Taipei International Symposium on photoelectric week watch three - Smart unmanned vehicle and driver assistance system trend

Taipei International Optoelectronics week in June 14th to 16 in Taipei Nangang Exhibition Center launched warmly, Photoelectric Technology Industry Association (PIDA) since 1984, the first to do so far with the introduction of new technology, to assist niche industry and promote the forward-looking technology and promote the cooperation between production and teaching purposes, thirty years with the technology industry growth, Taiwan in Chinese founded the first science and technology professional exhibition units, the organizer is this.

In the seminar series, the organizers carefully arrange various technical seminars, can be divided into ITO vehicle photoelectric, photoelectric, prospective academic, flat panel display, optical communication, LED, precision optics, nanotechnology, solar photovoltaic plants, factories, biophotonics, products and business tables, each time 6/14-6/16 a total of three days respectively from various fields of expertise and advanced analytical technology and new technology introduction.

Photo exhibition - the wisdom of unmanned vehicle and driver assistance system trend with 2017 smart car

360 panorama active safety system visual and millimeter wave radar fusion application issues, RoyalTek international general manager Chen Junyan said that if we can achieve automatic driving auxiliary system of the third stage, will be driven by the overall market demand, the products have been imported products on the bus, bus around the accurate measurement and correction. At present, AVM 2D products and 3D products, this product is suitable for the development of automotive OEM customers.

The EU will 24GHz RADAR Bands spectrum as millimeter wave radar, using Dingtian four in one BSD radar technology to collect data, used in reversing radar market, as a warning and reminder function.

The automatic driver assistance system, the main use of radar or LiDAR and camera lens. At present in the distance and accuracy, the camera lens is greater than the effect of radar and LiDAR; 3D analytic object, with the function of LiDAR is the best way. In addition, the three kinds of technology, the advantages and disadvantages of each with each other, if the integration of the three technologies, it can achieve the effect and function of relative optimization.

Professor Lin Shengdi, Department of electronic engineering National Chiao Tung University full range ToF technology. ToF is the abbreviation of Flight Time of, literally fly to the target location, through continuous transmission of optical pulses, and then use the sensor to receive the return light from the object, by detecting the transmitting and receiving pulse flight time to target distance. The other concept is a continuous wave (Continuous wave) way.

If you want to improve the flight ranging accuracy, can strengthen the power of infrared laser or improve the sensitivity of Detector. The sensitivity of Detector enhances the benefits of cost reduction. By using LiDAR automatic driving assistance system in the car, the optical transmitter in the infrared laser, and Detector by CCD, APD, SPAD (single photon avalanche diodes), more than Detector each have advantages and disadvantages, but SPAD can achieve better imaging performance. Taking Toyota LiDAR as an example, using the infrared laser collocation SPAD.
