ob_filter* ob_create_pointcloud_filter ( ob_error ** error )

Create PointCloud Filter.

Parameters

[out] error Log error messages

Returns: filter pointcloud_filter object

void ob_pointcloud_filter_set_camera_param	(	ob_filter *	filter,
		ob_camera_param	param,
		ob_error **	error
	)

PointCloud Filter device camera parameters.

Parameters

[in]	filter	pointcloud_filter object
[in]	param	Camera parameters
[out]	error	Log error messages

void ob_pointcloud_filter_set_point_format	(	ob_filter *	filter,
		ob_format	type,
		ob_error **	error
	)

Set point cloud type parameters.

Parameters

[in]	filter	pointcloud_filter object
[in]	type	Point cloud type: depth point cloud or RGBD point cloud
[out]	error	Log error messages

void ob_pointcloud_filter_set_frame_align_state	(	ob_filter *	filter,
		bool	state,
		ob_error **	error
	)

Set the alignment state of the frames that will be input to produce the point cloud.

Parameters

[in]	filter	pointcloud_filter object
[in]	state	Alignment status, True: aligned; False: unaligned
[out]	error	Log error messages

void ob_pointcloud_filter_set_position_data_scale	(	ob_filter *	filter,
		float	scale,
		ob_error **	error
	)

Set the point cloud data scaling factor.

Attention: Calling this function to set the scale will change the point coordinate scaling factor of the output point cloud frame: posScale = posScale / scale.The point coordinate scaling factor for the output point cloud frame can be obtained via ob_points_frame_get_position_value_scale function

Parameters

[in]	filter	object
[in]	scale	Set the point cloud coordinate data zoom factor
[out]	error	Log error messages

void ob_pointcloud_filter_set_color_data_normalization	(	ob_filter *	filter,
		bool	state,
		ob_error **	error
	)

Set point cloud color data normalization.

Parameters

[in]	filter	object
[in]	state	Sets whether the point cloud color data is normalized
[out]	error	Log error messages

ob_filter* ob_create_format_convert_filter ( ob_error ** error )

Create FormatConvet Filter.

Parameters

[out] error Log error messages

Returns: filter format_convert object

void ob_format_convert_filter_set_format	(	ob_filter *	filter,
		ob_convert_format	type,
		ob_error **	error
	)

Set the type of format conversion.

Parameters

[in]	filter	formatconvet_filter object
[in]	type	Format conversion type
[out]	error	Log error messages

ob_filter* ob_create_compression_filter ( ob_error ** error )

Parameters

[in]	filter	compression_filter object
[in]	mode	Compression mode OB_COMPRESSION_LOSSLESS or OB_COMPRESSION_LOSSY
[in]	params	Compression params, struct ob_compression_params, when mode is OB_COMPRESSION_LOSSLESS, params is NULL
[out]	error	Log error messages

ob_filter* ob_create_decompression_filter ( ob_error ** error )

Returns: filter decompression Filter object

void ob_filter_reset	(	ob_filter *	filter,
		ob_error **	error
	)

Filter reset, cache clear, state reset. If the asynchronous interface is used, the processing thread will also be stopped and the pending cache frames will be cleared.

Parameters

[in]	filter	filter object
[out]	error	Log error messages

ob_frame* ob_filter_process	(	ob_filter *	filter,
		ob_frame *	frame,

Returns: ob_frame The frame object processed by the filter

void ob_filter_set_callback	(	ob_filter *	filter,
		ob_filter_callback	callback,
		void *	user_data,
		ob_error **	error
	)

Filter Set the processing result callback function (asynchronous callback interface)

Parameters

[in]	filter	filter object
[in]	callback
[in]	user_data	Arbitrary user data pointer can be passed in and returned from the callback
[out]	error	Log error messages

void ob_filter_push_frame	(	ob_filter *	filter,
		ob_frame *	frame,
		ob_error **	error
	)

filter Push the frame into the pending cache (asynchronous callback interface)

Parameters

[out]	error	Log error messages

void ob_delete_filter	(	ob_filter *	filter,
		ob_error **	error
	)

Delete Filter.

Parameters
