Title:
METHOD AND APPARATUS FOR DETECTING GROUND ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2018/119902
Kind Code:
A1
Abstract:
A method and an apparatus for detecting ground environment, the method comprising: scanning a ground environment by using laser detection signals having different working wavelengths; receiving a reflection signal which is reflected back from the ground environment; according to the reflection signal, determining scanning point information for each scanning point of the ground environment; according to each scanning point information, determining spatial coordinate information and a laser reflection characteristic for each scanned point; dividing the ground environment into sub zones having different laser reflection characteristics; and determining the ground environment type of each sub zone. Since lasers having different working wavelengths are used to scan the ground, and ground environment type is determined according to laser reflection intensities reflected by the ground environment at different wavelengths, the sensing effect for a complex ground environment is improved and thus passable roads may be better determined.
