摘要:

汽车摄像头,特别是全景摄像头,往往会被泥、水、雪等弄脏。对于更高级别的自动驾驶,有必要拥有一个会触发自动清洁系统的弄脏检测算法。图像中污染的局部检测对于控制清洁系统是必要的。还需要在未污染区域中启用部分功能,同时降低污染区域中的置信度。虽然这可以解决使用语义分割任务,我们探索一个更有效的解决方案,针对部署在低功耗嵌入式系统。我们提出了一种新的方法来回归的面积内的每一种污垢类型的瓷砖直接。我们称之为覆盖。所提出的方法比学习瓷砖中的主导类更好,因为瓷砖内通常会出现多种污垢类型。它还具有处理粗糙多边形标注的优点,这将导致分割任务。建议的污染覆盖解码器是一个数量级的速度比一个等效的分割解码器。我们还集成到一个目标检测和语义分割多任务模型,使用异步反向传播算法。所使用的部分数据集将作为我们WoodScape数据集的一部分公开发布,以鼓励进一步的研究。

英文摘要:

Automotive cameras, particularly surround-view cameras, tend to get soiled by mud, water, snow, etc. For higher levels of autonomous driving, it is necessary to have a soiling detection algorithm which will trigger an automatic cleaning system. Localized detection of soiling in an image is necessary to control the cleaning system. It is also necessary to enable partial functionality in unsoiled areas while reducing confidence in soiled areas. Although this can be solved using a semantic segmentation task, we explore a more efficient solution targeting deployment in low power embedded system. We propose a novel method to regress the area of each soiling type within a tile directly. We refer to this as coverage. The proposed approach is better than learning the dominant class in a tile as multiple soiling types occur within a tile commonly. It also has the advantage of dealing with coarse polygon annotation, which will cause the segmentation task. The proposed soiling coverage decoder is an order of magnitude faster than an equivalent segmentation decoder. We also integrated it into an object detection and semantic segmentation multi-task model using an asynchronous back-propagation algorithm. A portion of the dataset used will be released publicly as part of our WoodScape dataset to encourage further research.
