摘要
随着街景数据的广泛应用,移动街景采集设备已经成为当前的一个热点研究领域。腾讯地图新一代车载街景采集系统针对现有设备操作繁琐、供电不稳、同步精度低等主要问题,提出系统改进方法,分别做了全景平台自动升降电动推杆实现,车载多设备电源自主设计集成,相机、激光雷达和惯导之间的精确时间同步。该文就该系统的总体设计、关键技术及工程实现等进行了详细论述。
With the wide application of street-scene data, mobile device of street-scene data acquisition has became one hot research topic. According to the main problems such as tedious operation, fluctuant power supply, and low synchronization precision of existing devices, the new generation of Tencent map vehicle street-scene acquisition system proposed a modified method. This system realizes independent stable power supply for vehicle multi-device, and implements automatic lifting of panoramic platform by electric handspike, precision time synchronization of camera, laser radar and Inertial Navigation System by velocimeter and integration navigation. This paper gives a detailed description of general design, key techniques and project realization of this acquisition system.
