An example of a specific ability to demonstrate visual ability is Cityscape's list of achievements. The latter is a data set used to evaluate visual algorithms, which can test the performance of the algorithm in the semantic understanding of urban scenes. In October of this year, the University of Science and Technology News won the first place in the automatic driving scene segmentation task, mainly using a technology called "hierarchical segmentation".
For a long time, Keda Xunfei has indirectly provided services to car companies through the car system suppliers in the front-loading field of vehicles. The business only focuses on intelligent voice technology.
However, at the 2016 annual conference of the University of Science and Technology, we saw a car-connected system "flying fish assistant." HKUST News officially announced that it will package a complete set of hardware, software and data services for the vehicle system in the future, and the role will be transformed into TSP.
After a year, the flying fish was upgraded to version 2.0 and a clearer and more complete product architecture was formed. Moreover, we found that in addition to the core intelligent voice interaction, the University of Science and Technology began to make vision.

What is the update of Flying Fish 2.0?
On the 1.0 version of Flying Fish, the entire interactive experience is more natural. When people talk to the car, the car can remember the context and understand the meaning of each one. You can call navigation, music, make calls, etc. without having to wake up multiple times, or interrupt the car as you speak.
At the site of this year's annual meeting, the Flying Fish 2.0 version was upgraded. Xie Xinzhen, deputy general manager of the Automotive Division of the University of Science and Technology, told reporters that the display of Flying Fish 1.0 last year is still a future plan, but this year's version 2.0 is already a product that can be landed.
You can see a few highlights that were not available from the video above:
1. Know who to listen to. The new version of the system knows which direction of sound to collect, and after the driver is locked in the position of the wake-up word, the sound of the passenger seat will not appear to be "grabbing the wheat." To achieve this, the main task is to upgrade the microphone array and software algorithms.
2. Connect to the background account system. Flying Fish 2.0 can "actively serve" after waking up. It will remind you that today is the wife's birthday, recommend the restaurant that his wife likes, recommend the movie you like and then buy the ticket. The system and the individual are more deeply bound.
3. Access to the vehicle bus system. In 1.0, the system can only control the infotainment functions such as music, navigation, and telephone with voice. In version 2.0, we can use voice control to switch the sunroof, adjust the air conditioning temperature and the functions that have little impact on driving safety.
In addition to the first point is the update of intelligent voice technology, the latter two are all integrated with the combination of soft and hard services, the voice has the opportunity to have more connections with the car and people.
Of course, the latter two also represent a choice. A more personalized service means the development of the right to use personal data, which is the choice that users face. A better understanding of the car means the opening of vehicle data, which is the choice faced by the OEM.
Wake up your eyes
In addition to intelligent voice interaction, image recognition also finds opportunities to function in car scenes.
Frankly speaking, when seeing the notice before the meeting, the reporter thought that visual technology would be more used in driver identification. Because Zhao Yanjun, director of R&D at HKUST, once said that AIUI did not use speech as the only way to interact, but imagined it as a combination of face, body tracking, gestures, infrared, etc. An integrated human-computer interaction solution."
Therefore, when Keda Xunfei said that he would use the camera's eyes to look outside the car, the reporter was still somewhat surprised.
The first application scenario for vision will be parking. In the case of a clear parking line, the parking camera can be used to observe the external situation. When finding a suitable parking space, the user can be reminded to play the steering wheel in an interactive manner to assist the vehicle to enter the garage. When there is no parking line, the driver can also draw a parking position on the screen and the system will park the car in the library. Of course, it can be seen that in the initial version, there is no content related to the vehicle control level.
At present, the visual part is still promoted by the research institute of Keda Xunfei. The selected parking application is also a relatively simple scene. In response to the question "what is the advantage of the company that specializes in vision, what is the advantage of the University of Science and Technology", Xie Xinzhen, deputy general manager of the automotive business department, mentioned the accumulation of the science and technology of the University of Science and Technology. He believes that speech has a higher requirement for signal coherence, and it is easier to make speech across the image.
An example of a specific ability to demonstrate visual ability is Cityscape's list of achievements. The latter is a data set used to evaluate visual algorithms, which can test the performance of the algorithm in the semantic understanding of urban scenes. In October of this year, the University of Science and Technology News won the first place in the automatic driving scene segmentation task, mainly using a technology called "hierarchical segmentation".
