quick_depth_handeye_calibration

Usually, we solve calibration problem by AX=XB.Acutally, this is too trouble with many steps. This repository introduces a quite simple but efficient method for handeye calibration with a quite high precision.

you can run: calibrationinteractive.launch image And move point cloud on the model,like this: image

Although it is simple, the final test precision is higher than traditional calibration methods: image

If anyone wants to change the initial pose, you can change it over here: image

本项目可以自由添加多个需要调节的link,只需要在roslaunch里面增加相应的node即可,但ns命名需要不一样,比如这个:

Improvement: The method above

第三类方法(通过gazebo进行点云建模,然后再进行icp标定): gazebo建模方法(这里用的是iiwa的,本质就是搭建几个gazebo的kinect拼接即可)gazebo的环境导出来可以来替换calibration.world 注意,如果是多相机的化这里的calibration.world里面的frameName和pointCloudTopicName等等都需要换个名字。具体而言,我们这边其实把world这部分提供在这里了,也就是added.world,对于任意机器人,只要在其本身的world里面把我们这个added.world加进去就行: Screenshot from 2021-05-28 21-03-14 还有一个需要注意的是,gazebo建模里面,也就是world里面相机的link并不会发布,所以,这里需要额外发布link。所以,我们这边写了一个程序,专门将这些点云进行发布,同时进行拼接,下面蓝色部分即为点云部分: Screenshot from 2021-05-29 11-44-36 (最近忙,这部分毕业后再写)
