The invention provides a holographic sensing system based on an image-level laser radar. The system comprises road information acquisition equipment, a road test terminal system and a traffic control center, road information acquisition is electrically connected to the road test terminal system and the traffic control center respectively, and the road test terminal system comprises a camera and the image-level laser radar. Long-distance and high-precision detection of a single laser radar is realized, so that the installation cost per kilometer is reduced. And meanwhile, the problem of low resolution in the current road holographic sensing system is solved, and the system is matched with a camera for use, so that high-resolution and low-cost emergency early warning is realized at the urban intersection. 本发明提出一种基于图像级激光雷达全息感知系统，其包含：道路信息采集设备、路测终端系统、交通管控中心，道路信息采集分别电性连接至路测终端系统及交通管控中心，路测终端系统包括相机、图像级激光雷达。实现单个激光雷达的长距离和高精度探测，从而降低每公里安装成本。同时解决了当前道路全息感知系统中分辨率低的问题，该系统配合照相机使用，使得在城镇交汇路口实现高分辨率，低成本的应急预警。
