Embodiment 1

[0025] This embodiment provides a specific process of a multi-type real-time data interpolation display method. The multi-type real-time data is time-series data, including at least one of the following types of data: V2X information, OBU vehicle trajectory, RSU original point cloud data , RSU identification result data. Usually, the frame rate of these data is relatively low, for example, the frame rate of V2X information data is usually within 10 frames per second. Obviously, this frame rate cannot meet the demand when performing the twin display of vehicle-road collaboration.

[0026] The specific process of this method is as follows figure 1 shown, including the following steps:

[0027] (1) Obtain the latest two frames of data from the real-time data. Based on this, interpolation is performed between the two adjacent frames, thereby increasing the data frame rate.

Abstract

The invention discloses a multi-type real-time data interpolation display method. The method comprises the following steps: acquiring two latest frames of data from real-time data; according to the standard frame rate, calculating the number of times needing interpolation; generating time value information of each interpolation data frame according to the standard delay; generating an interpolation data frame according to the interpolation times; according to the time value information of each interpolation data frame, generating a data frame number of the interpolation; and integrating the interpolation data frame and the real-time data frame and then storing. Aiming at the problem that the frame rates of multiple types of real-time data are inconsistent, a data frame interpolation method is adopted, so that the data frame rate is improved, and the fluency of data playback and the fusion performance among multiple types of data are ensured; the standard time delay of the data frames is uniformly set, so that playback display abnormity caused by inconsistent time when data in different formats arrive at the system is avoided; and the data frame rate after interpolation is consistent with playback display, and the problem of data accumulation caused by asynchronization of the data frame rate and the rendering frame rate is solved.

Description

technical field [0001] The invention belongs to the technical field of information processing, and relates to a multi-type real-time data interpolation display method and device. Background technique [0002] Vehicle to everything (V2X) is an important part of the construction of new information infrastructure, and the management platform is an indispensable part. The 3D information management platform based on digital twins is used to display the roadside perception results and vehicle road information such as on-board OBU. Data has become an important means of data display. The digital twin display has the characteristics of real, intuitive, and exquisite. The real-time display process uses the last data of the sending end as a display. [0003] However, during the vehicle-road collaborative twin display process, various types of real-time data have inconsistent frame rates, and some data have a frame rate that is too low (for example, the frame rate of V2X vehicle positio...
