I have a camera with a fisheye lens. I need to simulate it on blender to get the same images

camera properties: sensor size: 2/3". image resolution: 1360*1024 fisheye focal: 1.8mm H*V (FOV): 185*185 (with 2/3"). here is the link for the fisheye lens fisheyelens and the camera GC1380

My problems is how to fix the V field of view ? I have chose a fisheye equisolid and I set a focal length as 1.8 and the FOV =185 as H filed of view. But the horizontal field of view is determined by the W/H image resolution which different to 1 in the real case. Any help?

  • $\begingroup$ Which camera and what lens do you use? $\endgroup$ – p2or May 8 '15 at 8:20
  • $\begingroup$ @poor, All details are in the question (line 2). $\endgroup$ – BetterEnglish May 8 '15 at 12:29
  • $\begingroup$ Yeah, but I meant which real camera (model, manufacturer), lens (model, manufacturer)? $\endgroup$ – p2or May 9 '15 at 12:36

    $\begingroup$ I see you really want this answered, can you post some picture from the camera and some render you are getting and how they differ? This will help a little with answering (I don't have that camera). These images would be best of some grid like pattern. $\endgroup$ – Jaroslav Jerryno Novotny May 12 '15 at 19:19

Looking at the specs form the manufacturer you can see the dimensions of the sensor:

enter image description here

Using simple math you can determine the sensor's active area to be 8.78mm wide and 6.61mm tall.

Input those on the vertical and horizontal size values for the sensor and create a preset for future use.

enter image description here

Set the lens and field of view. to 1.8mm and 185 degrees.

Now set the render size on your scene to the dimensions of your camera:

  • $\begingroup$ What is the difference between your solution and my configuration. I have done the same thing! I think that it have to change the aspect ratio to get the right angle. $\endgroup$ – BetterEnglish May 18 '15 at 18:53
  • $\begingroup$ your calculation of the sensor size is not true. the size sensor is 6.6*8.8 which gives 11mm as diagonal size $\endgroup$ – BetterEnglish May 18 '15 at 19:11
  • $\begingroup$ 11mm diagonally is what sony lists as the sensor size... $\endgroup$ – cegaton May 18 '15 at 19:15
