Description
本創作係涉及一種汽車A柱視覺盲區顯示裝置，尤指一種具有攝影鏡頭裝置，可將受汽車A柱障蔽處的影像由設於車內的顯示器顯示者。 This creation relates to an automobile A-pillar visual blind zone display device, especially a device with a photographic lens, which can display the image of a place obscured by the automobile A-pillar by a display installed in the car.
按，為支撐汽車結構，在擋風玻璃兩側、前後門之間、及後擋風玻璃兩側有三根立柱，分別稱做A、B、C柱；這三組柱子在汽車翻覆時，具有避免變形的保護作用，但卻同時造成駕駛的視線死角。目前新上市的車款中，多半會有感應器，以震動、光線、聲音等方式，警示駕駛盲點內有障礙物；而A柱是車輛擋風玻璃兩側的主要結構，為顧及車體強度多半會設計的較為粗壯，但也因此容易產生死角，左轉彎時尤其嚴重，因此駕駛人都有經驗在駕駛座上，總有一些視線死角必須要非常小心才能夠避開意外，尤其是座位左右兩邊的A柱。 Press, in order to support the car structure, there are three pillars on both sides of the windshield, between the front and rear doors, and on both sides of the rear windshield, which are called A, B, and C pillars; these three groups of pillars have The protective effect of avoiding deformation, but at the same time it causes a blind spot for driving. Currently, most of the new models on the market have sensors that use vibration, light, sound, etc. to warn of obstacles in the driving blind spot; the A-pillar is the main structure on both sides of the vehicle’s windshield, in order to take into account the strength of the car body. Most of the design will be thicker, but it is also prone to blind corners, especially when turning left. Therefore, drivers have experience in the driver's seat. There are always blind corners of sight that must be very careful to avoid accidents, especially on the left and right sides of the seat. A pillars on both sides.
為解決汽車A柱視覺盲區問題，不論學術界或業界都積極研發，期待能解決A柱視覺盲區問題，提高行車安全；其中，據報導美國女學生將車輛A柱視覺盲區景象透過Webcam攝影機取得影像，並在A柱內側裝上特殊布料，利用投影使A柱如同透明的，駕駛可以藉此看到外面的即時影像，解決視線死角的問題。 In order to solve the problem of A-pillar visual blind spots in automobiles, both academia and the industry are actively developing and looking forward to solving the problem of A-pillar visual blind spots and improving driving safety. Among them, it is reported that American female students use the A-pillar visual blind spots to obtain images through Webcam cameras. , And a special fabric is installed on the inside of the A-pillar. The projection is used to make the A-pillar as transparent, so that the driver can see the real-time image outside and solve the problem of blind spots in the line of sight.
然而，上述看似簡易實施的創作，卻存在投影機架設固定問題，眾所周知，每個品牌每種車款其儀表板上方飾板，幾乎都有不同程度幅度，造成投影機安裝上的困難；再者，容易受天候影響如夜間、陰天、下雨天光源較弱時，Webcam攝影機取得之影像畫質不佳，再經過投影時，又再降低其成像畫質，因此，該創作具體實施存有疑義。 However, the above seemingly simple creation has the problem of fixing the projection rack. As we all know, the upper fascia of the dashboard of each car model of each brand has varying degrees of magnitude, which makes the installation of the projector difficult; In addition, it is easily affected by the weather, such as night, cloudy, and rainy days. When the light source is weak, the image quality obtained by the Webcam camera is not good. When it is projected, the image quality is reduced. Therefore, the specific implementation of the creation exists. Doubt.
