Hello @qingwei sun
Thanks for using Microsoft Q&A platform, I think the resource of this image is here - https://zhuanlan.zhihu.com/p/75132106
The technology used in this image is Azure Kinect and Azure Computer vision - https://azure.microsoft.com/en-us/services/cognitive-services/computer-vision/#overview
There is no developed application for you to use directly but a developing direction, unfortunetely, but you need to develop your application to recognize different "size/ style" object so that the appliction can help you count the status.
I hope this helps.
Regards,
Yutong
