Memory performance

[dawnos]

Hi guys!
I've been using libviso2 for a while. Recently I found that the ROS wrapper is memory consuming. The memory increased continuously when I ran viso2_ros. But to my knowledge, visual odometer should not behave like this. Is it storing something else? Do any body meet this problem?

Problem solved. Do not use opencv3.

Hi Dawnos,

I'm having exactly same problem. Now I'm using ZED camera to feed video to viso2 and when I run libviso2, my memory keep increasing. I did find that my viso2 was using Opencv3 before and I switched it back to opencv2. however the problem is still there.

Have you recompiled viso2? Which version of opencv2 do you use(by apt-get or compile by yourself)?
As I know, zed SDK requires opencv3. Have you uninstall opencv3 totally?

Thanks for reply. Yes I did some changes in my CMakelist in viso2 and recompiled it using catkin. I check in the build directory that it is linked to opencv2.4.8. Do I really need to uninstall opencv3? I have virtual environment for opencv3 and local version of opencv is 2.4.8. They are mutually independent. 2017-04-13 19:26 GMT-07:00 dawnos <[email protected]>:

You can use ldd executable to see which version of opencv does your viso2 link to actually. If it uses opencv2, it may be some problem else.
