Abstract: A map service providing method and a map service providing system based on autonomous driving simulation testing is disclosed.

Abstract: A method for processing a Measurement Data Format (“MDF”) file includes determining a file offset address of a data block of interest in the MDF file, and adding an indexing table containing a thread pointing to the file offset address to the MDF file. The method further includes sending the indexing table and data retrieved from the MDF file to a database for caching.

Abstract: The present disclosure provides a method, apparatus and computer program product for suppressing noise in 3D road surface reconstruction. The method includes: acquiring an image related to a road surface; extracting horizontal line information and ROI (region of interest) information from the image, wherein the horizontal line information comprises a horizontal line pixel value, and the ROI information is used to perform 3D road surface reconstruction for the road surface; judging whether the difference between the horizontal line pixel value and a preset horizontal line pixel value is greater than a pixel threshold; judging whether the horizontal line pixel value is greater than a compensation threshold when the difference is greater than the pixel threshold; determining a compensation value based on the difference when the horizontal line pixel value is not greater than the compensation threshold; and adjusting the ROI information based on the compensation value.
