技術說明

本發明係以圖像層次訊息為基礎之小動物三維運動軌跡追蹤及姿態重建法；以解析多種深度圖成像裝置之圖像層次訊息追蹤小動物之立體空間運動路徑，並以動態三維模型重建該動物之姿態以分析該動物之行為。傳統動物運動量分析係採人力、特殊感測裝置或攝影機記錄待測物位置，並以人力或自動化演算法標定之。人力分析耗時、成本高昂且缺乏客觀性；而本發明之三維運動量重建方法可在不必添增任何標籤於目標動物情況下，精確量測立體特徵複雜，具有豐富立體形狀變化行為之目標物，並可重建目標物三維空間之姿態細節，提供完整行為資訊。 This invention is a depth map-based approach for three-dimensional locomotion tracking and pose reconstruction in small animals, which analyzes depth information from various depth map rendering device to track three-dimensional path of small animal without any physical tags, and dynamically reconstruct animal pose in three-dimensional model. Manual recording suffers from subjectivity and high labor cost. Sensor arrays are relatively reliable but expensive, and the resolution is low. However, this invention is a new approach of behavioral measurement in small animals and reconstruction in three-dimensional model including its moving track without constraints of ambient light conditions, contrast, invasive labeling tags, and provides advantages in robustness, rapidity, reliability, and resolution of locomotion analysis to previous methods.
