matlab - How do I estimate the radial distortion parameters for a given image? -


i have found camera matrix image using dlt :

p =    3.8618e-03   7.1665e-04   1.9713e-03  -9.1510e-01   3.1222e-05   4.4639e-03  -7.6783e-04  -4.0317e-01  -5.9516e-07   1.1950e-06   1.7221e-06  -1.0115e-03

how proceed find radial distortion parameters.

tools: opencv/octave

the best thing calibrate camera. need take multiple images of planar calibration pattern, e. g. checkerboard.

if have computer vision system toolbox matlab, can use camera calibrator app.

authentication - Mongodb revoke acccess to connect test database -

i have ec2 instance mongodb 3.2.0 installed. have user admin access. can connect user , perform operation remotely. 1 can connect database test remote if knows ip mongo 11.11.11.11. although not able make operations, want restrict access user credentials can connect server. first need create users , grant roles users, example: use admin db.createuser( { user: "myuseradmin", pwd: "abc123", roles: [ { role: "useradminanydatabase", db: "admin" } ] } ) then need start server --auth parameter mongod --auth more information here

c - getting error: cannot take the address of an rvalue of type 'int' -

i tryed compile old code new compiler , got next error: error: cannot take address of rvalue of type 'int' here example 2 lines - 1 compiles , other gives error struct mstct { int myfield; int myfield2[5]; int myfield3[5]; }; typedef struct mstct db_data_px; int foo(int a, int b, int c){ //the next code compiles successfully. unsigned val1 = ((18 == c) ? ((unsigned) & (((db_data_px *) 0)->myfield)) : ((unsigned) & (((db_data_px *) 0)->myfield3[b]))); //successes //the next code failing unsigned val2 = (unsigned) & ((18 == c) ? (((db_data_px *) 0)->myfield) : (((db_data_px *) 0)->myfield3[b])); return 0; // failing } why first line compiles , second failing ? why need cast (unsigned) & in both of select expression , not enough cast after select expression valued ? in code ((18 == c) ? (((db_data_px *) 0)->myfield) : (((db_data_px *) 0)->myfield3[b])) is conditional expression not produce lva...
