Classification: CPC G | IPC G

Claim 6:
7. A perception data detection device, comprising:
at least one processor; and
a memory communicatively connected with the at least one processor; wherein,
the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to cause the at least one processor to:
acquire labeled data and perception data, wherein the labeled data comprises a labeled position and a labeled type of at least one first obstacle, and the perception data comprises a perception position and a perception type of at least one second obstacle;
perform, according to a negative sample in the labeled data, rough filtering on the second obstacle in the perception data to obtain a third obstacle remaining after the rough filtering, wherein the negative sample is a non-physical obstacle;
determine a matching relationship between the third obstacle and the negative sample, and determine the negative sample having the matching relationship with the third obstacle as a target obstacle; and
determine, according to a number of the target obstacle and a number of the first obstacle, a detection result of the perception data;
wherein the instructions are executed by the at least one processor to cause the at least one processor to:
calculate, according to the labeled position of each negative sample and the perception position of each second obstacle, a distance between each negative sample and each second obstacle; and
retain the second obstacle whose distance from the negative sample is less than or equal to a preset distance to obtain the third obstacle remaining after the rough filtering.
