Door and window opening prompting method and system after vehicle collision
The invention discloses a door and window opening prompting method and system after vehicle collision. The method comprises the following steps: firstly, extracting a plurality of driving monitoring key frames from a driving monitoring video, respectively passing the driving monitoring key frames through a vehicle target detection network to obtain a plurality of vehicle target regions of interest, then respectively passing the plurality of vehicle target regions of interest through a ViT model to obtain a plurality of vehicle target interested semantic feature vectors, and finally obtaining a plurality of vehicle target interested semantic feature vectors; enabling the plurality of vehicle target interested semantic feature vectors to pass through a context encoder to obtain classification feature vectors, and finally enabling the classification feature vectors to pass through a classifier to obtain a classification result used for representing whether doors and windows can be opened or not. In this way, whether the risk of secondary collision occurs during door and window opening or not can be accurately judged.
公开了一种车辆碰撞后的门窗开启提示方法及系统。其首先将从行驶监控视频提取多个行驶监控关键帧分别通过车辆目标检测网络以得到多个车辆目标感兴趣区域，接着，将所述多个车辆目标感兴趣区域分别通过ViT模型以得到多个车辆目标感兴趣语义特征向量，然后，将所述多个车辆目标感兴趣语义特征向量通过上下文编码器以得到分类特征向量，最后，将所述分类特征向量通过分类器以得到用于表示门窗是否可以开启的分类结果。这样，可以对打开门窗是否会发生二次碰撞的风险进行精准判断。
