[question]how to get the xpos and ypos on the input image？ #134

Closed KelvinQQ closed 2 years ago

KelvinQQ commented 3 years ago

according to get features from job， the xpos and ypos are not on the input image, then xpos and ypos divided by pow(2, config.getUpscaleFactor()), but the xpos and ypos are still not correct on the input image. Beacause matching two images and getting good points and findHomography and warpPerspective don't get the correct transform matrix and image

image before transform ↓ 待变换的图

transform image according to popsift ↓ 变换后的图

transform image according to opencv↓ opencv变换后的图
