kandi X-RAY | yamlbeans Summary
YamlBeans makes it easy to serialize and deserialize Java object graphs to and from YAML, a human-friendly data format. Replace XML and properties files with YAML for more expressive power (lists, maps, anchors, etc) and easier hand-editing.

QUESTION
I'm trying to load / save OpenCV calibration data in YAML format using the official OpenCV Java bindings. I am aware OpenCV (c++ version at least) can serialize to XML and JSON but I would like to support older YAML calibration files.
A calibration file looks like this:
...ANSWER
Answered 2020-Apr-28 at 06:11Have you looked at Jackson library ? It allows mapping JSON/Yaml content to Java POJOs.
I've made a little example which solves two of your problems:
- swapping opencv-matrix with MatYAML string
- manually casting HashMap values
However, for yaml version directive, as it looks like it is not valid Yaml, I'm not sure how to handle it. In my example, I've removed it manually before-hand. Surely, a better solution can be found, but I don't know it.
EDIT2: For the matrix object, I've made a dumb POJO, used internally by Jackson to read brut YAML. Then, I've added a conversion layer (see @JsonSerialize and @JsonDeserialize anotations on OpenCVConfig class) to convert this simple POJO to specialized OpenCV matrix. Jackson offers various technics (streaming, custom converters/deserializers, guiding annotations, etc.) of mapping, so you can explore its capabilities to find the solution that fits best to you need.
So, to make the example work, you'll need two dependencies (given here in maven format):

Install yamlbeans
You can use yamlbeans like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the yamlbeans component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
