Abstract: Method and device for searching stripe set are disclosed herein. The method involves: receiving a raw image captured by a rolling shutter image sensor, wherein the raw image includes stripe pattern formed by flashing light source; binarizing the raw image to obtain a binary image, according to a binary threshold, wherein the binary image has two pixel values, one of the two pixel values is set as a preset first value; searching a connected domain having pixels with a first value to obtain a plurality of first connected domains, according to the pixel value in the binary image; selecting a target connected domain corresponding to the stripe pattern from the plurality of first connected domains; determining stripe set according to the target connected domain, wherein the stripe set is the set of the target connected domain corresponds to the stripe pattern.

Abstract: The present application provides a method and device for searching stripe set and a system with the same. Wherein, the method includes: a plurality of first connected domains are obtained in the binary image. A target connected domain is selected from the plurality of first connected domains. The stripe set based on the target connected domain is determined to determine a stripe pattern. A center of the stripe pattern is calculated according to the target connected domain of the stripe set. Whether the stripe set is an effective stripe set is determined based on the center of the stripe pattern. The method can eliminate the impact of incomplete stripe pattern on the image and improve the accuracy of recognition.

Abstract: A method for identifying one or more light sources may include capturing, via an imaging device, an image, the imaging device having a rolling shutter.
