Description

一种对象轨迹跟踪展示方法以及系统 技术领域
[0001] 本申请涉及计算机云计算技术领域, 特别是涉及一种对象轨迹跟踪展示方法以 及系统。
背景技术
[0002] 随着人工智能、 计算机软硬件技术的发展, 基于图像处理的安全布防系统以直 观、 方便、 内容广泛获得了快速发展并在多个公共安全领域被广泛应用。 随着 视频监控系统推广, 可有效提高案件侦破率以及提高公众安全感指数。
[0003] 为了满足公共安全监控, 需要查询监控对象或者布防对象的活动轨迹。
[0004] 对于潜在的布防对象, 因未持有追踪装置, 因此现有技术中一般采用布防对象 的图像特征来进行轨迹追踪, 在可以采集到对象的图像特征的情况下, 可根据 图像采集装置的位置信息实现实时将行人的当前位置信息展示到请求终端的地 图上。
发明概述
技术问题
[0005] 但是, 如果只是依靠采集布防对象的图像特征以及图像采集设备位置来追踪的 话, 则在公共区域会存在很大的盲区, 在该盲区中, 图像采集设备无法获取对 象的图像特征数据, 不能获取监控对象或者布防对象的位置信息, 因此无法在 请求终端上实时更新监控对象或者布防对象的轨迹, 不能将监控对象或者布防 对象的轨迹实时展示到请求终端的地图上。 因此, 5见有的安全布防系统对监控 对象或者布防对象的轨迹追踪误差很大。
[0006] 案例: 如安全布防系统展示巡逻民警的巡逻轨迹, 在请求终端的界面上需要实 时的展示巡逻民警的当前位置, 在现有安全布防系统中由于仅通过单一的对象 的图像特征采集设备作为位置信息采样点, 在巡逻民警的图像特征采集设备的 采集盲区, 无法采集巡逻民警的图像特征数据, 无法获取巡逻民警的位置数据 , 故不能准确的展示巡逻民警的实时轨迹。 [0007] 因此, 5见有的对象轨迹跟踪技术还有待于改进和发展。
