Failed on Ouster LiDAR OS1-64 Gen 1

[samsdolphin]

Hi, I'm testing on the Newer College Dataset with the Ouster OS1-64 Gen 1 LiDAR. I have modified the parameters such as LidarModel, topic_lidar and topic_imu, etc. in the file simu.yaml. However, the program failed with the following error:

Load dataset from /media/sam/T7/OldCollege/long_experiment/out.bag

May I know how to fix it? Thank you!

Hi, did you solve the problem?

嗨，我正在使用Oster OS1-64 Gen 1 LiDAR在较新的大学数据集上进行测试。我已经修改了文件中的参数，如 和 等。但是，程序失败，并出现以下错误：LidarModel``topic_lidar``topic_imu``simu.yaml

我可以知道如何解决它吗？谢谢！

你解决这个问题了吗

你解决这个问题了吗

不好意思，我没解决，跑这个数据集我直接用了固定的外参。

Hi, I countered the same issue. I think this may be due to they fixed the num_firing_ to 2048, but the ouster rosbag was recorded in 1024x20 mode.

OA-LICalib/include/sensor_data/lidar_ouster.h

Line 49 in 50af680

: ouster_ring_No_(ring_no), num_firing_(2048) {}

With the bag recorded in 2048x10 mode, this error was resolved.
