Question

please write for me following steps in Paragraph Format in a perfect way and correct any mistakes . please .

1-we use paint program to find the image coordinates ( colum , row ) for each tie and control point for the 4 photos .

2- find the photo Coordinates ( x, y ) for each tie and control point in mm using the equation .

3- we calculate the horizontal distance AB for the control points by using equation .

4- calculate the flying hieght ( H ) for the control points using equation.

5- we use 2D similarity to design the Matrix A and Matrix B , and finding the External Orientation Parameters ( EOPs ) for the ground control points by using equations .

6- we use parallax equation for each tie point .

7- we calculate the number of the unknown parameters and was founded to be = control ( 4 x 6 ) + tie ( 10 x 3 ) = 54 unknown.

8 .we calculate the number of equations and was founded to be =88 equation .
Image 1 = 9 x 2 = 18
Image 2 = 11 x 2 = 22
Image 3 = 13 x 2 = 26
Image 4 = 11 x 2 = 22

9-number of unknown (54) x 30% = 16.2 .
And 16.2 + 54 = 70.2 < 88 , which is good .

10- we calculate ( m11, m12, m13, m21, m22, m23, m31,m32, m33 ) for each photo.

Answer 1

Answer-

Image coordinates have two values one stands for row and other for column; both the image coordinates are found with the help of paint program for each of tie and control point of photo. This process is followed for four given photos and the value of image coordinate for each photo is converted in millimeters (mm), this will help in calculating the properties like distance and height for the control points of each photo. Use of similarity matrix is done to find External orientation parameters (EOPs)and use of parallax equation is done for the tie points. By following this process the unknown parameters for control points were found to be equal to 6 x 4 = 24 and for ties found to be 10 x 3 = 30 thus total 54 unknowns were found. Number of equation for image 1, 2, 3 & 4 were found to be 9 x 2 = 18, 11x 2 = 22, 13 x 2 = 26, 11x 2 = 22 respectively , thus total 88 equation for found. A check is performed which implies that sum of number of unknown and its 30 percent must be less than the number of equations found. Thus, 30 percent of number of unknown is equal to 16.2, which in addition to 54 equals to 70.2 and that is less than number of equations which is equal to 88. Finally the values for m for different positions like m11, m12, m13, m21, m23, m31, m32, m33 for each photo can be calculated.
