I sorted out some basic questions about opencv AI kit.

This article was first published in oakchina.cn

Open source software and hardware OpenCV AI Kit（OAK）.OpenCV Many general algorithms covering image processing and computer vision , It is one of the most powerful research tools , And firmly ranked among developers' favorite AI Tools / Frame top .

1、 Will it be? USA Forbid ？
answer ： Can't , Myriad X Can sell , Slightly lower performance （ Embedded chip 4TOPS）, What is banned is 100+TOPS Chip .

2、opencv Do developers have to spend money ？
answer ： Try to reduce the price of hardware . such as Azure Kinect DK Only the depth function , But to 2400 element . Do depth 、 Artificial intelligence 、 The image processing 、 Lossless scaling 、 Object tracking A series of functions , It only needs 1170 element （OAK-D-LIIE） Welcome to Taobao store ： Pachi Electronics .

3、OAK This hardware , Are there any on the market at present ？
answer ： yes , we have , The original price is OAK-1 1170 element , OAK-D-Lite 1170 element ,OAK-D 1560 element .

4、 and openmv What's the difference ？
answer ： There are differences in speed and depth . OpenMV Only 0.05TOPS, however OAK Yes 4.0TOPS, And artificial intelligence and image processing are better than OpenMV fast 80 times .

5、 How to train a custom model ？
answer ： There are many different tutorials , You can see the tutorial on this link , Open source project , Free pre trained neural network model .

6、 This development board is cpu What is it ？ARM, still Intel？
answer ：Intel Of Modvidius Myriad X.

7、 Where to buy in China ？
answer ：OAK China It is the official general agent in China .

8、1560 block , The production environment is too expensive ？ Not so good Jetson nano Well , What are the advantages of comparison ？
answer ：Jetson Nano Without a binocular camera , You have to buy this camera alone 1000 many , We should also develop our own depth calculation .Realsense Also want to 1500 about , But without neural network acceleration function . In the production environment ,OAK Support customized purchase OAK China's OAK Core board （ Less than 500 element ） And customized camera modules , Design carrier shell , Make your own products .

9、ARM still x86?
answer ：Intel Of Movidius Myriad X, But it can be used as any ARM, Intel, AMD, On any operating system （ As long as it can support OpenCV）.

10、 Hardware open source ？
answer ： Open source , Please look at this link .

11、 Purchase channel ？
answer ： Can be in the above link Buy ,OAK China will sell at home .

12、Nvidia Is it possible to ？
answer ： Can be in Nvidia Run on all boards .

13、 This can run C/C++ Do you ？ Or just support python？
answer ：API Support C++ and Python, also microPython Will also support .

14、OAK What are the specific functions of ？ Is there any more information ？
answer ：

• Neural network computing , Object recognition , Image classification
• 3D Spatial positioning , In depth prediction
• Object tracking
• In depth prediction
• h.264/h.265 code
• The zoom And there are 12MP Sensor pixels It's six times 1080p camera
• Background processing
• Feature tracking
• Expression prediction
• The image processing （ tailoring , The zoom , Format change ）

15、 Can you invoice ？
answer ：Yes （ Contact the customer service of paichi electronic in Taobao store 、 You can invoice ）

16、 Planned rust Language version ？
answer ： Support , There are already developers working on it , also ROS Will also support .

17、 The hardware Schemtatic Will you provide ？
answer ：https://github.com/luxonis/depthai-hardware

18、 Open source software in github obtain ？
answer ：https://github.com/luxonis/depthai and https://docs.luxonis.com/faq/#githubs

19、 stay Google What platform training ？ Can I use it in China ？
answer ： Any support CPU The training platform is OK . Microsoft Azure, Amazon's AWS, Google's Colab, Or local computer .

20、 So general Ubuntu Is that ok ？
answer ： Tolerable ,Ubuntu System 16、18、20 Fine , whatever Linux All of them can , also Mac OS X and Window Fine .

21、 During this period, some opencv The library of , Or did you write some libraries to help write your own training model ？
answer ： Some libraries have been added and open source .

22、 Still intel Of Openvino Platform, right ？ Mainly using their reasoning framework ？
answer ：OpenVINO Used for optimization to make the model run faster .

23、 Very good. Which kits should be installed first in the early stage open champion that will do ？ Before you can run ？
answer ： Very light , It's like OpenCV As convenient as .

24、 There are wechat groups or QQ Group to communicate ？
answer ： There are wechat groups and QQ Group , Please add wechat group first 13951940532 Mr. Zhang
QQ Group please add group number 280844897

25、 Do you support Alipay and WeChat payment? ？
answer ： Supported by , Please contact wechat or Taobao Wangwang

26、Nvidia card Is it any different from you ？
answer ：Nvidia Of Jetson Nano Only 0.472 TOPS, But there are 4.0TOPS, So it's about 8 Times the running speed . And there are embedded 12MP Camera and two 1MP Global shutter depth camera , The power consumption is also smaller, with an average of only 2.5W.
