The invention relates to a site-in-the-loop test system and test method oriented to the vehicle-road cooperation technology, and belongs to the technical field of vehicle-road cooperation test. The system comprises a perception fusion layer, a data transmission layer and an application layer, and point cloud data are recorded and played back to form a virtual test environment; and according to the method, the tested vehicle can interact with the virtual vehicle in the virtual test environment in the site, various extreme scenes are repeatedly drilled, so that the test method with consistency and repeatability is constructed, a convenient, efficient and low-cost test scheme is provided for the V2X to-be-tested vehicle/equipment, and the test result is closer to the performance in the real environment. 本发明涉及一种面向车路协同技术的场地在环测试系统及测试方法，属于车路协同测试技术领域，该系统包括感知融合层、数据传输层和应用层，通过录制点云数据并回放形成的虚拟测试环境，使被测车辆可在场地内与虚拟测试环境中的虚拟车辆进行互动，反复演练各种极端场景，从而构建具备一致性、可重复性的测试方法，为V2X待测车辆/设备提供方便、高效、低成本的测试方案，并使测试结果更加贴近真实环境中的表现。
