NAOMI MEASUREMENTS

Getting measurements from the real thing is advisable if you need the accuracy, and it is definitely not as simple as just putting a protractor on the screen, you need to take into account of the perspective of the photo.

I had a spare couple of minutes and played around with Sketchup which has a photo matching tool, built a very generic model of the cab and measured off the angles.

The angle in purple is 69.1 degrees, and the angle in blue is 24.6 degrees from the vertical (however this measurement was harder to estimate as the white frame in the picture blends with the background, making it harder to draw in 3D.

 

great work but does this conspond to real world?

 

Accuracy tends to drop off the further away the detail in the image is from where the camera is. However I'm pretty confident with the measurements I checked because the angles you wanted are fairly simple to estimate.

It's as close as I can manage as I don't have it physically available to measure. I have done the modelling process on massive commercial buildings and it does give a reasonable degree of accuracy.

 

thank you.

ill go with it.
