AI Technical Summary

Technical Problem

In existing 3D scanning technologies, the quality of texture mapping is degraded due to the application of markers to the surface of the scanned object, especially when visible light is used as the laser light source, as the laser lines captured on the color image affect the quality of the texture mapping.

Method used

By employing a feature projection strategy and an image acquisition strategy, invisible light band features and laser stripe features are projected onto the surface of the object to be scanned. Combined with image acquisition from grayscale and color cameras, invisible light band features and laser stripes are filtered out. The color camera is triggered to acquire color images in staggered frames to avoid laser stripe interference.

Benefits of technology

It improves the quality of color images, enhances the effect of texture mapping, avoids interference from marker point information and laser lines, and ensures accurate reconstruction of 3D models and high-quality texture mapping.

Abstract

The application relates to a three-dimensional scanning method, device, computer equipment and storage medium. The method comprises the following steps: determining a feature projection strategy and an image acquisition strategy based on a user input scanning instruction; projecting a first feature and a laser stripe feature or projecting the laser stripe feature according to the feature projection strategy; acquiring a grayscale image and a color image of a to-be-scanned object according to the image acquisition strategy; if the laser stripe feature is a visible light wave band, the color image of the to-be-scanned object is acquired and the interval between the projection of the laser stripe feature on the surface of the to-be-scanned object is executed; and three-dimensional reconstruction and texture mapping are performed according to the grayscale image and the color image to obtain a three-dimensional model. No mark points need to be pasted on the surface of the to-be-scanned object, the first feature in the grayscale image is used for splicing, the image acquisition strategy is determined based on the projection strategy during texture mapping, so that the image quality of the color image is ensured, and the quality of the texture mapping is further improved.
