Problems solved by technology

[0004] In the above solution, due to differences in the clock and data collection frequency between different sensors, the time when different sensors collect data for the same scene is not synchronized, which leads to different scenes of data collected by different sensors at the same collection time. , which in turn makes it difficult to obtain synchronously collected data

Abstract

The embodiment of the invention provides a data acquisition method, a system and a device, electronic equipment and a storage medium, and relates to the technical field of computers, the method is applied to a control platform, and the method comprises the following steps: sending an exposure control signal to a camera according to a first time period to control exposure of the camera; sending a phase control signal to a laser radar according to a second time period, so that a rotary code disc of the laser radar is controlled to rotate to a preset phase angle, wherein the second time period is a common multiple of the first time period and the duration needed by the rotary code disc to rotate by one circle, the preset phase angle is a phase angle enabling the field angle of the laser radar to be aligned with the field angle of the camera, and at least the laser radar is synchronous with a clock of the control platform; and acquiring image data acquired by the camera, and acquiring point cloud data acquired by the laser radar. By applying the scheme provided by the embodiment of the invention, the synchronously collected data can be conveniently obtained.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data acquisition method, system, device, electronic equipment and storage medium. Background technique [0002] In the autonomous driving scene, it is necessary to obtain data collected by multiple sensors for the same scene, fuse the above data, and realize the environmental perception of the above scene based on the fused data. [0003] In related technologies, the above-mentioned sensors generally include a camera and a laser radar, and usually need to obtain images collected by the camera, and obtain point cloud data collected by the laser radar, and search and collect time-synchronized data from the above data as the data collected synchronously for the same scene , the above data are fused to obtain the fused data. [0004] In the above solution, due to differences in the clock and data collection frequency between different sensors, the time when different s...
