download template fingerprint to pc

[ariessetiyawan]

How to get fingerprint template so it can be used as data for fpmatch.py ​​(https://github.com/brianrho/fpmatch), can I use image_to_pc example (https://github.com/brianrho/FPM/tree/master/examples/image_to_pc)

I put the necessary dlls in the archive

Can you explain in detail how to use it?

• You should use/modify the templates example to extract all the fingerprints templates you want to search (i.e. your database), into arrays -- the template_buffer variable holds each template after readTemplate has been called, and this template is also printed in your serial monitor.

• Put all those template arrays (as a list of bytearrays perhaps) into a Python module, which will serve as your fingerprint database.

• To search for a fingerprint, you need to first capture the unknown/input fingerprint for which you're looking for a match. The enroll example shows how you can getImage() and then convert that image into a template stored in one of the sensor's buffers. You can then use some of the logic in readTemplate() to download the template from that sensor buffer into your Arduino's RAM template_buffer, just like in the templates example. Copy this "unknown template" to your Python module.

• Finally, use fpmatch.py to iterate through your database and compare each template against your "unknown template" until you get a match (or not).

I have been able to download the fingerprint template from the example you made, but I am not clear with this explanation,

but I will try to understand by trying to make the code...

To be able to take a fingerprint template, do you have to take 2 steps as in your example? Can I only enroll once?...

You can just do it once i.e. call getImage() to get an image, image2Tz() to convert the image to a template, readTemplate() to extract that template and print it to your Serial monitor. This is your "unknown/input fingerprint" i.e. userInput which is to be searched for in your database database = [correctMatch, template1, template2], to find a match.

ok, thanks for your help...my problem solved...
