Abstract

The invention relates to a driving assistance data acquisition method and system. The method comprises the steps: obtaining system statistical data through an ADAS system, and transmitting the systemstatistical data to a multimedia system; acquiring vehicle positioning data; packaging the system statistical data and the vehicle positioning data as acquisition decision data and sending the acquisition decision data to a cloud server; after receiving a data acquisition instruction downloaded by the cloud server, sending the data acquisition instruction to data acquisition equipment; acquiring target data based on the data acquisition frequency in response to the data acquisition instruction; and packaging the target data through the multimedia system and sending the packaged target data tothe cloud server for storage. Through crowdsourcing mode data acquisition, the hardware cost is reduced, and the problem of insufficient data coverage is solved. And the cloud adopts a decision algorithm to flexibly adjust the data acquisition frequency of each ADAS terminal so as to reduce invalid and repeated sample acquisition.

Description

technical field [0001] The invention relates to the field of driving assistance, in particular to a method and system for collecting driving assistance data. Background technique [0002] In the past decade, advanced driver assistance systems for smart cars have made remarkable achievements in improving driving safety, such as the development of forward collision warning systems and automatic emergency braking systems. In the research and development process of advanced driving assistance systems, data collection is an essential link. For Level 2 driving assistance systems, it is generally necessary to collect 300,000 to 1 million kilometers of image data, millimeter-wave radar data, etc. for the training of perception models, recognition models, and early warning models. As the driving assistance system develops to a higher level, and when the model is mainly based on deep learning data-driven models, the amount of data required for model training and optimization will inc...
