How to create a valid template image for multi geometric patterns matching?

Go to solution

Dear All,


I'm trying to implement multiple Geometric Patterns matching. And I modified the example "Match Multiple Geometric Patterns" but keep getting error 1074395628.


What I did are:

1. Adding video flow to the example to make it match features in the video.

2. There are three preset image templates in the example, I tried to replace it with an image template created by myself but keep getting the error. I attached the image template I use.


How I created the image template:

I used several methods to create it but none of them work in the example:

1. I used the Template Editor to create a .png file;

2. I used another example called "Pattern Matching" to extract a template.



It seems that the error always appears after the "IMAQ Learn Multiple Geometric". Does anyone have some idea about what I should do? I got stuck in this for a long time. Thanks!!! I also attach the modified example below.

Hi ZY-TreeHouse,


This error sometimes comes up when an invalid template file is used. It could be either a file format issue or the image size being too large. The forum post linked below goes through a few more troubleshooting steps you can try:
