摘要翻译：
在自动驾驶的背景下，在计算机发出接管请求的情况下，人类可能需要接管，实现驾驶安全的关键一步是监控手，以确保司机为这种请求做好准备。这项工作，侧重于这一过程的第一步，即定位手。这样的系统必须在各种恶劣的光照条件下实时工作。本文在原有的OpenPose工作的基础上，提出了一种快速的ConvNet方法，用于全身关节的估计。该网络以较少的参数进行修改，并使用我们自己的日间自然主义自动驾驶数据集进行重新训练，以估计驾驶员和乘客手腕和肘部的关节和亲和力热图，总共8个关节类别和每个腕肘对之间的部分亲和力场。该方法在多名司机和乘客身上以40 fps的速度实时运行真实世界的数据。该系统在定性和定量方面都得到了广泛的评价，在关节定位和臂角估计方面显示了至少95%的检测性能。

英文摘要：
In the context of autonomous driving, where humans may need to take over in the event where the computer may issue a takeover request, a key step towards driving safety is the monitoring of the hands to ensure the driver is ready for such a request. This work, focuses on the first step of this process, which is to locate the hands. Such a system must work in real-time and under varying harsh lighting conditions. This paper introduces a fast ConvNet approach, based on the work of original work of OpenPose for full body joint estimation. The network is modified with fewer parameters and retrained using our own day-time naturalistic autonomous driving dataset to estimate joint and affinity heatmaps for driver & passenger's wrist and elbows, for a total of 8 joint classes and part affinity fields between each wrist-elbow pair. The approach runs real-time on real-world data at 40 fps on multiple drivers and passengers. The system is extensively evaluated both quantitatively and qualitatively, showing at least 95% detection performance on joint localization and arm-angle estimation.
