Three-dimensional object model texture mapping algorithm based on mapping boundary optimization

Abstract

The invention discloses a three-dimensional object model texture mapping algorithm based on mapping boundary optimization. The method comprises two steps to optimize a map boundary in the three-dimensional model texture mapping, so that the jointing problems caused by the camera calibration error and other interference factors during the texture mapping is effectively reduced. The method comprises the steps that firstly, the mapping boundary is optimized to reduce the complexity of the texture around the boundary; secondly, the mapping boundary area corresponding to the image edge in two-dimensional images is further optimized, the consistency of the edges, on the two sides of the boundary, of the two-dimensional images is improved, and therefore the effect on the texture mapping from various errors including the camera calibration error can be reduced. According to the three-dimensional object model texture mapping algorithm, the quality of the mapping of the texture around the image edge is improved in an emphasized mode, the boundary area prone to producing a joint is moved to an area with the simple texture, the characteristics of a vision sense system of the human body are met, and the algorithm is easy to achieve and has wide using prospects.

Problems solved by technology

However, this work did not take into account the obvious color tone differences between different images when reconstructing real-world objects, making it difficult to effectively eliminate the seams in texture mapping results.

More importantly, the above methods only focus on the seam problem caused by the different light intensities on both sides of the boundary.

In fact, in addition to different light intensities, camera calibration errors and some other system errors will also lead to seams, which are difficult to eliminate directly with image smoothing methods
