I first met the assertion fail in the function minMaxLoc , I am sure that there is nothing wrong with my input because I imwrite and check it successfully.
code:
//minMaxLoc(discreteImg, &minDiscreteVal, &maxDiscreteVal, //minMaxLoc(Img, &minVal, &maxVal, NULL, NULL, discreteImg>0);
minDiscreteVal Img>0);
minVal = 15.5;
maxDiscreteVal maxVal = 21.5;

Then I just guess the max and min values of instead of using this function , but another assertion fail happens.
I get this project from my classmate, but it works normally in his computer with the same VS2015 and OPENCV 3.4.3
It costs me 2 days and I still can not find out why.I finally solve this because I use wrong vc lib. My vs version is 2015 but I use vc15 lib library .After changing to vc14 , it works.
