Problems solved by technology

Moreover, because the sensing results are independent of each other, the overlapping areas of adjacent road-based base stations are repeatedly sensed and do not complement each other, and each independent station can only perform local tracking on targets within their respective sensing ranges.

Embodiment Construction

[0055] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0056] Such as figure 1 As shown, it is a schematic diagram of perception of the same target by two road-based base stations in the prior art. Road-based base station A and road-based base station B are adjacent sites. Both road-based base station A and road-based base station B have their own sensing ranges and their sensing ranges overlap. The target is the car, and the car enters the overlapping sensing range of road base station A and road...

Abstract

The embodiment of the present invention relates to the field of sensing technology, and discloses a multi-site subgrade network sensing method, device, terminal and system. Wherein, the method includes: constructing a global grid map of the road-based network, the global grid map is marked with the positions and sensing ranges of at least two road-based base station perception systems; receiving each of the at least two road-based base station perception systems The detection target list transmitted by the road-based base station perception system, the detection target list is a set of preset detection targets; according to the position of each road-based base station perception system, the detection target transmitted by each road-based base station perception system The list is indexed into the global grid map to generate a global tracking list; and the preset detection target in the detection target list transmitted by the ground base station sensing system is tracked according to the global tracking list. The embodiment of the present invention can realize the global tracking of the target.

Description

technical field [0001] Embodiments of the present invention relate to the field of sensing technology, and in particular to a multi-site subgrade network sensing method, device, terminal and system. Background technique [0002] In the field of vehicle-road collaboration, a comprehensive perception of the road traffic network can be achieved by building a road-based network. However, in the traditional road-based network, each road-based base station perceives independently. In this case, each road-based base station needs to be equipped with a complete set of sensing solutions. Moreover, because the sensing results are independent of each other, the overlapping areas of adjacent road-based base stations are repeatedly sensed and do not complement each other, and each independent station can only perform local tracking on the target within its own sensing range. Contents of the invention [0003] An object of the embodiments of the present invention is to provide a multi-...
