摘要:

各种深度估计模型现在广泛用于许多移动和IoT设备上,用于图像分割、散景效果渲染、对象跟踪和许多其他移动任务。因此,具有可以在低功率移动芯片组上快速运行的高效且准确的深度估计模型是非常关键的。在这项移动人工智能挑战赛中,目标是开发基于深度学习的单图像深度估计解决方案,该解决方案可以在物联网平台和智能手机上显示实时性能。为此,参与者使用了一个大规模的RGB到深度数据集,该数据集是由ZED立体相机收集的,能够为位于50米以内的物体生成深度图。所有模型的运行时都在Raspberry Pi 4平台上进行了评估,其中开发的解决方案能够以高达27 FPS的速度生成VGA分辨率的深度图,同时实现高保真度的结果。在挑战中开发的所有模型也与任何基于Android或Linux的移动设备兼容,本文提供了它们的详细描述。

英文摘要:

Various depth estimation models are now widely used on many mobile and IoT devices for image segmentation, bokeh effect rendering, object tracking and many other mobile tasks. Thus, it is very crucial to have efficient and accurate depth estimation models that can run fast on low-power mobile chipsets. In this Mobile AI challenge, the target was to develop deep learning-based single image depth estimation solutions that can show a real-time performance on IoT platforms and smartphones. For this, the participants used a large-scale RGB-to-depth dataset that was collected with the ZED stereo camera capable to generated depth maps for objects located at up to 50 meters. The runtime of all models was evaluated on the Raspberry Pi 4 platform, where the developed solutions were able to generate VGA resolution depth maps at up to 27 FPS while achieving high fidelity results. All models developed in the challenge are also compatible with any Android or Linux-based mobile devices, their detailed description is provided in this paper.
