The invention discloses a method for quickly starting a reversing image based on an Android system. According to the technical scheme, quick starting can be achieved, radar tortoise maps and touch event responses can be provided quickly after an android system is started, switching of camera data streams is not involved in the process, a client can well experience reversing images to assist reversing in the reversing process, and the safety performance is improved. By adopting the method, about 4 seconds after the system is started, a reversing image is provided, a parking application is started in about 11 seconds, the parking application is in communication connection with evs, through message interaction, the parking application starts to render a background, a radar map and other pictures, rendering is completed, and the evs transmits the background through setting an alpha map layer transparent transmission mechanism. Therefore, reversing images can be rapidly provided in about 4seconds, and functions of touch radar and the like can be provided in about 11 seconds.
本发明公开了一种基于安卓系统快速启动倒车影像的方法,既能够快速启动,又能在android系统起来后迅速提供雷达乌龟图,触摸事件响应,且过程中不涉及摄像头数据流的切换,让客户在进行倒车过程中,能够很好的体验倒车影像来辅助倒车,增加了安全性能。采用本发明方法,系统开机启动后4秒左右evs启动提供倒车影像,在11秒左右启动泊车应用,该泊车应用与evs进行通信连接,通过消息交互,泊车应用开始渲染背景以及雷达图等画面,渲染完成,evs通过设定alpha图层透传机制将背景透传出来。从而实现4秒左右快速提供倒车影像,并在11秒左右能提供触摸雷达等功能。
