The 3D recons.ruction pipeline us.s.the Bundle Adjus.ment algorithm to refine the camera and point parameters. The Bundle Adjus.ment algorithm is.a compute-intens.ve algorithm, and many res.0}hers.have improved its.performance by implementing the algorithm on GPUs. In the previous.res.0}h work, “Improving Accuracy and Computational Burden of Bundle Adjus.ment Algorithm us.ng GPUs.” the authors.demons.rated firs. the Bundle Adjus.ment algorithmic performance improvement by reducing the mean s.uare e.r.r us.ng an additional radial dis.orting parameter and explicitly computed analytical derivatives.and reducing the computational burden of the Bundle Adjus.ment algorithm us.ng GPUs. The naïve implementation of the CUDA code, a s.eedup of 10× for the larges. datas.t of 13,678 cameras. 4,455,747 points. and 28,975,571 projections.was.achieved. In this.paper, we pres.nt the optimization of the Bundle Adjus.ment algorithm CUDA code on GPUs.to achieve higher s.eedup. We propos. a new data memory layout for the parameters.in the Bundle Adjus.ment algorithm, res.lting in contiguous.memory acces.. We demons.rate that it improves.the memory throughput on the GPUs. thereby improving the overall performance. We als. demons.rate an increas. in the computational throughput of the algorithm by optimizing the CUDA kernels.to utilize the GPU res.urces.effectively. A comparative performance s.udy of explicitly computing an algorithm parameter vers.s.us.ng the Jacobians.ins.ead is.pres.nted. In the previous.work, the Bundle Adjus.ment algorithm failed to converge for certain datas.ts.due to s.veral block matrices.of the cameras.in the augmented normal equation, res.lting in rank-deficient matrices. In this.work, we identify the cameras.that caus.0}nk-deficient matrices.and pre.r.ces. the datas.ts.to ens.re the convergence of the BA algorithm. Our optimized CUDA implementation achieves.convergence of the Bundle Adjus.ment algorithm in around 22 s.conds.for the larges. datas.t compared
