Problems solved by technology
[0003] In related technologies, after the data is collected, data analysis and charting are generally performed on the collected data. If there is a problem with the data during the data analysis and charting process, it is necessary to go to the site to collect it again, and the collection efficiency is too low.

The invention provides a method, device and unit for collecting map data and a storage medium. The method comprises the following steps of: detecting the signal intensity of a current position when the current position is subjected to data acquisition; if the signal intensity of the current position does not meet a signal intensity preset condition, pushing a first prompt message, wherein the first prompt message is used for indicating a driver to drive a vehicle to go to a target position and then return to the current position again, and carrying out data acquisition on the current positionagain, wherein the signal intensity of the target position meets the signal intensity preset condition; further, before the data acquisition is carried out, judging whether current parameters of various sensors of the vehicle meet the parameter preset condition or not; if so, carrying out data acquisition; further, checking the integrity and quality of acquired data when the data acquisition is carried out, and prompting to carry out data acquisition again if the requirements are not met. According to the embodiment of the invention, the collection efficiency is higher.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method, device, equipment and storage medium for collecting map data. Background technique [0002] With the advancement of science and technology, especially the development of automobile manufacturing and information technology, autonomous driving technology has become a research hotspot in recent years. Autonomous driving maps are an indispensable and important supporting technology for autonomous driving, and data collection by multi-sensor integrated mobile collection vehicles is the core channel for autonomous driving map data acquisition and one of the important links in its map production. With the rapid development of autonomous driving technology, high-precision maps are required to mature quickly to provide more accurate and vivid map data. [0003] In related technologies, after the data is collected, data analysis and charting are generally perf...
