I've followed that Instruction. I have no Lidar Lite RangeFinder, but LZ-EZ4 buid-in with px-flow. It is said the build-in LZ-EZ4 sonar data is not used.
1. Is the separate rangefinder a must for optical flow to work. If so, can I force the built-in LZ-EZ4 sonar to be the separate RangeFinder ?
2. I did calibration like the instruction above. Here is the dataLog.
It seems really BAD, flowX/Y not follow bodyX/Y at all. ( my FLOW_ORIENT_YAW seems not correct ).
Is it caused by "No RangeFinder" ? or something else ? My ground may be not well textured, like this.
Anyone can help, many thanks.
