运行要4s。。哪里不对呢 #75
Comments
是windows吧,O2优化有打开吗? |
对的,是windows。3个优化都打开了,没有打开之前需要30+s |
可能是opencv没用release模式编译? |
MSVC里面没有-O3选项,改成/O2再试试吧 |
release模式和Debug模式差异很大,创建模板,Debug模式要11s,release模式只要0.4s;匹配测试,debug模式要1s多,release模式0.55s; |
这个问题有解决吗 我也遇到相同情况 |
大神,请问下当点数为2~3千个的时候,进行匹配的时候耗时会不会很长,这种问题能够怎样解决啊,谢谢! |
不会,windows上其实也挺快的,可以参考这个issue。一般200个点够了,2000多的话,估计100万像素在200ms吧 |
QT6.2 debug版本匹配12秒,release版本0.3秒,差异确实大,找到这个issue才发现问题,还以为代码改动导致的。 |
大大你好,运行速度上好像有点问题
