Title:
IMAGE PROCESSING DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/016994
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve highly accurate detection of obstacles even in adverse weather environments, particularly environments in which a scatter phenomenon caused by fog or the like occurs. A target signal processing unit 51 calculates a cross-correlation function between split reference light from a light source unit 201, and reflected light from a target T, said reflected light being obtained using split signal light from the light source unit 201. An estimation unit 52 estimates scattering characteristics of propagation paths of the signal light and the reflected light. A correction processing unit 53 executes, on the basis of the scattering characteristics estimated by the estimation unit 52, prescribed correction processing of the cross-correlation function calculated by the target signal processing unit 51.
