AI Technical Summary

Technical Problem

Current 3D maps lack accurate building and road textures, leading to discrepancies between digital twin maps and the real world, and high computational loads due to large texture models, resulting in delays in providing high-quality mixed reality-based route guidance.

Method used

A 3D map view generation device that pre-loads map data and models virtual objects corresponding to buildings and roads, applying normal maps with 3D vector values to generate high-quality textures in real time, adjusting object widths based on road attributes and materials, and rendering only visible areas to reduce computational load.

Benefits of technology

Provides a more realistic mixed reality-based route guidance service with high-quality textures similar to real-world buildings and roads in real time, reducing computational load and cost.

Abstract

The present invention relates to a device for generating a 3D map view, the device comprising: an interface unit for receiving sensing information from at least a sensor provided in a vehicle; a memory for storing map data; and a processor. The processor: controls the interface unit to receive traveling information of the vehicle; determines a map area from the map data on the basis of the traveling information, detects a road shape, and models a virtual road object corresponding to the detected road shape; determines a visible area from the map area on the basis of the traveling information when there is a user's request, and renders at least a portion of the modeled virtual road object included in the visible area together with at least one virtual building object included in the visible area; and generates a map view image including an image of the rendered virtual road object.
