WebYou'd like to match each point from db1 with a point from db2 such that the "error" of the matching, e.g. sum of distances, will be minimized. A simple greedy approach for solving this might be to generate an m x n matrix with the distances between each pair of coordinates, and sequentially select the closest match for each point. Webadditional point features on the object. In CenterPoint, 3D object tracking simpliﬁes to greedy closest-point matching. The resulting detection and tracking algorithm is simple, efﬁcient, and effective. CenterPoint achieved state-of-the-art performance on the nuScenes benchmark for both 3D detection and tracking, with 65.5 NDS and 63.8 AMOTA

"WebWe show that, for an even number n of vertices whose distances satisfy the triangle inequality, the ratio of the cost of the matching produced by this greedy heuristic to the cost of the minimal matching is at most ${}_3^4 n^{\lg _2^3 } - 1$, $\lg _2^3 \approx 0.58496$, and there are examples that achieve this bound. We conclude that this ... " - Greedy closest-point matching