The data set test scores can reflect the algorithmic ability of HKUST. However, in practical applications, the algorithm of HKUST is faced with two aspects of embedded platform and real-time. Xie Xinzhen said that the advantage of Keda Xunfei lies in the engineering optimization ability. The 360 ​​look-around algorithm is mainly composed of stitching and fisheye correction. At present, it has been loaded on the CPU and GPU, and the running is smoother.
The University of Science and Technology flies to do visual, which means that the understanding of the insiders extends to the understanding of the environment outside the car.
Liu Junfeng, general manager of the Flying Motors Division of the University of Science and Technology, mentioned in the release of Flying Fish 2.0 that in the future, the two parts of understanding and understanding the environment will be completed together, and a brain (flying fish AIUI) will be used to connect the hearing and the mouth (the flying fish dialogue engine). Eyes (flying fish box), multi-dimensional input, and finally the analysis and processing of data in the background (Flying Fish Data Workshop).
Technology and application for two-wheel drive
Liu Qingfeng, chairman of the board of directors of Science and Technology, and Wu Xiaoru, the president of the company, mentioned one sentence on the day of the conference. Artificial intelligence is a two-wheel drive technology and application. By collecting data training algorithms in the application scene through landing, you can hone better technology.
The Flying Fish 2.0 system includes the flying fish dialogue engine, the flying fish AIUI, the flying fish box, the flying fish data workshop, etc., all of which are products for the vehicle end application.
In order to land products at the car end, the University of Science and Technology has gradually added to the lack of car system. According to Xie Xinzhen, the Science and Technology Department of the University of Science and Technology has reached the scale of 400 people this year, mainly including dialogue engine, big data analysis and software and hardware integration. Among them, the number of employees with soft and hard integration is the highest, nearly half of the total number.
In addition to using a large number of talent reserves to better understand the in-vehicle hardware and software, the core intelligent voice, the University of Science and Technology is also addressing some key issues. Xie Xinzhen said that at present, the accuracy of speech recognition of Mandarin University in the car environment is 98%. In addition to continuing to improve dialect recognition, it will also overcome the bad speech recognition effect in some car environments.
For the current productization situation, Liu Junfeng disclosed a set of numbers - Xunfei's products have covered 200 models, and the annual shipments exceeded 2 million sets, accumulating pre-loading capacity of 10 million.
This year, HKUST has successively signed cooperation frameworks with a number of OEMs including BAIC, GAC, Changan and Chery, covering intelligent voice technology, vehicle intelligence and smart car networking platforms. Xie Xinzhen also revealed that based on the Flying Fish 2.0 system, the cooperation between the University of Science and Technology and the OEM has been carried out for 3-4 months, of which the visual aspect will be 360.
Limited by the shipping cycle and update frequency of the front-end products, the University of Science and Technology has also launched a small flying fish. Xie Xinzhen said that the biggest advantage of Xiaofeiyu is that the iteration speed will be faster and there will be a new function every two weeks. However, the University of Science and Technology will still put more resources and energy into the front, because the front-loading has the opportunity to combine the system and the car to produce more functions.
summaryFrom the small point of in-vehicle intelligent voice, Keda Xunfei provides a closed-loop solution for future smart cars along the understanding and understanding of the two axes of the car. At present, the advantage of the University of Science and Technology is still in the voice, the accumulation of car vision is still relatively early, and finally the vision and voice can not be well integrated, but also waiting for cooperation to hatch a landing product.

Vertical or Straight Female Header Orientation
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.
Right-Angle Female Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).
Each of these pin-types have different applications that fit with their specific configuration.
PCB Connector Stacking
Profile Above PCB
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.
Elevated Sockets/Female Headers
Elevated Sockets aka Stacked sockets/receptacles or Mezzanine are simply stacked female headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
Choosing this type of stacking configuration promotes the following benefits:
Connector Isolation - the contacts are shrouded preventing cable connection mishaps and good guidance for the mating header connectors.
For off-the-shelf wireless PCB module, stacking height is optimized with elevated sockets.
Offers superior strength and rigidity.
Polarisation prevents users from inverted insertion.
Single, Dual or Multiple Number of Rows
For a 1.0mm straight or vertical female header, the standard number of rows that Antenk offers ranges from 1 to 2 rows. However, customization can be available if 3 ,4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.
Pin Material
The pins of the connector attached to the board have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
Custom 1.0mm Pitch Female Headers
Customizable 1.0 mm pitch female headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.
Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.
