dc.description.abstract | 由於全球節約醫療費用的趨勢下,並考慮病患每日至醫院接受治療有其一定的難度。因此,本研究希望發展出一套彩色物件追蹤系統來幫助患者在家便可方便地進行復健醫療。
本研究提出彩色的肢體動作追蹤演算法,在前方的螢幕上看見自己的影像,利用不同顏色的標籤物,附著在關節上,同時利用攝影機擷取動作的畫面,進而辨識肢體動作。此套以居家復健應用為主的影像式動作追蹤系統必須同時擁有足夠的實用性、合理的價格、面積小以及即時處理的特性。本系統發展主要以Altera Cyclone II FPGA為核心控制器,發展一個影像處理系統的硬體部分,利用低成本CMOS Sensor 做影像擷取,再將Bayer pattern圖素轉換RGB彩色像素格式,影像的擷取處理及傳送需要龐大的運算量,為了實現即時影像資料儲存,則採用不斷寫入FIFO來儲存入SDRAM控制機制,再將影像資料讀出FIFO的硬體模組,再用彩色目標物分離演算法擷取特徵物,加上所設計的虛擬動畫配合彩色影像動態物件追蹤達到虛擬實境的效果。 實驗過程中,手臂貼的標籤會隨著觸及遊戲中墜落的圓球而計分,所進行的影像回饋遊戲包含圓球自由墜落與隨機飄動的模式,可簡單的分辨出不同程度的受試者在手臂伸展能力上的差異,並統計出本系統在一般正常受測者量測的數據範圍,以利於日後臨床實驗評估的參考依據。 本FPGA所開發的虛擬實境之復健系統,發展簡單原理的色彩動態物件追蹤演算法,以達到最節約gates使用量實現,彈性的數位技術設計功能朝著最能符合上肢復健功能的需求,因為FPGA是純硬體電路的技術,在系統體積簡化下,不僅節約電力的消耗,使系統更適合於居家復健開發上的實現。 | zh_TW |
dc.description.abstract | Because of economizing on the hospitalization cost in the world, we consider that it is difficult for the patient to receive treatment to the hospital every day. We have developed a color-based motion tracking system to be applied for home-based rehabilitation.
In this study a color-based tracking algorithm for real time capturing human motion is proposed. The image is displayed in the front of the screen. Several different color belts are wrapped around the joints of upper limb and their motions are tracked by web video camera. This color-based motion tracking system must have enough practicability, reasonable price, small area and real-time processing for most users. The core of the system is developed an image processing hardware by using Altera Cyclone II FPGA as a core controller. The low cost CMOS Sensor is used to capture image and to transform Bayer pattern into the original RGB image. The image acquisition and transmission need a powerful computing capability. In order to implement it in real-time, these image data in storage module are constantly written to FIFO of the control module of SDRAM and read out from the FIFO of SDRAM. The algorithms can separate the colored goal to reach motion tracking. The integration of virtual motion pictures and the color based motion tracking are used for the virtual reality. In this experiment, the label that the arm is stuck will score as touch the light ball falling in the game, The images carried on feedback the game, include the light ball fall freely and fall with the way of waving at random. Experimenters in various degree spread difference arm functions. This system counts the data range of these experimenters. In order to benefit the reference basis that the clinical experiment will be assessed in the future. Rehabilitation system that is in the virtual reality is realized with FPGA to develop. The color-based motion algorithm is developed by a simple principle of motion tracking. Realize that saves the consumption of gates most. The elastic digit technical design function, it is the goal to accord with the rehabilitation of upper extremities. Because of FPGA is a technological pure circuit of hardware, under the circumstances that the volume of the system is simplified, not merely economizes the consumption of the electricity. We have made the system suited to be applied to home-based rehabilitation. | en |
