Embodiment Construction

[0038] 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 making creative efforts belong to the protection scope of the present invention.

[0039] figure 1 For the flow chart of the measurement method of the target provided by the embodiment of the present invention, refer to figure 1 , the method can include:

[0040] Step S100, acquiring multiple continuous single-frame point clouds.

[0041] In this embodiment, the point cloud is the vehicle-mounted laser point cloud, which is a collection of surface points along the road and the buildings on both sides thereof scanned by the laser scanner in...

Abstract

The invention discloses a target object measuring method and a high-precision map generating method and device.The target object measuring method comprises the steps that a plurality of continuous single-frame point clouds are obtained; a target single-frame point cloud is determined from the multiple continuous single-frame point clouds, and the target single-frame point cloud has a seed point of a target object; a point cloud set of the target object is determined from the multiple continuous target single-frame point clouds; coordinates of the target object are determined on the basis of the point cloud set of the target object.It is clear that the target object measuring method solves the problem that the manual workload is large due to manual measurement in the prior art.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, relates to a method for measuring an object, a method for generating a high-precision map, and a related device. Background technique [0002] With the development of the automobile industry, automobile intelligent technology (such as automatic driving technology) has received high attention. Taking autopilot technology as an example, in order to realize self-driving cars, high-precision maps need to be assisted to transmit the road condition information in front of the car to the car, so as to determine the best driving path for the car. [0003] The current high-precision map standards are: the coordinates of road ancillary facilities (such as road markings, traffic signs and traffic signs, etc.) and road crossings (such as viaducts, overpasses, etc.) The coordinates of tunnels and height limit poles, etc.), and have dynamic traffic information. Among th...
