Bus detection for an autonomous vehicle

摘要

Methods and systems are provided that may allow an autonomous vehicle to discern a school bus from image data. An example method may include receiving image data indicative of a vehicles operating in an environment. The image data may depict sizes of the vehicles. The method may also include, based on relative sizes of the vehicles, determining a vehicle that is larger in size as compared the other vehicles. The method may additionally include comparing a size of the determined vehicle to a size of a school bus and based on the size of vehicle being within a threshold size of the school bus, comparing a color of the vehicle to a color of the school bus. The method may further include based on the vehicle being substantially the same color as the school bus, determining that the vehicle is representative of the school bus.

主权项

1. A method comprising:
using, by one or more processors of a computing device, image data indicative of one or more vehicles in an environment to select a vehicle from the one or more vehicles to be a candidate school bus; based on the selection of the vehicle to be the candidate school bus, the one or more processors making a comparison of one or more features of the vehicle to one or more known features of a school bus; based on the comparison, determining a confidence level representing a likelihood that the vehicle is a school bus; and based on the confidence level exceeding a predetermined threshold, the one or more processors determining that the vehicle is a school bus.
