I can currently export camera tracking information from my own program (outside of Blender).

I would like to import this information into Blender. How do I do this? I can export the tracking co-ordinates in ASCII format as text. Is there any plugin to import them even with changing to a different format (.fbx etc.,)

Any pointers to help me get going?


How about the following function? You would just need to get your ascii data to match the XYZ/RXRYRZ.

import bpy 
import bpy.types
import time
from mathutils import *

# positions and rotates an object (globally) and create a keyframe
# at the given frame#
# Change the rotation mode to your liking.
def animate_object( obj, x, y, z, rx, ry, rz, frame_number ):
    obj.location = Vector((x,y,z))
    obj.rotation_mode = 'XYZ'
    obj.rotation_euler = Euler((rx,ry,rz))
    obj.keyframe_insert(data_path="location", frame=frame_number)
    obj.keyframe_insert(data_path="rotation_euler", frame=frame_number)


cam_positions = (
    ( 1.56,3.13,-1.83, -4.20,-2.58,-3.48 ),
    ( 1.74,3.19,-1.63, -4.40,-1.95,-3.67 ),
    ( 2.01,3.03,-1.57, -4.32,-1.61,-3.64 )

cam = bpy.data.objects["Camera"]

frame_number = 1
for frame_number, cp in enumerate(cam_positions):
    animate_object(cam, *cp, frame_number + 1)
