Initializes maps for cv.remap for wide-angle

[map1, map2] = cv.initWideAngleProjMap(cameraMatrix, distCoeffs, imageSize, destImageWidth)
[map1, map2, scale] = cv.initWideAngleProjMap(cameraMatrix, distCoeffs, imageSize, destImageWidth)
[...] = cv.initWideAngleProjMap(..., 'OptionName',optionValue, ...)

Input

• cameraMatrix Input camera matrix A = [f_x 0 c_x; 0 f_y c_y; 0 0 1]
• distCoeffs Input vector of distortion coefficients [k1,k2,p1,p2,k3,k4,k5,k6,s1,s2,s3,s4,taux,tauy] of 4, 5, 8, 12 or 14 elements. If the vector is empty, the zero distortion coefficients are assumed.
• imageSize image size [w,h].
• destImageWidth

Output

• map1 The first output map. See M1Type.
• map2 The second output map. See M1Type.
• scale

Options

• M1Type Type of the first output map, default single2. See cv.convertMaps. Accepted types are:
  • int16 first output map is a MxNx2 int16 array, second output map is MxNx1 uint16 (fixed-point representation).
  • single1 first output map is a MxNx1 single matrix, second output map is MxNx1 single (separate floating-point representation).
  • single2 first output map is a MxNx2 single matrix, second output map is empty (combined floating-point representation).
• ProjType projection type, default 'EqRect'. One of:
  • Ortho
  • EqRect
• Alpha default 0
