WebWe show for the first time that the classical computer vision problem of bundle adjustment (BA) can be solved extremely fast on a graph processor using Gaussian Be-lief Propagation. Our simple but fully parallel implemen-tation uses the 1216 cores on a single IPU chip to, for in-stance, solve a real BA problem with 125 keyframes and Webformance computing toolbox towards speeding up bundle adjustment is the paper on multicore bundle adjustment by Wu et. al. [27]. We believe there is more work to be done to more easily expose the necessary functionality in a bundle adjustment solver without burying the user with unnecessary abstractions or hardware-speci c implementation details.
