Embodiment Construction

[0054] In the prior art, during the geofence drawing process, GNSS (Global Navigation Satellite System, Global Navigation Satellite System) is used as the core location reference for data collection, processing and fence judgment. Defining the extent of the geofence also cannot be applied to the optimization of fusion perception results.

[0055] Therefore, the embodiments of this specification provide a method and device for generating a hierarchical geofence. In the process of generating a geofence, a visual map is used to generate a first-level geofence, and by projecting the first-level geofence on a roadside sensor image, Match the actual geographic location, so that the location of the first-level geofence data points can be modified in real time, and the second-level geofence is generated based on the fusion result of the map data. As a reference for the reliability of the fusion result, it can effectively improve the generation efficiency of the geofence , and geofenci...

Abstract

The embodiment of the invention discloses a hierarchical geo-fence generation method and device. The method comprises the following steps: generating a first-level geo-fence by using a visual map; projecting the first-level geo-fence to a roadside sensor image, and carrying out map data fusion; starting a real-time fusion video, and judging whether the first-level geo-fence is matched with the actual geographic position on the roadside sensor image or not; if not, modifying the position of a data point in the first-level geo-fence based on the roadside sensor image; and generating a secondary geofence based on a map data fusion result. According to the hierarchical geo-fence generation method and device provided by the embodiment of the invention, the generation efficiency of the geo-fence can be effectively improved, and the geo-fence can be adjusted in real time and customized for the service scene function.

Description

technical field [0001] The embodiments of the present specification relate to the technical field of automatic driving, and in particular, to a method and apparatus for generating a hierarchical geofence. Background technique [0002] Geo-fencing (Geo-fencing) is an application of LBS (Location Based Service), which encloses a virtual geographic boundary through a virtual fence, and the mobile terminal enters or leaves the virtual geographic boundary, or Receive social services such as automatic notifications or warnings when you are active within the boundaries. [0003] The current geofence generation methods mainly include methods based on the positioning data of autonomous driving vehicles, and methods based on target recognition training based on road conditions images. The main difference between the two is the different data sources. Among them, the method for drawing a geofence based on the positioning data of the autonomous driving vehicle is to receive the positio...
