Embodiment 1

[0040] see figure 1 , Embodiment 1 of the present invention provides a method for displaying map data, including the following steps:

[0041] Step S10, according to the shape point of the lane line, in the pre-collected road environment picture set, determine the road environment picture including the lane line, wherein the lane line is made based on the laser point cloud.

[0042] In this step, the lane line is obtained by producing the lane line from the laser point cloud data collected by the laser radar (Lidar) installed on the collecting vehicle. The technical selection of the lane line manufacturing technology does not affect the implementation of the embodiments of the present invention. Therefore, the embodiments of the present invention do not impose any restrictions on the lane line manufacturing technology. The road environment picture can be obtained by shooting equipment (such as industrial camera, camera, etc.) installed on the collecting vehicle. Among them,...

Embodiment 2

[0063] see image 3 , the second embodiment of the present invention provides a display device for map data, including the following modules:

[0064] The determining module is configured to determine a road environment picture including the lane line in the pre-collected road environment picture set according to the shape point of the lane line, wherein the lane line is made based on the laser point cloud.

[0065] The first acquisition module is used for acquiring the projection matrix and attitude information of the laser that generates the laser point cloud.

[0066] The second acquisition module is configured to acquire the internal and external parameter matrix of the camera that collects the road environment picture including the lane line.

[0067] The establishment module is configured to use the projection matrix, the attitude information and the inner and outer parameter matrix to establish the transformation matrix of the laser point cloud and the pixel points in ...

Abstract

The invention discloses a lane line data display method, which comprises the steps of determining a road environment picture containing a lane line in a pre-collected road environment picture set according to a shape point of the lane line, the lane line being manufactured based on laser point cloud; obtaining a projection matrix and attitude information of laser for generating the laser point cloud; acquiring an internal and external parameter matrix of a camera for acquiring a road environment picture containing the lane line; establishing a transformation matrix of the laser point cloud and pixel points in the road environment picture by utilizing the projection matrix, the attitude information and the internal and external parameter matrixes; based on the transformation matrix, obtaining pixel points corresponding to the shape points of the lane lines in the road environment picture, and connecting and displaying the pixel points corresponding to the shape points of the lane lines in the road environment picture. According to the technical scheme, an operator can conveniently, rapidly and accurately determine the missing position of the lane line data, the lane line manufacturing accuracy is guaranteed, and meanwhile the manufacturing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of electronic maps, in particular to a method, device and electronic equipment for displaying map data. Background technique [0002] As an indispensable part of smart cities, autonomous driving technology has become a hot spot in the development of today's automobile industry, and high-precision maps are the core of autonomous driving. In the process of autonomous driving, high-precision maps can be used in scenarios such as positioning, assisting in perceiving the environment, planning routes, and driving decisions. [0003] High precision Figure 1 It generally includes lane lines on the road, roadside ancillary facilities such as guardrails, road signs, etc. Since the usage scenarios of high-precision maps are closely related to the driving safety of vehicles, the quality inspection of high-precision maps is an important part of the production process of high-precision maps. However, how to chec...
