“前程质远”2026前列腺癌质控水平高质提升项目在进博会签约无人机光流测试发现分辨率会改变模型间的差距
远处无人机在画面上只有几个像素，轮廓不清时，微小的移动仍能提供定位线索。FlyingDrones团队用物理渲染生成带逐像素位移真值和分割掩码的图像，并按画面尺寸归一化误差。在三个分辨率、999对图像上，研究者比较了16类模型。它们都胜过假设目标完全静止的基准，但在1920×1080分辨率下，不同架构之间的差距更清楚。 Laurenz Ruzicka等人的这项研究收录在11月6日更新的计算机科学预印本列表中。
团队还用21台相机拍摄的真实无人机视频复核结果。在41个模型检查点上，合成测试与真实视频评价的排名相关系数为0.63，具体名次并未完全一致。另一项实验只用800对合成图像微调，在留出的样本中，无人机区域误差最多降低37%。同一架构的不同训练版本表现也可能相差很大，比较时需同时说明所用训练数据。
