Function ouster::sdk::core::frame_ops::filter_uv

Function Documentation

void ouster::sdk::core::frame_ops::filter_uv(LidarFrame &frame, const std::string &coord_2d, size_t lower, size_t upper, double invalid = 0, const std::vector<std::string> *filtered_fields = nullptr)

Filter frame fields by zeroing out rows or columns in UV coordinates.

When coord_2d is “u”, rows in [lower, upper) are invalidated directly. When coord_2d is “v”, columns in [lower, upper) are invalidated in the destaggered domain and then re-staggered.

Parameters:

  • frame[inout] The lidar frame to filter in place.

  • coord_2d[in] Coordinate axis to filter along: “u” for rows or “v” for columns.

  • lower[in] Start index of the range to invalidate (inclusive).

  • upper[in] End index of the range to invalidate (exclusive).

  • invalid[in] Value assigned to filtered-out pixels. Defaults to 0.

  • filtered_fields[in] Optional list of field names to apply the filter to. If null, all pixel fields are filtered.

Throws:

std::invalid_argument – If coord_2d is not “u” or “v”, or if bounds are out of range.
