Method for recognizing illumination state of traffic lights, electronic device, and storage medium

An electronic device comprising:

• a processor;
• and
• a storage device storing a plurality of instructions, which when executed by the processor, cause the processor to:
• acquire a first image that comprises a set of traffic lights;
• when detecting that the first image is in a backlight scene, obtain a segmentation map by dividing a first region from the first image, in which the first region is an image region of the set of traffic lights;
• extract an illumination region from the segmentation map;
• recognize a lit color of the set of traffic lights according to a position of the illumination region in the segmentation map.

A non-transitory storage medium having stored thereon at least one computer-readable instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for adjusting point cloud density, the method comprising:

• acquiring a first image that comprises a set of traffic lights;
• when detecting that the first image is in a backlight scene, obtaining a segmentation map by dividing a first region from the first image, in which the first region is an image region of the set of traffic lights;
• extracting an illumination region from the segmentation map;
• recognizing a lit color of the set of traffic lights according to a position of the illumination region in the segmentation map.
