Embodiment Construction

[0081] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0082] In the embodiment of the present invention, by collecting two-dimensional street view images, three-dimensional point clouds and inertial navigation data, the attributes of the target aerial road signs are detected from the two-dimensional street view images, and the three-dimensional point cloud and two-dimensional street view image are realized by means of inertial navigation data. The registration of the 3D point cloud after registration is used to determi...

Abstract

The embodiment of the invention provides a data processing method, a data processing device and a terminal. The data processing method comprises the following steps: collecting road data, wherein the road data comprise a two-dimensional street scene image, three-dimensional point cloud and inertial data; detecting the attributes of a target air road mark from the two-dimensional street scene image, wherein the attributes comprise positions and sizes; registering the three-dimensional point cloud and the two-dimensional street scene image in a three-dimensional space based on the inertial data; determining three-dimensional coordinates of the target air road mark by adopting the registered three-dimensional point cloud. The data processing method provided by the invention has the advantages that the air road mark can be detected from the two-dimensional street scene image, the precision of a detecting result is increased, and the practicability of data processing is increased.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to the technical field of road data processing, and in particular to a data processing method, device and terminal. Background technique [0002] In the existing fields of vehicle navigation, vehicle automatic driving, and driving safety reminders, the detection and extraction of air road signs such as signal lights and speed limit signs is an important technology. At present, the processing scheme for aerial road signs is mainly carried out manually, specifically: obtain the 3D point cloud of the road scene space, and then manually extract the aerial road signs directly from the 3D point cloud; the manual detection method is cumbersome and inefficient. Wrong, less practical. Contents of the invention [0003] Embodiments of the present invention provide a data processing method, device, and terminal, which can improve the accuracy of detection results and improve the p...
