Machine vision-based display terminal operation response matching detection device

Abstract

The invention provides a machine vision-based display terminal operation response matching detection device, which is used for detecting whether the operation response of a display terminal is accurate. The device comprises a mechanism operation unit, a to-be-detected image acquisition unit, a template image pre-storing unit, an image positioning and matching unit and a display unit, wherein the mechanism operation unit is used for operating a to-be-detected device according to steps; the to-be-detected image acquisition unit is used for acquiring a to-be-detected image displayed by the display terminal through a camera; the template image pre-storing unit is used for storing a template image which correctly responds to each operation; the image positioning and matching unit is used for performing positioning and matching processing on the template image at the to-be-detected image and judging whether the current display result is correct; and the display unit is used for outlining an approximate region of the template image in a gray image of the to-be-detected image and marking an unmatched pixel point when the display terminal displays error. According to the device, the matching accuracy reaches a single pixel point level, so that the accuracy and the precision for judging the matching degree are greatly improved; and the device has higher detection speed and is suitable for intelligent detection of the conventional terminal.

Description

technical field [0001] The present invention relates to the technical field of intelligently detecting whether the operation response of a display terminal is accurate, relates to a technology for locating and matching a small image with a small angle of rotation or translation in a large image, and specifically relates to a display terminal operation response matching based on machine vision detection device. Background technique [0002] The electronics industry has developed very rapidly in recent decades, especially electronic products such as smart phones and tablet computers that can bring people comfort and convenience in life, and have become necessities of modern people's lives. In today's society, the replacement speed of such products is getting faster and faster, and people's requirements are getting higher and higher. When users use this kind of electronic products, the most intuitive experience is obtained from the display terminal, that is, the LCD screen, so...
