Title:
OBJECT POSITION ESTIMATION DEVICE, OBJECT POSITION ESTIMATION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/260780
Kind Code:
A1
Abstract:
The present invention robustly and with high precision estimates the respective positions of objects, even if the objects overlap in an image. An object position estimation device (1) is provided with: a feature extraction unit (10) including a first feature extraction unit (21) which generates a first feature map by subjecting a target image to a convolution computation process, and a second feature extraction unit (22) which generates a second feature map by also subjecting the first feature map to the convolution computation process; and a likelihood map estimation unit (20) including a first position likelihood estimation unit (23) which, by using the first feature map, estimates a first likelihood map indicating the probability that objects having a first size are present in each position of the target image, and a second position likelihood estimation unit (24) which, by using the second feature map, estimates a second likelihood map indicating the probability that objects having a second size, which is greater than the first size, are present in each position of the target image.
