我正在使用 cv::projectPoints 来获取 3D 点向量的对应像素。
这些点都彼此靠近。
问题是,对于某些点,我得到正确的像素坐标,但对于其他点,我得到奇怪的负值,例如 -22599 ...
cv::projectPoints 返回负值是正常的还是我的代码中的错误?
void SingleCameraTriangulator::projectPointsToImage2(const std::vector< cv::Vec3d >& pointsGroup, const double scale, std::vector< Pixel >& pixels)
{
cv::Vec3d
t2, r2;
decomposeTransformation(*g_12_, r2, t2);
cv::Mat imagePoints2;
cv::projectPoints(pointsGroup, r2, t2, *camera_matrix_, *distortion_coefficients_, imagePoints2);
for (std::size_t i = 0; i < imagePoints2.rows; i++)
{
cv::Vec2d pixel = imagePoints2.at<cv::Vec2d>(i);
Pixel p;
p.x_ = pixel[0];
p.y_ = pixel[1];
if ( (p.x_ < 0) || (p.x_ > ((1 / scale) * img_1_->cols)) || (p.y_ < 0) || (p.y_ > ((1/scale) * img_1_->rows)))
{
cv::Vec3d point = pointsGroup[i];
std::cout << point << " - " << pixel << " - " << pixel*scale << "problema" << std::endl;
}
p.i_ = getBilinearInterpPix32f(*img_2_, scale * p.x_, scale * p.y_);
pixels.push_back(p);
}
}
提前感谢您的任何建议。
