Abstract

The invention discloses a high-precision map making method based on depth learning, which relates to the technical field of high-precision map making. The high-precision map making method comprises the following steps: using a vision system and a positioning system to collect image information and position information; classifying and labeling the high-precision map elements and scenes in the image information; adopting the depth learning algorithm to train the image recognition model according to the image annotation results; according to the training results of the image recognition model and the collected position information, performing the precise measurement of the elements of the high-precision map; Checking manually the errors in the training results of the image recognition model,and optimizing and the image model iteratively, which indicates the precision and automaticity of the high precision map measurement; and automatically synthesizing the high-precision maps based on the optimized image recognition model. The method can solve the problems that the original information collection of the existing high-precision map is difficult, the manufacturing process is complex,the automation degree is low, and the manual input cost is large.

Description

technical field [0001] The invention relates to the technical field of high-precision map production, in particular to a high-precision map production method based on deep learning. Background technique [0002] High-precision maps are one of the core technologies in the field of autonomous driving technology. The development of high-precision maps directly affects the safety and accuracy of autonomous driving, and is a key technical node for the implementation of autonomous driving. The core characteristics of high-precision maps are the accuracy of centimeter-level elements and the richness of elements. In order to accurately ensure the safety of autonomous driving, high-precision maps express all elements of roads and their ancillary facilities with centimeter-level precision, becoming an automatic The "eyes" of the driving car. It is precisely such high-precision and high-richness requirements that make the production process of high-precision maps a major technical pr...
