Question

嗨，这是模板匹配的代码。我正在做8种不同模板的匹配。现在问题是我想无限期地运行该程序。但是当我试图插入一个无限循环时，我的程序运行一次，我得到了错误：

我在打印参考和模板图像的深度，宽度，类型和高度后观察到，在'for'循环的一个完整循环之后，模板的参数被更改。我认为这是数据损坏的问题。我对这个问题感到无助。请帮我。

avenger@ubuntu:~/opencv/opencv-2.4.9/finalproject/templet_matching$ ./temp 
init done 
opengl support available 
Referece Image Mat Width:960
Referece Image Mat Hight:720
Referece Image Mat depth:0
Referece Image Mat type:16

Saved new_ref008.jpg

在for循环的第一个周期中模板一个数据

Template Matched 
Referece Template Mat Width:190
Referece  Template Mat Hight:195
Referece  Template Mat depth:0
Referece  Template Mat type:16

Template Matched 
Template Matched 
Template Matched

Template Matched 
Template Matched 
Template Matched 

Referece Image Mat Width:800
Referece Image Mat Hight:600
Referece Image Mat depth:0
Referece Image Mat type:16

for循环1个循环后的模板一个数据

Referece Template Mat Width:611
Referece  Template Mat Hight:406
Referece  Template Mat depth:5
Referece  Template Mat type:5
