Minimum OpenCV version #1

Closed robinloujun closed 5 years ago

Hi there,

thanks a lot for the nice work.

I think there should be a minimum vision (3.4.2, seeing this question) set for OpenCV, otherwise it meets error like

estimator_node.cc:(.text+0x9a1): undefined reference to `cv::Mat::updateContinuityFlag()'

Hi @robinloujun, thanks for your report. I think this might be related to some specific versions of OpenCV, like 3.3.1. In my PC or docker, it works with version 3.2.0.

You are right, the default opencv version of ros-kinetic is 3.3.1
