IMAGE PROCESSING METHOD AND IMAGE PROCESSING DEVICE

Title:

IMAGE PROCESSING METHOD AND IMAGE PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/075510

Kind Code:

A1

Abstract:

This image processing method is for detecting a position of a detection target from a captured image acquired periodically, wherein the following steps are repeated multiple times: a) a step (S103) for analyzing a region to be analyzed in the captured image, and deriving a detection error and the position of the detection target; and b) steps (S104 to S107) for changing the region to be analyzed on the basis of the magnitude of the detection error. Due to this configuration, the region to be analyzed can be shrunk while keeping the detection error within a prescribed range. Consequently, it is possible to reduce the amount of computation without increasing the detection error in image processing for detecting a specific object from time-series image data.
