LidarFrame ouster::sdk::core::frame_ops::select_by_index(const LidarFrame &frame, const std::vector<size_t> &indices, bool update_metadata = false)

Create a new LidarFrame containing only selected beam rows.

Copies header fields and selected pixel field rows into a new frame. Non-pixel fields are copied as-is.

Parameters:

  • frame[in] Source lidar frame. Must have sensor_info set.

  • indices[in] Beam row indices to select. Must be unique and within [0, frame height).

  • update_metadata[in] If true, the output frame’s sensor_info is updated to reflect the selected beams. Defaults to false.

Throws:

std::invalid_argument – If frame has no sensor_info, or indices are invalid.

Returns:

New LidarFrame with only the selected beam rows.
