Abstract
A method includes obtaining a roadside sensing result that indicates a first group of location points that are of a traffic participant sensed by a first roadside device in a preset time period, and a multi-source fusion sensing result that indicates a second group of location points obtained by fusing a plurality of groups of location points that are of the traffic participant and that are obtained by a plurality of sensing devices in the preset time period; matching the roadside sensing result with the multi-source fusion sensing result; and generating first sensing capability information of the first roadside device based on the matching result.
Claims20
A first roadside device comprising:
- a memory configured to store programming instructions;
- and
- at least one processor coupled to the memory and configured to execute the programming instructions to cause the apparatus to:
- obtain a roadside sensing result indicating a first group of location points of a traffic participant in a preset time period;
- obtain a multi-source fusion sensing result indicating a second group of location points that is a fusion of third groups of location points that are of the traffic participant and that are from sensing devices in the preset time period;
- match the roadside sensing result with the multi-source fusion sensing result to obtain matching results of target location points, wherein the matching results comprise a true positive (TP) indicator, a false negative (FN) indicator, or a false positive (FP) indicator for the target location points, wherein the TP indicator indicates a target location point of the target location points is in the second group with a first matching location point in the first group, wherein the FN indicator indicates the target location point is in the second group without a second matching location point in the first group, and wherein the FP indicator indicates the target location point is in the first group without a third matching location point in the second group;
- and
- generate first sensing capability information of the first roadside device based on the matching results, wherein the first sensing capability information indicates a first region and a first sensing capability of the first roadside device in the first region.

- and
- based on the sensing capability information:
- generate warning prompt information;
- adjust a confidence of information that is about the region and that is from the roadside device;
- or
- plan a driving route bypassing the region.
