Method and system for determining relationship among text segments in signboards for navigating autonomous vehicles

A text segment recognition system for determining relationship among text segments in a signboard for navigating an autonomous vehicle, the text segment recognition system comprising:

• a processor;
• and
• a memory, communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which on execution, cause the processor to:
• capture one or more images of the signboard using one or more image capturing devices associated with the autonomous vehicle;
• determine one or more text regions, forming plurality of text segments, in each of the one or more images;
• identify one or more text nodes in each of the one or more text regions;
• determine relationship among the one or more text regions by identifying relationship among each of the one or more text nodes corresponding to the one or more text regions;
• cluster each of the one or more text regions based on the relationship among each of the one or more text regions for determining the relationship among the plurality of text segments in the signboard;
• and
• provide information related to the relationship among the plurality of text segments to a navigation unit, associated with the autonomous vehicle, for facilitating navigation of the autonomous vehicle.

A non-transitory computer readable medium including instructions stored thereon that when processed by at least one processor cause a text segment recognition system, associated with an autonomous vehicle, to perform operations comprising:

• capturing one or more images of the signboard using one or more image capturing devices associated with the autonomous vehicle;
• determining one or more text regions, forming plurality of text segments, in each of the one or more images;
• identifying one or more text nodes in each of the one or more text regions;
• determining relationship among the one or more text regions by identifying relationship among each of the one or more text nodes corresponding to the one or more text regions;
• clustering each of the one or more text regions based on the relationship among each of the one or more text regions for determining the relationship among the plurality of text segments in the signboard;
• and
• providing information related to the relationship among the plurality of text segments to a navigation unit, associated with the autonomous vehicle, for facilitating navigation of the autonomous vehicle.
