From b62bd48b0086ef00cf293522b75a33cd532af001 Mon Sep 17 00:00:00 2001 From: Yuzviak Date: Sat, 18 Apr 2026 16:20:58 +0300 Subject: [PATCH] test(e2e): add EuRoC Mono-Depth ATE regression guard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Documents baseline for CuVSLAMMonoDepthVisualOdometry on EuRoC MH_01. ATE 0.2046m matches ORB baseline (dev/CI uses scaled ORB fallback). Ceiling 0.5m — same as ORB. EuRoC indoor != production outdoor nadir.
