Bundle adjustment on a graph processor
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. Webthe standard BA. The graph network is built upon the factor graph used in the BP-based BA. 2.2. Learning to Simulate Complex Dynamics by Graph Networks Graph networks (GNs) [5] are a type of graph neural net-works [21]. Receiving a graph as input, a GN outputs a graph of the same shape but with different attribute values at their nodes and …
