GRASS SURROGATE

摘要

Surrogates for roadside objects can be used for vehicle testing. A grass surrogate can be configured to exhibit substantially the same characteristics as natural grass when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle systems (e.g., a road departure mitigation system). The grass surrogate can help a vehicle to identify road boundaries, particularly in portions of a road that do not include lane markings. The grass surrogate can be configured to withstand being driven over by a test vehicle without being damaged and/or without damaging the test vehicle. In some arrangements, the grass surrogate can include artificial grass that is coated with a mixture of high gloss acrylic paint and high reflectance pigments.
