Title:
LEARNING-BASED GROUND POSITION ESTIMATION
Document Type and Number:
Japanese Patent JP2020077410
Kind Code:
A
Abstract:
To provide a ground position positioned by a start point of a trajectory of an object.SOLUTION: Operations of the present disclosure include: acquiring a plurality of images taken by a camera over time in environment; identifying a first position of an object in a target region of the environment in a first image of the plurality of images; identifying a second position of the object in a second image of the plurality of images; determining an estimated trajectory of the object on the basis of the first position of the object and the second position of the object; and on the basis of the estimated trajectory, estimating a ground position in the environment associated with a starting point of the estimated trajectory of the object. Additionally, the operations include providing the ground position associated with the starting point of the estimated trajectory of the object for display in a graphical user interface.SELECTED DRAWING: Figure 3
