Method and apparatus for generating map

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively connected to the at least one processor;
• wherein,
• the memory comprises instructions executable by the at least one processor therein, and when the instructions are executed by the at least one processor, the at least one processor is configured to:
• obtain a street view image corresponding to a target road;
• input the street view image into a preset recognition model to obtain data of a candidate isolation belt corresponding to the street view image, the data of the candidate isolation belt comprising information of the candidate isolation belt and a probability corresponding to the information of the candidate isolation belt, wherein the isolation belt comprises physical objects existing on a road for isolation and virtual lines for isolation;
• correct the information of the candidate isolation belt based on a preset correction strategy and the probability to obtain information of a target isolation belt;
• and
• add an icon corresponding to the information of the target isolation belt on a base map comprising the target road to generate a map;
• wherein a plurality of candidate isolation belts are comprised, and the at least one processor is configured to:
• determine a confidence of information of each candidate isolation belt;
• determine whether information of a first candidate isolation belt having the confidence greater than a first preset threshold and information of a second candidate isolation belt having the confidence less than or equal to a second preset threshold are comprised, the second preset threshold being less than the first preset threshold;
• and
• in response to determining that the information of the first candidate isolation belt and the information of the second candidate isolation belt are comprised, correct a type of the second candidate isolation belt comprised in the information of the second candidate isolation belt to a type of the first candidate isolation belt comprised in the information of the first candidate isolation belt.

A non-transitory computer-readable storage medium, having a computer instruction stored thereon, wherein the computer instruction is configured to cause a computer to perform a method for generating a map, the method comprising:

• obtaining a street view image corresponding to a target road;
• inputting the street view image into a preset recognition model to obtain data of a candidate isolation belt corresponding to the street view image, the data of the candidate isolation belt comprising information of the candidate isolation belt and a probability corresponding to the information of the candidate isolation belt, wherein the isolation belt comprises physical objects existing on a road for isolation and virtual lines for isolation;
• correcting the information of the candidate isolation belt based on a preset correction strategy and the probability to obtain information of a target isolation belt;
• and
• adding an icon corresponding to the information of the target isolation belt on a base map comprising the target road to generate a map;
• wherein when a plurality of candidate isolation belts are comprised, correcting the information of the candidate isolation belt based on the preset correction strategy and the probability to obtain the information of the target isolation belt comprises:
• determining a confidence of information of each candidate isolation belt;
• determining whether information of a first candidate isolation belt having the confidence greater than a first preset threshold and information of a second candidate isolation belt having the confidence less than or equal to a second preset threshold are comprised, the second preset threshold being less than the first preset threshold;
• and
• in response to determining that the information of the first candidate isolation belt and the information of the second candidate isolation belt are comprised, correcting a type of the second candidate isolation belt comprised in the information of the second candidate isolation belt to a type of the first candidate isolation belt comprised in the information of the first candidate isolation belt.
