Method and apparatus for generating road map, electronic device, and computer storage medium

An apparatus for generating a road map, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• input a remote sensing image into a first neural network to extract first road feature information of multiple channels via the first neural network;
• input the first road feature information of multiple channels into a third neural network to extract third road feature information of multiple channels via the third neural network, wherein the third neural network is a neural network trained by using road direction information as supervision information;
• fuse the first road feature information and the third road feature information;
• and
• generate a road map according to a fusion result.

A non-transitory computer storage medium, having stored thereon computer-readable instructions that, when being executed by a processor, cause the processor to execute the following:

• inputting a remote sensing image into a first neural network to extract first road feature information of multiple channels via the first neural network;
• inputting the first road feature information of multiple channels into a third neural network to extract third road feature information of multiple channels via the third neural network, wherein the third neural network is a neural network trained by using road direction information as supervision information;
• fusing the first road feature information and the third road feature information;
• and
• generating a road map according to a fusion result.
