frame to slide inside the slide rail, thereby fixing the camera scanning device to the triangular position and adjusting the triangular spacing of the camera scanning device.
