The invention is suitable for the technical field of data processing, and provides a data synchronization method and device, terminal equipment and a computer readable storage medium, the data synchronization method and device are applied to a detection system, the detection system comprises a camera and a radar, and the method comprises the steps that a first mapping point corresponding to a first pixel point in a first image shot by the camera is acquired, the mapping points represent three-dimensional geographic coordinates in an off-line point cloud map, and an area covered by the off-line point cloud map comprises a shooting area of the camera and a detection area of the radar; a first target point corresponding to the first mapping point is acquired, the first target point is a three-dimensional coordinate point in a first point cloud image detected by the radar, and the detection moment of the first point cloud image corresponds to the shooting moment of the first image; and synchronizing the first pixel point and the first target point. Through the method, the success rate of data synchronization of various sensors can be effectively improved.

    本申请适用于数据处理技术领域,提供了一种数据同步方法、装置、终端设备及计算机可读存储介质,应用于检测系统,所述检测系统包括相机和雷达,所述方法包括:获取与所述相机拍摄的第一图像中的第一像素点相对应的第一映射点,其中,映射点表示将离线点云地图中的三维地理坐标,所述离线点云地图覆盖的区域包括所述相机的拍摄区域和所述雷达的探测区域;获取与所述第一映射点相对应的第一目标点,所述第一目标点为所述雷达探测的第一点云图像中的三维坐标点,所述第一点云图像的探测时刻与所述第一图像的拍摄时刻相对应;同步所述第一像素点与所述第一目标点。通过上述方法,可以有效提高多种传感器数据同步的成功率。
