PCD files that I merged could not import. #1834

Open YoshikiKccs opened 3 years ago

YoshikiKccs commented 3 years ago

I want to use point cloud map I measured by using LiDAR in simulator. This point cloud's data format is PCD file. I think PCD files can be imported in svl simulator. But my point cloud file's data format could not match to PCD file format that can be handled by svl simulator. Therefore, I converted PCD file to Las file format by using Cloud Compare, which is a free software to handle point cloud data. Las files I converted could be imported in svl simulator. Next, I want to use merged point cloud map in simulator because my PCD data is small for using a map. I merged PCD files by using Point cloud library method and then I get a merged map. After that, I converted it to las file format and then put it in svl simulator. It could not, however, be imported in svl simulator and KeyNotFoundException appeared. Please teach me what is wrong and what I have to do next. スクリーンショット 2021-10-26 091332

From others using 2021.1 we have found point cloud tools sometimes have empty data that we didn't have checks for. Please try to use release 2021.3. We may have already solved this issue in this release and then we will know. Also, you are also using Ubuntu 16 which is very old. You may have problems running simulator so be aware for future releases.

@EricBoiseLGSVL Thank you for teaching me again! I got it and I will do that by using new version.
