3D measurement and record XY-Coordinates of objects/pixels in a room

[pantharhe]

Hi everyone,

I am fairly new to PS and kindly like to ask you, if anyone might have a solution for this problem:

I have several 3-D pictures of rooms and know the lenght of one side (the x-axis of a coordinate system).

On the ground of the room are certain (approx. 100 - 200) tiny objects, from which I do have to know the exact 3-D X-Y coordinates related to the left front corner of the room (Lets say, the left front corner is point 0/0 in an X-Y coordinate system).

So far I am familiar with measuring distances in 3-D using the plane and measurment tool of the vanishing point option (which actually works great!).

But it is a hell of work (and error-prone) to measure and then to write down the exact x-y-coordinates of each single object!

Does anyone know an option to lay a 3-D (to the vanishing point adapted) coordinate system above the room and then to record the object/pixel position by simply "clicking" on them?

I would be glad about your answer and help!

Best,

Jakob

That would require a genuine photogrammetry tool.

Hey Mylenium!

Thank you, for your answer.

I found the solution:

1. Measure the side distances via PS.

2. Use and calibrate the raster of KINOVEA (a small, free but very nice program to analyze sport movements) with the length data of PS and insert (and move) the integrated coordinate system in KINOVEA.

3. Use the marker option of KINOVEA and simply click on the objects to get the right 3D-coordinates.

4. Export data to csv.

The combination of both programs works great!

Best,

Jakob
