在使用添加残差块时,我是 Ceres Solver 的新学习者
problem.AddResidualBlock( new ceres::AutoDiffCostFunction<Opt, 1, 6> (new Opt(Pts[i][j].x, Pts[i][j].y, Pts[i][j].z, Ns[i].at<double>(0, 0), Ns[i].at<double>(1, 0), Ns[i].at<double>(2, 0), Ds[i], weights[i]) ),
NULL,
param );
其中参数是双[6];
struct Opt
{
const double ptX, ptY, ptZ, nsX, nsY, nsZ, ds, w;
Opt( double ptx, double pty, double ptz, double nsx, double nsy, double nsz, double ds1, double w1):
ptX(ptx), ptY(pty), ptZ(ptz), nsX(nsx), nsY(nsy), nsZ(nsz), ds(ds1), w(w1) {}
template<typename T>
bool operator()(const T* const x, T* residual) const
{
Mat R(3, 3, CV_64F), r(1, 3, CV_64F);
Mat inverse(3,3, CV_64F);
T newP[3];
T xyz[3];
for (int i = 0; i < 3; i++){
r.at<T>(i) = T(x[i]);
cout<<x[i]<<endl;
}
Rodrigues(r, R);
inverse = R.inv();
newP[0]=T(ptX)-x[3];
newP[1]=T(ptY)-x[4];
newP[2]=T(ptZ)-x[5];
xyz[0]= inverse.at<T>(0, 0)*newP[0] + inverse.at<T>(0, 1)*newP[1] + inverse.at<T>(0, 2)*newP[2];
xyz[1] = inverse.at<T>(1, 0)*newP[0] + inverse.at<T>(1, 1)*newP[1] + inverse.at<T>(1, 2)*newP[2];
xyz[2] = inverse.at<T>(2, 0)*newP[0] + inverse.at<T>(2, 1)*newP[1] + inverse.at<T>(2, 2)*newP[2];
T ds1 = T(nsX) * xyz[0] + T(nsY) * xyz[1] + T(nsZ) * xyz[2];
residual[0] = (ds1 - T(ds)) * T(w);
}
};
但是当我输出 x[0] 时,我得到了这个:
[-1.40926 ; 1, 0, 0, 0, 0, 0]
在我将 x 的类型更改为 double 之后
我收到了这个错误:
note: no known conversion for argument 1 from ‘const ceres::Jet<double, 6>* const’ to ‘const double*’
在
bool operator()(const double* const x, double* residual) const
我的代码有什么问题?非常感谢!
