rosbagwriter

Create and write logs to rosbag log file

Since R2021b

Description

Use the rosbagwriter object to create a rosbag log file and write logs to the bag file. Each log contains a topic, its corresponding timestamp, and a ROS message.

Note

The rosbagwriter object locks the created bag file for use, it is necessary to delete and clear the rosbagwriter object in order to use the bag file with a reader or perform other operations.

Creation

Syntax

bagwriter = rosbagwriter(filepath)

bagwriter = rosbagwriter(___,Name,Value)

Description

bagwriter = rosbagwriter(filepath) creates a rosbag log file in the location specified by path and returns the corresponding rosbagwriter object.

If you do not specify the name of the bag file in the filepath, the object assigns the current timestamp as the file name. If the folders you specify in filepath are not present in the directory, the object creates them and places the bag file accordingly. The filepath input argument sets the FilePath property.

example

bagwriter = rosbagwriter(___,Name,Value) sets the Compression and ChunkSize properties using name-value arguments. Use this syntax with the input argument in the previous syntax.

Properties

expand all

`FilePath` — Path to rosbag file
Read-only: character vector

This property is read-only.

Path to the rosbag file, specified as a character vector.

Data Types: char

`StartTime` — Timestamp of first message written to bag file
Read-only: scalar

This property is read-only.

Timestamp of the first message written to the bag file, specified as a scalar in seconds.

Data Types: double

`EndTime` — Timestamp of last message written to bag file
Read-only: scalar

This property is read-only.

Timestamp of the last message written to the bag file, specified as a scalar in seconds.

Data Types: double

`NumMessages` — Number of messages written to bag file
Read-only: scalar

This property is read-only.

Number of messages written to the bag file, specified as a scalar.

Data Types: double

`Compression` — Compression format of message chunks
`"uncompressed"` (default) | `"bz2"` | `"lz4"`

Compression format of the message chunks, specified as "bz2", "lz4", or "uncompressed".

Example: "Compression","lz4"

Data Types: char | string

`ChunkSize` — Size of each message chunk
`786432` (default) | nonzero positive integer

Size of each message chunk, specified as a nonzero positive integer in bytes. The value specify the buffer within the bag file object. Reducing this value results in more writes to disk.

Example: "ChunkSize",819200

Data Types: double

`FileSize` — Current bag file size
Read-only: nonnegative integer

This property is read-only.

Current bag file size, specified as a nonnegative integer in bytes.

Data Types: double

Object Functions

Create a rosbagreader object of all the messages in the rosbag log file.

reader = rosbagreader('path_record.bag');

Select all the messages related to the topic '/circle'.

bagSelCircle = select(reader,'Topic','/circle');

Retrieve the list of timestamps from the topic.

timeStamps = bagSelCircle.MessageList.Time;

Retrieve the messages in the selection as a cell array.

messages = readMessages(bagSelCircle);

Create a rosbagwriter object to write the messages to a new rosbag file.

circleWriter = rosbagwriter('circular_path_record.bag');

Write all the messages related to the topic '/circle' to the new rosbag file.

write(circleWriter,'/circle',timeStamps,messages);

Remove the rosbagwriter object from memory and clear the associated object.

delete(circleWriter)
clear circleWriter

Retrieve all the information from the new rosbag log file.

Load the new rosbag log file.

readerCircle = rosbagreader('circular_path_record.bag');

Create a time series for the coordinates.

tsCircle = timeseries(readerCircle,'X','Y');

Plot the coordinates.

plot(tsCircle.Data(:,1),tsCircle.Data(:,2))
