Embodiment Construction

[0041] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0042] In related technologies, self-driving cars use video cameras, radar sensors, and laser range finders to understand the surrounding traffic conditions, and use high-precision maps to navigate the road ahead. Therefore, when there is no high-precision map on the driving road section, the positioning, perception and planning control of the self-driving car will be subject to many restrictions, making automatic driving impossible. However, due to geographical diversity, many places may not have corresponding high-precisio...

Abstract

The invention provides a high-precision map generation method and device and computer equipment. The method comprises the following steps: obtaining a local high-precision map and a destination in anautomatic driving automobile; judging whether the front road section has a corresponding high-precision map or not according to the destination and the local high-precision map; and if the front roadsection has no corresponding high-precision map, prompting the driver to switch to a manual driving mode, acquiring map information through a radar and a camera of the automatic driving automobile after entering the front road section, and generating a high-precision map. Therefore, the destination and the local high-precision maps of the automatic driving automobile are obtained; when it is determined that the corresponding high-precision map does not exist on the front road section, the map information is further collected to generate the high-precision map, the use area of the high-precision map is enlarged, the safety of automobile driving is improved, and therefore popularization of automatic driving automobiles is better facilitated, and the urban traffic condition is improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a method, device and computer equipment for generating high-precision maps. Background technique [0002] With the continuous development of intelligent transportation technology, intelligent vehicle technology is gradually being widely used, and autonomous driving vehicles have become a hot research topic. At present, self-driving car technology uses video cameras, radar sensors, and laser rangefinders to understand the surrounding traffic conditions, and uses high-precision maps to navigate the road ahead to achieve autonomous driving. [0003] However, due to the diversity of regions, not all roads have corresponding high-precision maps. Therefore, when there is no high-precision map on the road section where the self-driving car is driving, the positioning, perception and planning control of the self-driving car will be subject to many constraint...
