我已经为特征点的密集采样编写了 cuda 函数,但出现错误。下面给出了我的 cuda 代码。我正在使用 cuda 7.5 工具包。

{
int i = blockDim.x * blockIdx.x + threadIdx.x;
Point2f point = (*d_points)[i];
int x = cvFloor(point.x);
int y = cvFloor(point.y);
//if(x >= d_x_max || y >= d_y_max)
//continue;
x /= min_distance;
y /= min_distance;
(*d_counters)[y*width+x]++;
