operate() with double** as input (vector input)

[yan]

Hi,

I'm new to ceres and trying to solve a sparse problem with every sub problem defined based a subset of the variables. Code structure is as following.  sub_cam only saves the pointers to the subset variable. However, I got following messages:

'bool Nonrigid_Control_Sparse_PointToPlaneError::operator ()(const T *const *,T *) const': could not deduce template argument for 'const T *const *' from 'const double *const '  \internal\variadic_evaluate.h 176. 

Is there anyway to solve this? Thank you.

double cam[600];

vector<double*> sub_cam;

for (int j=0;j<4;j++)

{

  for (int k = 0; k < 6; k++)

  {

   sub_cam.push_back(&cam[neighbor_graph[selected_id[i]][k]]);

   }

}

   ceres::CostFunction* cost_function = Nonrigid_Control_Sparse_PointToPlaneError::Create(dst[i], src[i], dst_normal[i], neighbor_weight[selected_id[i]]);

   problem.AddResidualBlock(cost_function, NULL, sub_cam);

template <typename T>

bool operator()(T const *const * camera, T* residuals) const {

;

}

Have solved the problem by decomposing sub_cam as several continuous blocks and then pass them to the cost function as problem.AddResidualBlock(cost_function, NULL, sub_cam[0], sub_cam[1],...)
