a A scheme illustrating four camera angles (30°, 45°, 60°, and 90°). The origin for angle measurement is the center position of the stirrer. b Vial positioning detection performance (mAP) as a function of the testing view angle. c A scheme illustrating a ground-truth image involving two failure cases, one each with the lean-in and stand-on statuses. d The scenes and their corresponding detection results with DenseSSD for each tested camera angle. The failure vial cases are highlighted in yellow dotted lines for clarity. At 45° and 60°, both failure cases were correctly detected. At 30° and 90°, the vial in the lean-in status was incorrectly predicted as the success case.
