Today, I would like to share with you how to use python to read picture attribute information about the relevant knowledge points, detailed content, clear logic, I believe that most people still know too much about this knowledge, so share this article for your reference, I hope you can learn something after reading this article, let's take a look at it.

Get GPS information from the photo. Interchangeable image file is often referred to as EXIF (Exchangeable image file format), which is specially set for digital camera photos. It can record the attribute information and shooting data of digital photos. EXIF information does not support png,webp and other picture formats.

Use the ExifRead package in Python to read the attribute information of the image. The installation method is as follows:

Pip install exifread

Use exifread.process_file to get information about the image:

Img_path = r "bei_012744.jpg" f = open (img_path, 'rb') contents = exifread.process_file (f) f.close ()

For single-step debugging, the contents content is as follows:

GPS coordinate conversion:

The longitude and latitude information obtained through exifread is usually in the following format: latitude [28,56,109097amp 5000] longitude [112,38,436353max 10000], the conversion formula is as follows:

Degrees = degrees + minutes / 60 + seconds / 3600

[28,56,109097ax 5000] = 28 + 56 / 60 + 109097tick 5000 / 3600 = 28.939427777778

So the coordinate conversion code is as follows:

Def convert_gps (coord_arr): arr = str (coord_arr). Replace ('[,'). Replace (']','). Split (' ') d = float (arr [0]) m = float (arr [1]) s = float (arr [2] .split (' /') [0]) / float (arr [2] .split ('/') [1]) return float (d) + (float (m) / 60) + (float (s) / 3600)

Complete code:

Import exifread img_path = r "bei_012744.jpg" f = open (img_path 'rb') contents = exifread.process_file (f) f.close () lon = contents [' GPS GPSLongitude']. Printable # longitude lon = convert_gps (lon) lat = contents ['GPS GPSLatitude']. Printable # latitude lat = convert_gps (lat) altitude = contents [' GPS GPSAltitude']. Printable # relative height altitude = float (altitude.split ('/') [0]) / float (altitude.split ('/') [1]) print ("GPSLongitude:", lon "\ nGPSLatitude:", lat, "\ naltitude:", altitude)

Results:

GPSLongitude: 112.64545425

GPSLatitude: 28.93939427777778

Altitude: 58.009
