Two-dimensional-image-based 3D (three-dimensional) printing system and method

Abstract

The invention discloses a two-dimensional-image-based 3D (three-dimensional) printing system and a two-dimensional-image-based 3D printing method. The system comprises a 3D automatic reconstruction module, a 3D printing data automatic processing and exchange interface module and a 3D printer. The method comprises the following steps of first placing two cameras at different positions to shoot two images of the same scene or placing a camera to shoot the two images of the same scene in a moving or rotating way to obtain an image pair; then extracting characteristic information from the image pair by using the system; next establishing a corresponding relationship between the characteristic information of the two images in the image pair according to the calculation of the characteristic information by using the system, and matching a physical point of the same control to correspond to mapping points in different images; finally performing depth calculation on a matched and corresponding imaging model according to a geometric relationship between a time lag and a depth in the imaging model by using the system. According to the system and the method, the labor cost and the time cost are greatly lowered; moreover, the method is easy to implement, and the system is low in cost and consistent with the trend of development of 3D printing in the future.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a two-dimensional image-based three-dimensional printing system and method. Background technique [0002] Today, when design activities and design results are flooding every link and field of people's lives, the purpose of design has shifted from the realization of functions to the realization of artistic, emotional and experiential lifestyles, and design activities have become popular activities. The standardized market in the past has begun to change. The demand for personalized and customized products and services will inevitably become a trend, and mass industrial production will withdraw from certain fields. Provide personalized and customized products and services so that consumers can better understand their needs. [0003] In the past, the product design and development cycle was relatively long, involving many factors such as product cost input, limitat...
