Problems solved by technology

However, in addition to light fixtures, real-world scenes also contain a myriad of other objects (e.g., buildings, facilities, trees, people, lights, etc.) around the light fixture, which makes it sometimes difficult to detect light-emitting device, so that the imaging area of ​​the light-emitting device cannot be determined

Abstract

A method and system for realizing detection of a light emitting device, the light emitting device includes a controller and one or more light sources, the controller can set the light emitting mode of the light source, the method includes: using ambient light sensing The device detects the characteristics of ambient light around the light emitting device; the controller of the light emitting device sets the light emitting mode of the light source of the light emitting device according to the characteristics of the ambient light, so that the light source can exhibit different characteristics from the ambient light; The recognition device uses an image acquisition device to collect an image containing the light-emitting device, and analyzes the image to obtain the optical characteristics of the environment where the light-emitting device is located; the recognition device processes the image according to the optical characteristics of the environment and / or configuring an image capture device based on optical characteristics of the environment to recapture an image containing the light emitting device; and a recognition device analyzing the image to detect the light emitting device.

Description

technical field [0001] The present invention relates to the field of visual inspection, and in particular, to a method and system for realizing the inspection of light-emitting devices. Background technique [0002] The statements in this section are merely to provide background information related to the present invention to assist in an understanding of the present invention and this background information does not necessarily constitute prior art. [0003] With the development of science and technology, optical communication technology has been widely used. In some optical communication schemes, a light-emitting device may be used to communicate information out, and an identification device having an image capture device (eg, a camera) may be used to capture an image containing the light-emitting device to identify the information communicated out by the light-emitting device. [0004] A light-emitting device for optical communication purposes may generally include a con...
