Ich habe mit Feature-Extraktion und Epipolare Geometrie gearbeitet. Allerdings komme ich immer wieder auf die folgenden Fehler:Warnung: Konvertieren von Nicht-Fließkommadaten in einzelne
Warning: Converting non-floating point data to single. In pdist2 (line 219) In extractFeaturesU (line 93)
Die Codezeile, die eine Warnmeldung zurückkehrt ist:
[distance, position] = sort(pdist2(double(repmat(featuresA, size(xPoints, 1))), featuresB), 2, 'ascend');
Der Teil des Codes die obige Zeile enthält unten angezeigt .
%% extract features
corresponding = [];
rightBound = size(sharpImageB, 2);
xPoints = 3 : 3 : rightBound - 3;
for index = 1 : size(realWantedPoints, 2)
%extract features from wanted points

yPoints = -(liner(3) + (liner(1) * xPoints))/liner(2);

yB = corresponding(:, 2);
Was ist der Datentyp von FeaturesB? –
