【講座信息】

  當下,有三個“支柱(pillars)”因素決定著導航技術的性能或實用性,即成本、精度和連續性。導航是一門長盛不衰的技術,數千年來,持續吸引著人們前赴后繼地研究。毫無疑問,全球導航衛星系統(Global Navigation Satellite System, GNSS)主導著目前的定位導航市場。GNSS除了能夠提供全球性的服務外,還滿足了上述與成本、精度有關的兩種“支柱”條件。換句話說,它能以較低成本的代價,提供各種不同精度要求范圍內的導航定位信息。另外,該技術還可以滿足高便攜性和低功耗的需求,非常適合與其他各類傳感器、通信鏈接以及數據庫進行融合。

  盡管GNSS優勢眾多,但它并非適用于任何環境下的導航任務,從而導致其無法滿足“連續性”的“支柱”要求。因此,為了進一步地發展導航技術,急需發展一種替代型的導航定位系統。目前,導航系統的市場也在朝著精確的、連續的、易購的方向穩步發展。毋庸置疑,在系統成本和體積的制約下,汽車、便攜設備(如智能手機)、自動控制系統(如自動駕駛、無人機和農業機械系統)的制造商得以研究和開發下一代低成本、小型化的導航系統,從而滿足快速發展的自動駕駛車輛及位置服務市場的需求。此次報告將著眼于自動駕駛車輛,介紹其所用傳感器的最新情況及未來發展趨勢,其中包括傳感器的可能性、限制性以及各種不同的設計方案。此次報告的重點,還將集中于如何利用傳感器和相關技術,實現隨處的、全天時的、全天候的輕量型自動駕駛車輛導航系統。最后,報告將通過不同的實驗/應用,演示一些目前已開發的及未來可能出現的導航系統的精度性能。

 

There are three ‘pillars’ that define the performance or usefulness of a navigation technologies – cost, accuracy, and continuity. Navigation is a field that has been fascinating humankind for thousands of years and these pillars have been evolving with new technological advancements.  The current market in positioning and navigation is clearly dominated by GNSS. Besides being globally available, it meets two important pillars: accuracy and cost by providing the whole range of navigation accuracies at very low cost. It is also highly portable, has low power consumption, and is well suited for integration with other sensors, communication links, and databases.

At this point in the development of navigation technology, the need for alternative positioning systems only arises because GNSS does meet the continuity pillar as it does not work in all environments. Furthermore, there has been a constant market push to develop navigation systems that are accurate, continuous and easy to afford. Needless to say, that cost, and space constraints are currently driving manufacturers of cars, portable devices (e.g. smartphones), and autonomous systems (e.g. self-driving, drones and agriculture machine systems) systems to investigate and develop next generation of low cost and small size navigation systems to meet the fast-growing autonomous vehicles and location services market demands. This presentation will provide a state of the art and future trends of sensors used for navigation of autonomous vehicles: possibilities, limitations and various design approaches.  Emphasis will be on sensors and technologies that can navigate autonomous vehicles everywhere and at any time independent of weather and light conditions. Some of the current developed and possible future system’s accuracy performance will be demonstrated through different implementations/applications.
