Abstract

The embodiment of the invention discloses a perceptual information fusion processing method and device, an apparatus and a storage medium. The method comprises: a set of perceptual information in a target area is received, wherein the set of perceptual information includes perceptual sub-information transmitted by different roadside apparatuses and the perceptual sub-information has a same timestamp based on time calibration among the different roadside apparatuses; and the set of perceptual information is subjected to fusion processing by using a fusion algorithm. The embodiment of the invention solves the problems that vehicle-mounted sensing devices have a small sensing range during a driving process and the cost is high for deploying more sensing devices on a vehicle, expands the sensing detection range in the driving process, reduces the deployment cost of sensing devices in a single vehicle, ensures the accuracy of fusion processing results and helps to promote the popularizationof the intelligent transportation technology.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to a method, device, device and storage medium for fusion processing of perception information. Background technique [0002] As a product of the era of "smart manufacturing" and "Internet +", intelligent driving has caused a comprehensive upgrade and reshaping of the auto industry's ecology and business models, and has played an important role in promoting national technological progress, economic development and social harmony, and enhancing comprehensive national strength. great significance. [0003] Environmental perception is the basis of intelligent driving technology. By installing sensing devices on the vehicle to perceive the surrounding environment, intelligent assisted driving can be realized. However, due to factors such as fixed positions or limited viewing angles of vehicle sensing devices, the sensing range is limite...
