卡罗影像APP是上海卡罗网络科技有限公司为道路管理、道路养护、路政、工程建设、设计院和相关施工企业量身定制的智能影像识别和展示平台。 本APP可提供基于电子地图的影像中心服务,在线查看道路、桥梁、设施及施工现场的视频,及时获取非法闯入、安全隐患等影像报警信息。通过道路巡查车智能识别发现路面病害、隐患等,形成道路巡查报告和资产盘点报告,为后续的养护分析决策提供可视化、可量化依据。 利用手机和拍照和定位功能,实现养护人员的实时轨迹记录和病害定点上报,并根据养护流程对发现病害、处置意见、养护处理、结果考核行程闭环。 【温馨提示】 轨迹巡查功能会持续使用GPS定位服务,切换至后台状态时,仍会保持GPS连接,相比其他操作会消耗更多电量。
