Homework 2

Camera Calibration

Due Date: 03/12

  • Download: Here it is!
  • Calculate the equivalent distance of the real world in 1 pixel of the digital camera for each Focal length & Object displacement & Object distance.
  • You may have to find the parameters (sensor width = 2x.x mm) of the digital camera you are using.
  • Please specify the parameters you are using, i.e., focal lenght, object length, etc.
  • Please tabulate your result in your report, there may be error between the true "theoretical" value and the value you measured, but don't worry.

    • Announcement

  • You may use any programming language of your choice to implement the functions, provided that you do not use any library calls except for basic image IO (e.g. OpenCV).
  • Failing to provide a report will reduce your grade by 1~2 levels.
  • Using restricted functions within your program (unless specified) will result in a failure of your work.

    • FAQ

  • Q1: 請問作業二，報告的表格中需要那些數值?
      題目有 3 種 focal length (18mm,53mm,135mm)。
      對於每個focal length，有 3 種object distance (600mm,1200mm,1800mm)。
      而對每種 object distance ，有5張影像，0mm 為基準影像，其餘 4 張(1mm,5mm,10mm,20mm) 為用來和 0mm 做比較算出 mm/pixel 。
      故報告中總共需要 3 x 3 x 4 = 36 個 FOV theoretical vs measured 的比較。
