Title:
MAP INFORMATION PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/170997
Kind Code:
A1
Abstract:
Provided is a map information processing device which contributes to the improvement of high-precision map verification performance by generating road information at a traffic lane level for a verification purpose by functioning as a means for extracting a road area corresponding to a road and a demarcation line corresponding to a traffic lane from an aerial image (for example, a ground photo photographed from an aircraft or a satellite), inferring the position of an object/structure (occlusion) which may cover the road, determining whether or not the demarcation line in the vicinity of the occlusion forms a continuous line by using the inferred occlusion position and demarcation line information, and next determining whether or not the traffic lane in the vicinity of the occlusion has continuity such that a misunderstanding about the continuity of the road when the presence of no occlusion is possible can be avoided to suppress the inclusion of incorrect information. This device generates traffic lane information which can be also used to generate appropriate traffic lane information for an area for which road information cannot be extracted due to an occlusion by using a satellite image/aerial photo for a map information verification purpose.
