Embodiment Construction
[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0063] The types and distribution of panel lights on different devices to be tested may be different. For the convenience of discussion, the device to be tested is taken as a network device, such as a switch, as an example, which may include multiple light-emitting diode (Light-Emitting Diode, LED) type panels. Lights, these panel lights can be concentrated in a certain area of the switch panel, and can also be distributed in various areas of the switch panel...

The embodiment of the invention provides a detection method and device for a panel lamp. The method comprises the following steps that: obtaining a plurality of detection images of a panel lamp to bedetected, wherein each detection image is obtained in a way that the panel lamp to be detected is shot in a detection stage; carrying out image processing on the plurality of detection images, and determining an area where the panel lamp to be detected is positioned; according to the plurality of parts of detection images including the area where the panel lamp to be detected is positioned, obtaining the current working state, which appears in each piece of parts of detection image, of the panel lamp to be detected; independently comparing each current working state of the panel lamp to be detected with a working state stipulated in a corresponding detection state; and when each current working state is consistent with the working state stipulated in each corresponding detection state, determining that the panel lamp to be detected is normal. By use of the method, the labor cost of panel lamp detection can be lowered.
Description
technical field [0001] The invention relates to the technical field of machine vision, in particular to a detection method and device for a panel light. Background technique [0002] In order to facilitate the user to know the current working status of the device in time, the aforementioned purpose can be achieved by setting the panel light of the device itself. For example, when the device is in different working states, the control panel lights display different colors and brightnesses to show the user the current working state of the device. [0003] At present, some network devices (such as switches) can be provided with port indicator lights and function indicator lights (such as system lights, power lights, mode button lights, management network port lights, etc.) on the panels. The port indicator light can be on when the corresponding port is connected normally, and can be off when the corresponding port is abnormally connected (or not connected). In some applicatio...
