Title:
画像特徴点の動き情報の決定方法、タスク実行方法およびデバイス
Document Type and Number:
Japanese Patent JP7305249
Kind Code:
B2
Abstract:
A method for determining motion information of an image feature point, comprising: determining a first image and a second image, the first image and the second image comprising the same object; determining, on the basis of a target feature point on the object in the first image, a first pixel area including the target feature point in the first image; determining, according to a pixel difference between a plurality of first pixel points in the first pixel area and the target feature point, a second pixel area including the target feature point in the first image, the pixel difference between a plurality of second pixel points in the second pixel area being greater than the pixel difference between the plurality of first pixel points, the number of the plurality of second pixel points being the same as that of the plurality of first pixel points, and the pixel difference being used to indicate the degree of variation of pixel values of a plurality of pixel points; and acquiring, according to the plurality of second pixel points and the second image, motion information of the target feature point, the motion information being used to indicate a change in the position of the target feature point in the first image and the second image.
