I found getPerspectiveTransform counld get results from release and debug mode are different, The following is my data:

dst: [0, 0] [101, 0] [101, 60] [0, 60]

release mode result: [0.8554490168548095, 1.595945597898663e-016, -296.8123008430522; -2.775557561562891e-017, 0.8602150537634458, -322.5376449092761; 8.239936510889834e-018, 5.204170427930421e-018, 1]
