求解圆心怎么输出！求大神指点！

求解红色处这两个值怎么输出：center.x ,center.y 在控制台或者加一个label输出都行 能输出就行。

写log，MessageBox ?

[wjain]

printf("[%d, %d]", center.x ,center.y);

不知道你用什么类型来保存坐标点的`~
int就是 %d
float就是 %f

[赵4老师]

重建所有

[Alexander]

话说LZ这段代码写在哪的？main？事件？

[Alexander]

center.x = cvRound((r->x + nr->x + nr->width*0.5)*scale);
center.y = cvRound((r->y + nr->y + nr->height*0.5)*scale);
printf("[%d, %d]", center.x ,center.y);
输不出东西？

[赵4老师]

在每个最后不带\n的printf后面加fflush(stdout);

printf("[%d, %d]\n", center.x ,center.y);
或者
printf("[%d, %d]", center.x ,center.y);fflush(stdout);

这个我试过 不好用，完全不输出啊亲 控制台还是只显示detection time

难道程序输出默认被重定向了?
你试试输出到文件`~

[heykaokao]

我在上面的xy下面加上PRINTF 就能输出 下面就不行。为虾米呢
