It does not make any sense to me, consider re-wording the post.

Do you want number rocognition from image file?

I 'm sorry. My english is really bad. and thank you for trying to help me.

I use Opencv Template matching. Now I can get the position (x,y) of each template (example 1, 3, 2, 4, 6, 5, 7, 8)
i want method coding to check sequence of position in template.
From picture the result that I want is 1 2 3 4 5 6 7 8. how do i check?

Thank you.

I still don't understand your problem.

You have images, and you can match them, and have their positions (x,y). Then what is stopping you in just rearranging the X, Y is the matched images?

I think he's trying to form a sensible string (when reading from left to right, top to bottom) from a set of detected characters.

You can use scan line algorithm to track lines along the image and fuzzily decide what symbol goes to what line. I am afraid there is no exact algorithm.
Consider the following case:

It can be 12345 and 13425.