又，我國2008年台南一中的學生在發明展中，請參閱圖5亦提出利用貼附於A柱之第一鏡面60，透過簡單的角度第二鏡面70調整，便成功的使A柱變為透明，而這項發明也讓他在展覽中拿下金牌；然，日本豐田TOYOTA汽車的新專利，亦採取相同光學的角度原理，利用光線折射的技術，讓駕駛能夠看到A柱後方的景象，進而達到縮小甚至消除盲區的效果。
In addition, the students of Tainan No. 1 High School in China in the invention exhibition in 2008, please refer to Figure 5 and also proposed to use the
惟，利用光線折射的技術，讓駕駛能夠看到A柱後方的景象，看似開發成本低廉，然而幾乎所有車款的A柱都大小不一、幅度不同，成像鏡難以固定，而反射鏡亦容易因車輛震動，導致反射鏡歪斜，效果並不理想。 However, the use of light refraction technology allows the driver to see the scene behind the A-pillar. It seems that the development cost is low. However, the A-pillars of almost all models are of different sizes and amplitudes. It is difficult to fix the imaging lens and the mirror. It is easy to cause the reflector to tilt due to the vibration of the vehicle, and the effect is not ideal.
因此，就算近年盲點偵測技術日益普及，但A柱的盲區問題依然嚴重，而在2014年時Jaguar汽車也曾使用360º全液晶顯影的技術，試圖打造無死角視野，但高昂的成本卻使得這樣的技術難以投產，而目前其他車輛盲區偵測技術主要是利用雷達裝置、視覺原理或視覺處理來達成。基於雷達裝置的盲區偵測技術主要是通過在車輛上布置雷達系統，來偵測周圍障礙物。其優點是偵測的靈敏度高，但缺點也較為明顯，例如無法提供給駕駛員視覺上的直觀訊息、無法區分背景或移動物體，或無法依據運動方向趨勢進行警報判斷，因此可能產生較多不必要的誤報。 Therefore, even if the blind spot detection technology has become more and more popular in recent years, the problem of the blind area of the A-pillar is still serious. In 2014, Jaguar cars also used 360º full LCD development technology to try to create a field of view without blind spots, but the high cost made this The technology is difficult to put into production, and the current blind spot detection technology of other vehicles is mainly achieved by using radar devices, visual principles or visual processing. The blind spot detection technology based on the radar device mainly detects surrounding obstacles by arranging a radar system on the vehicle. Its advantage is high detection sensitivity, but its disadvantages are also obvious. For example, it cannot provide the driver with intuitive information, cannot distinguish background or moving objects, or cannot make alarm judgments based on the direction of movement, so it may cause more problems. Necessary false positives.
有鑑於此，相關業者或學術單位不斷研發相關改良技術，其中，我國專利第I696905號「車輛盲區偵測方法」，主要揭示了：一種車輛盲區偵測方法，適用於一電子裝置耦接配置於一車輛上的一或多個攝影機，該方法包括：在該攝影機所取得的一當前幀畫面中設立捕獲區域，並對進入該捕獲區域的物體進行偵測，將符合捕獲條件的該物體與該物體的位置訊息被加入跟蹤列表中；對在早於該當前幀畫面的一至多個先前幀畫面中加入該跟蹤列表的既存物體進行跟蹤運算以得到該既存物體在該當前幀畫面中的新位置訊息，並根據該既存物體的該新位置訊息與該偵測範圍判定是否繼續將該既存物體保留在該跟蹤列表中；依據該跟蹤列表中保留的所有物體在該當前幀畫面中的位置訊息做出示警判斷。 In view of this, related industries or academic units continue to develop related improved technologies. Among them, the Chinese Patent No. I696905 "Vehicle Blind Spot Detection Method" mainly discloses: a vehicle blind spot detection method, which is suitable for an electronic device to be coupled to One or more cameras on a vehicle, the method includes: setting up a capture area in a current frame image obtained by the camera, detecting an object entering the capture area, and comparing the object that meets the capture condition with the The position information of the object is added to the tracking list; the tracking operation is performed on the existing objects that are added to the tracking list in one or more previous frames earlier than the current frame to obtain the new position of the existing object in the current frame Information, and determine whether to keep the existing object in the tracking list based on the new position information of the existing object and the detection range; do it based on the position information of all the objects retained in the tracking list in the current frame Show warning judgment.
