Collecting device for road landscape information and locating information

Abstract

The invention discloses a pick device of road landscape information and positioning information including positioning information acquisition unit used for collecting positioning information of road; road landscape information acquisition unit used to collect road landscape information; control unit was used to monitor the said positioning information acquisition unit and road landscape information acquisition unit and match the locator data with road landscape data; storage unit, used for the storage of the locator data and road landscape data matched by control unit. With the technical program by the invention can improve acquisition accuracy.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a collection device for road landscape information and positioning information used for making electronic maps. Background technique [0002] In the field of electronic map production, a total station is generally used, combined with a Global Positioning System (Global Position System, referred to as GPS) measurement or triangulation method to collect road and point of interest (Point of Interest, referred to as POI) positioning information, on this basis through The road landscape information is collected by taking pictures with cameras or marking and recording on the map, and the time and latitude and longitude coordinate information of the road landscape information are determined by manual recording and numbering. [0003] Since the above technology does not solve the synchronous collection of location information and attribute information of roads and POIs, the human fac...

AI Technical Summary

Problems solved by technology

[0003] Since the above technology does not solve the synchronous collection of location information and attribute information of roads and POIs, the human factors in the collection process are large and the accuracy is low. If the collection personnel omit information points, they need to add information collection elements or correct the collection data after the collection operation is completed. For inspection and verification, the actual road conditions cannot be completely and comprehensively reproduced indoors only by going to the collection site again to carry out operations

[0004] The data format of Chinese patent application number CN98125290.7 is BMP (Bitmap, bitmap) format, which is static data. This patent only uses the video camera as a digital camera for continuous use, and does not use the characteristics of continuous shooting of the video camera to perform video stream and audio stream. data collection

This method is suitable for the small number of static BMP photos, and the matching accuracy is sufficient to meet the matching requirements. For video and audio data streams, the accuracy to the minute cannot meet the matching requirements.

And the patent application is only for audio capture

[0005] Chinese Patent Application No. CN200410023622.2 mainly considers the combination of audio data and positioning data for supplementary data collection, but does not provide other information such as road landscape video

The disadvantage is that there is only audio and no video data

And the patent application only collects static images in JPG format

CN98125290.7 only carried out audio collection, and neither involved video or audio data joint collection

[0006] In addition, only GPS positioning is used in the prior art. If the GPS antenna is blocked, accurate positioning information cannot be obtained, resulting in low acquisition accuracy.
