This research introduces an advanced projection-based 3D light field reconstruction algorithm, specifically engineered to tackle the limitations of the conventional SPOC algorithm-namely its dependency on a symmetric (circular) framework and dense array image acquisition. The algorithm's core innovation resides in the utilization of disparity images captured by parallel cameras: by selecting the two cameras with positions closest to the ideal configuration, it identifies pixels most similar to the object point through their captured imagery, thereby assigning pixel values to the projected image array. Furthermore, by integrating ray tracing principles, the algorithm enables sampling with a sparse camera array, facilitating high-fidelity 3D reconstruction. Experimental results, which compare computational efficiency and display performance against the SPOC algorithm, corroborate the efficacy and advantages of this approach.
本研究介绍了一种先进的基于投影的三维光场重建算法,该算法经过专门设计,旨在解决传统SPOC算法的局限性,即其对对称(圆形)框架和密集阵列图像采集的依赖。该算法的核心创新在于利用并行相机捕获的视差图像:通过选择位置最接近理想配置的两台相机,它通过捕获的图像识别与物点最相似的像素,从而为投影图像阵列分配像素值。此外,通过整合光线追踪原理,该算法能够使用稀疏相机阵列进行采样,有助于实现高保真三维重建。将计算效率和显示性能与SPOC算法进行比较的实验结果证实了该方法的有效性和优势。
