Automatic tie point measurement in Erdas generate wrong placed tie points

[Ahmadabusaleh]

Hello All

 

I couldn’t figure out why the Erdas 2015 generates a wrong placed tie points when I use Automatic tie point generation measurement, have a look at the below example.

 

Here is the procedure of my  work:

1- I have added tie points on the images (Manually added  3 tie points on shared locations in different images).

2- then I have added the GCPs.

3- I run the Automatic tie point measurement

4- the result was for example in image 1 the point was located at a tree while its located on a house in image2 and located on a street in image 3.

 

What might be the issue here ?!
