The invention relates to a camera sharing method for an unmanned vehicle (an automatic driving vehicle or an unmanned vehicle), belongs to the technical field of images, and adopts the technical scheme that two applications can turn on the same camera at the same time, one camera is connected to a main controller through two paths of hardware replication, and the other camera is connected to the main controller through two paths of hardware replication. And then two application layer calling interfaces are realized through two independent drivers of the software driving layer, and two different applications respectively open different driving interfaces to obtain image and video data, so that the number of cameras can be reduced to a great extent, and the problem of time sequence does notneed to be considered when data of a certain camera needs to be called.
本申请涉及一种无人车(自动驾驶车辆或无人驾驶车辆)的摄像头共用方法,属于图像技术领域,本申请的技术方案中,两个应用能在同一时间打开同一摄像头,一摄像头通过硬件复制两路连接到主控制器,然后经过软件驱动层的两个独立驱动实现两个应用层调用接口,不同的两个应用各自打开不同的驱动接口获取图像视频数据,这能够很大程度上节省摄像头数量,且需要调用某个摄像头数据时,不用考虑时间先后问题。
