Questions about cameras in the data set #34
Description
Hello, thank you for your wonderful sharing. Recently, I extracted the original picture information from the rosbag format files of the cave data set and cemetery data set you shared before, and found that the occurrence frequency of the left and right images was unstable, resulting in a large difference in time stamps, and there was a pause in the middle, resulting in a different number of pictures from the left and right cameras. In addition, the original rosbag information had duplicate messages. For example, there are 13794 messages retrieved by rosabag info in the cave data set, but because there are actually 60 duplicate picture messages, I only 13734 pictures extracted. These problems may be the cause of frame loss and delay in the algorithm. Do you have any solutions?
