Problems solved by technology

This solution is still directly extracting road traffic markings from the 3D point cloud, which may also affect the detection results due to the sparseness, occlusion, and lack of point clouds faced by the 3D point cloud, and the manual detection method is too inefficient and error-prone , less practical

Embodiment Construction

[0059] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0060] In the embodiment of the present invention, by collecting the two-dimensional street view image, three-dimensional point cloud and inertial navigation data, the two-dimensional street view image is segmented and the ground area image is extracted by means of the three-dimensional point cloud and inertial navigation data. At least one target road traffic marking is detected in the regional image, and the three-dimensional coordinate...

Abstract

The invention provides a data processing method, a device and a terminal. The method comprises steps of acquiring road data which comprises a two-dimensional streetscape image, three-dimensional point cloud and inertial navigation data; carrying out region segmentation on the two-dimensional streetscape image based on space position relations among the two-dimensional streetscape image, the three-dimensional point cloud and the inertial navigation data, and extracting a ground region image; detecting at least one target road traffic marking in the ground region image, wherein the road traffic marking includes lane line and / or road identifications; and based on the space position relations among the two-dimensional streetscape image, the three-dimensional point cloud and the inertial navigation data, calculating a three-dimensional coordinate of the at least one target road traffic marking. In this way, the road traffic marking is detected from the two-dimensional streetscape image, so accuracy of detection results is improved and practicability of data processing is improved.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to the technical field of road data processing, in particular to a data processing method, device and terminal. Background technique [0002] In the existing in-vehicle navigation, vehicle automatic driving, driving safety prompts and other fields, the most basic and important technology is the detection technology of road traffic markings such as lane lines and road signs. At present, the mainstream technical solutions mainly include the following two. One solution is a detection method that relies on changes in ground reflectivity: the reflectivity of road traffic markings is often higher than the reflectivity of other parts of the road surface, so the road can be obtained first The three-dimensional point cloud in the scene space, and then rely on this feature to extract road traffic markings from the three-dimensional point cloud; this scheme directly detects and extracts f...