然而，上述習知技術固然可達到示警判斷要求，然而，攝影機所取得的一當前幀畫面中設立捕獲區域，並對進入該捕獲區域的物體進行偵測之技術，不僅需要配置高度運算計算機功能，且需具有以人工編寫的電腦程式，去模擬出人類的「智慧」行為，其中包含模擬人類感官的「聽音辨讀、視覺辨識」、大腦的「推理決策、理解學習」、動作類的「移動、動作控制」等邏輯運算功能，亦即所謂人工智慧(Artificial Intelligence)，如此開發成本龐大，維護成本高昂，具有不易商業化的缺點。 However, the above-mentioned conventional technology can certainly meet the requirements of warning judgment. However, the technology of setting up a capture area in a current frame image obtained by a camera and detecting objects entering the capture area requires not only the configuration of a high-level computing computer function, but also And you need to have a computer program written by hand to simulate human "smart" behaviors, including "listening and reading, visual recognition" that simulates human senses, "reasoning and decision-making, understanding and learning" of the brain, and action-related " Logic calculation functions such as movement and motion control, also known as artificial intelligence, have huge development costs and high maintenance costs, and have the disadvantage of not being easy to commercialize.
又如，我國第M562412號「車輛之環景偵測系統」，主要揭示：一種車輛之環景偵測系統，其設置複數個影像感測裝置於車輛之周圍進行取像偵測，該些影像感測裝置包含一影像擷取元件、一運算模組以及一警示模組，影像擷取元件擷取車輛外圍之影像，由運算模組偵測影像之至少一移動物產生一偵測訊號與至少一追蹤標記。爾後警示模組接收偵測 訊號，判斷移動物接近車輛時，產生、傳輸一警示訊號於至少一警示元件，以發出警示效果(如聲、光)。另外，該些影像感測裝置將取得之影像傳輸至一影像輸出裝置進行影像拼接，爾後顯示一環景影像和追蹤標記供駕駛者獲取車輛外部之路況。 For another example, my country's No. M562412 "Vehicle Surrounding Detection System" mainly reveals: a vehicle's surrounding view detection system, which is equipped with a plurality of image sensing devices around the vehicle to detect images, these images The sensing device includes an image capturing element, an arithmetic module, and a warning module. The image capturing element captures an image of the periphery of the vehicle. The arithmetic module detects at least one moving object in the image to generate a detection signal and at least One tracking mark. Later, the warning module receives detection The signal is used to determine that when a moving object approaches the vehicle, a warning signal is generated and transmitted to at least one warning element to emit a warning effect (such as sound and light). In addition, the image sensing devices transmit the acquired images to an image output device for image splicing, and then display a surrounding scene image and tracking marks for the driver to obtain the road conditions outside the vehicle.
上述習知技術，雖然可以達到警示視野盲區的難題，然而，係將影像傳輸至音響處螢幕，駕駛人必須一邊觀看螢幕一邊駕駛車輛，如此其實並未增加車輛安全係數，開發成本龐大，維護成本高昂，具有不易商業化，且影像傳輸容易受到天候影響白天、黑夜、晴天、雨天不同而產生過度曝光、曝光不足、失真的缺點。 Although the above-mentioned conventional technology can reach the problem of warning blind spots, the driver must drive the vehicle while watching the screen while transmitting the image to the audio screen. This does not actually increase the safety factor of the vehicle. The development cost is huge, and the maintenance cost is huge. It is expensive and has the disadvantages that it is not easy to commercialize, and the image transmission is easily affected by the weather, resulting in overexposure, underexposure, and distortion due to differences in day, night, sunny, and rainy days.
為改善汽車A柱障蔽所帶來的不便以及危險，本創作的目的在於，利用攝影鏡頭裝置配合可撓性顯示器的技術手段，將障蔽處的影像顯示於可撓性顯示器，藉此供車內的駕駛人觀看以達到視野無死角的功效。 In order to improve the inconvenience and danger caused by the car A-pillar barrier, the purpose of this creation is to use the technical means of a photographic lens device with a flexible display to display the image of the barrier on the flexible display for use in the car. The driver can watch to achieve the effect of no blind spots in the field of vision.
為達到上述目的，本創作人多方思索研究，終得以低廉成本與結構完成本創作之裝置。 In order to achieve the above-mentioned purpose, the creator of this creative thought and research in many ways, and finally was able to complete the device of this creation at a low cost and structure.
