The invention relates to a driving assistance data acquisition method and system. The method comprises the steps: obtaining system statistical data through an ADAS system, and transmitting the systemstatistical data to a multimedia system; acquiring vehicle positioning data; packaging the system statistical data and the vehicle positioning data as acquisition decision data and sending the acquisition decision data to a cloud server; after receiving a data acquisition instruction downloaded by the cloud server, sending the data acquisition instruction to data acquisition equipment; acquiring target data based on the data acquisition frequency in response to the data acquisition instruction; and packaging the target data through the multimedia system and sending the packaged target data tothe cloud server for storage. Through crowdsourcing mode data acquisition, the hardware cost is reduced, and the problem of insufficient data coverage is solved. And the cloud adopts a decision algorithm to flexibly adjust the data acquisition frequency of each ADAS terminal so as to reduce invalid and repeated sample acquisition.
本发明涉及一种驾驶辅助数据采集方法及系统,方法包括:通过ADAS系统获取系统统计数据,并发送至多媒体系统;获取车辆定位数据;将系统统计数据和车辆定位数据打包作为采集决策数据发送至云端服务器;在接收到云端服务器下传的数据采集指令后,将其发送至数据采集设备;响应于数据采集指令,基于数据采集频率采集目标数据;将目标数据经由多媒体系统打包发送至云端服务器进行存储。本发明通过众包模式数据采集,降低硬件成本也解决了数据覆盖不足的问题。云端采用决策算法,灵活调整每个ADAS终端的数据采集频率,减少无效重复的样本采集。
