[英]Incompatible types in DELPHI and Opencv
I am trying to find contour into a picture. 我试图在图片中找到轮廓。 I implement as follows but i get
我实现如下,但我得到
Incompatible types: 'ocv.core.types_c.pCvMemStorage' and 'UWaterShedSegment.pCvMemStorage' error.
不兼容的类型:“ ocv.core.types_c.pCvMemStorage”和“ UWaterShedSegment.pCvMemStorage”错误。
type
pCvMemStorage = ^TCvMemStorage;
pCvSeq = ^TCvSeq;
.
.
.
var
contours : pCvMemStorage;
first_contour : pCvSeq;
.
.
.
cvFindContours(DistImgEq, contours, first_contour, SizeOf(TCvContour) ,CV_RETR_LIST, CV_CHAIN_APPROX_SIMPLE,cvPoint(0,0));
You've redeclared the type pCvMemStorage
in your own unit and this is hiding the declared type in the ocv.core.types_c
unit that is required by the method signature of cvFindContours
. 你已经重新声明的类型
pCvMemStorage
在自己的单位,这是隐藏在声明的类型ocv.core.types_c
由方法签名所需的单位cvFindContours
。
Remove the type declaration from your unit and, if it is not already there, add the ocv.core.types_c
unit to your uses
clause. 从机上取下类型声明,如果它已不存在,则添加
ocv.core.types_c
单元您uses
的条款。
