Why self compiled Opencv is slower than apt-get package?

Hi community.

I have 2 opencv package: one is self-compiled opencv3.1 with cuda and the other is installed using sudo apt-get install ros-kinetic-opencv3.

When I tried the same program on different packages, it appears my self compiled package is much slower than that in ROS.

Ex> Template matching with ORB

My opencv3.1        : 150 - 200 ms per frame 
ROS opencv3.2.0-dev : 40~50ms per frame

This is tested in python, but I also find my c++ codes have a similar result.

Here shows getBuildInformation() result in each version.

What flags did you compile it with? Did you make sure to include all the optimizations your processor can use?

The answer should be found by calling

std::cout << cv::getBuildInformation();

(or the python equivalent) for both builds and compare the output.

Actually, tomasth is correct. Can you edit your question with the getBuildInformation() from both versions? There should be some obvious differences.

Also, just to check, is your processor an ARM processor? Or is it Intel or AMD?

Hi. I added my getBuildInformation result. And my machine is 64bit arm.

Two things.

I notice you have OpenCL disabled. That could do it.

Secondly, they use the NVIDIA HAL called carotene. You should see an option in the WITH section of your cmake named WITH_CAROTENE. Give that a try.
