Method, apparatus, device, and storage medium for image processing

A method for image processing, comprising:

• performing line feature extraction on a first image and a second image to be matched, respectively, to obtain a plurality of first line segments and a plurality of second line segments;
• determining a plurality of first intersection points corresponding to the plurality of first line segments and a plurality of second intersection points corresponding to the plurality of second line segments;
• matching the plurality of first intersection points and the plurality of second intersection points to obtain a plurality of matching point pairs, wherein each matching point pair comprises a first intersection point and a corresponding second intersection point;
• and
• determining a plurality of matched target line segments in the first image and the second image based on the plurality of matching point pairs.

An electronic device, comprising:

• a processor, and
• a memory communicatively connected to the processor;
• the memory storing computer-executable instructions;
• wherein the processor executes the computer-executable instructions stored in the memory to perfom acts comprising:
• performing line feature extraction on a first image and a second image to be matched, respectively, to obtain a plurality of first line segments and a plurality of second line segments;
• determining a plurality of first intersection points corresponding to the plurality of first line segments and a plurality of second intersection points corresponding to the plurality of second line segments;
• matching the plurality of first intersection points and the plurality of second intersection points to obtain a plurality of matching point pairs, wherein each matching point pair comprises a first intersection point and a corresponding second intersection point;
• and
• determining a plurality of matched target line segments in the first image and the second image based on the plurality of matching point pairs.

A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed by a processor, causing acts to be performed, the acts comprising:

• performing line feature extraction on a first image and a second image to be matched, respectively, to obtain a plurality of first line segments and a plurality of second line segments;
• determining a plurality of first intersection points corresponding to the plurality of first line segments and a plurality of second intersection points corresponding to the plurality of second line segments;
• matching the plurality of first intersection points and the plurality of second intersection points to obtain a plurality of matching point pairs, wherein each matching point pair comprises a first intersection point and a corresponding second intersection point;
• and
• determining a plurality of matched target line segments in the first image and the second image based on the plurality of matching point pairs.
