find where an image is taken

how it works

this is a toy project, which uses resnet (mostly) to compare your input image with selected range of street view images, effectively get a possible address of the input image.


  • input image looks like ./query/query-class/query.jpg
  • street views downloaded from -q query_string -r region is put under database/search
  • check the log file for details


  • Q: why do you need to "query" for street views from baidu map? A: yeah it doesnt make sense, if you already knew what to query, why bother using this tool?. well first, i dont have a beast-like machine for resnet computing, if i downloaded thousands of images and comparing them with my input, im afraid its not possible. second, if there are some store fronts in your picture, you can use them to narrow down query range, which in turn reduces the time cost. anyways, consider this a demo

  • Q: baidu map doesnt have much resources to locate my pic A: Google's place photos api might be a good choice too

how to make it more useful

yeah it can be pretty useful, for private detectives, or cops, or, stalkers

if you want better performance, consider the following:

  • a huge street view resource, better without downloading, my toy has taken care of image caching, in case you dont know
  • a GPU server maybe
  • distributed searching is also worth a shot
