Abstract

A learning method for selecting specific information, to be used for updating an HD Map is provided. And the method includes steps of: (a) a learning device instructing a coordinate neural network togenerate a local feature map and a global feature vector by applying a coordinate neural network operation to a coordinate matrix; (b) the learning device instructing a determination neural network togenerate a first estimated suitability score to an N-th estimated suitability score by applying a determination neural network operation to the integrated feature map; (c) the learning device instructing a loss layer to generate a loss by referring to (i) the first estimated suitability score to the N-th estimated suitability score and (ii) a first Ground Truth(GT) suitability score to an N-th GTsuitability score, and perform backpropagation by using the loss, to thereby learn parameters of the determination neural network and the coordinate neural network.

Description

[0001] priority claim [0002] This application claims priority over U.S. Provisional Application No. 62 / 798,656, filed January 30, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a learning method and a learning device for an automatic driving vehicle, in particular to reconstructing a three-dimensional space, updating a HD map (high definition map, High Definition Map), the learning method and the learning device, and using the learning method and learning Device test method and test device. Background technique [0004] Recently, the autonomous driving technology of vehicles has attracted much attention. The so-called autonomous driving technology refers to the technology that uses modules that can obtain external information from sensors, cameras, etc. mounted on the vehicle to collect external information and use it to drive the vehicle safely. [0005] High-definition maps are indispe...
