Problems solved by technology
[0006] However, according to the method of generating the current high-definition map, it is not easy to know where the above-mentioned change occurs in the area represented by the high-definition map, and even if the location where the change occurs is found, MMS vehicles equipped with high-definition sensors Also had to drive around the location to do the job of generating a high-res map around the location again
This update method has the problem of being inefficient in terms of time and effort

A method for updating a high-definition map according to an embodiment of the present invention may include the following steps: acquiring a two-dimensional image by photographing a target area corresponding to at least a part of the actual area represented by the three-dimensional high-definition map the image obtained; generate a three-dimensional local landmark map of the target area from the position of the landmarks within the two-dimensional image based on the position and orientation of the camera used to capture the two-dimensional image; and by considering the target area corresponding to the high-definition map Local landmark maps to update high-definition maps.
Description
technical field [0001] The present invention relates to a device and method for more efficiently updating a three-dimensional high-definition map for autonomous driving. For reference, this application claims priority based on Korean Patent Application (Application No. 10-2018-0097468) filed on August 21, 2018. The entire content of the application upon which this priority is based is incorporated herein by reference. Background technique [0002] In recent years, autonomous driving technology has received attention as the latest automotive technology. Autonomous driving means that a vehicle recognizes road conditions by itself and drives automatically without a driver's control of brakes, steering wheel, accelerator pedal, and the like. This autonomous driving technology can be said to be the key technology for realizing smart cars. [0003] For autonomous driving, three-dimensional digital maps called high-definition maps (abbreviated HD maps) need to be available. The...
