Description
本揭露書是有關於一種生物檢體(bio-specimen)採檢系統及其採檢方法與應用,特別關於一種自動化的生物檢體採檢系統及其採檢方法與應用。 This disclosure is about a bio-specimen collection and inspection system, its collection and inspection method and application, especially an automated bio-specimen collection and inspection system and its collection and inspection method and application.
隨著新型冠狀肺炎(COVID-19)和其他呼吸道疾病的擴散,為了找出確診的受感染者,醫護人員需要先對疑似被感染的受檢者進行採檢,若經檢驗為確診案例方能進行通報、治療與追蹤。呼吸道疾病的檢體採檢方式,一般都是由全身穿著防護衣的醫護人員徒手對受檢者進行採檢。 With the spread of novel coronavirus pneumonia (COVID-19) and other respiratory diseases, in order to find out the confirmed infected person, medical staff need to first take the suspected infected person for inspection. Reporting, treatment and tracking. For respiratory diseases, the examination methods are generally conducted by medical staff wearing protective clothing to examine the subjects with bare hands.
然而,醫護人員和受檢者面對面的操作方式,容易增加醫護人員在採檢時遭受感染的風險。目前已採用安全檢測亭或透明壓克力擋板,將醫護人員與受檢者隔離以降低醫護人員的採檢風險。然而,以人力進行採檢操作,在疑似個案大量出現時,對於醫護人員的 人力及時間仍是一大耗費。將採檢操作自動化、避免使用人力,已成為該技術領域中一個熱門的課題。 However, the face-to-face operation between medical staff and subjects easily increases the risk of infection for medical staff during testing. At present, safety testing kiosks or transparent acrylic baffles have been used to isolate medical staff from subjects to reduce the risk of medical staff sampling. However, when a large number of suspected cases appear, the inspection operation is carried out manually. Manpower and time are still a big waste. Automating the collection and inspection operation and avoiding the use of manpower has become a hot topic in this technical field.
然而,採檢位置通常位於生物的身體腔室中,若要將採檢操作自動化,勢必要得知採檢部位的立體空間資訊,方能將採檢裝置,例如採檢棒(swab)伸入採檢部位。雖然現有技術已能使用例如,電腦斷層(Computed Tomography,CT)掃瞄、磁性共振(Magnetic Resonance Imaging,MRI)掃瞄和X射線(X-Ray Imaging)影像等儀器設備,來建構採檢部位的立體空間。但這些儀器設備不僅昂貴、量體太大、操作複雜,且有輻射暴露的風險。 However, the sampling location is usually located in the body chamber of the living being. To automate the sampling operation, it is necessary to know the three-dimensional spatial information of the sampling site, so that the sampling device, such as the swab, can be inserted into the Inspection site. Although the existing technology has been able to use, for example, Computed Tomography (CT) scanning, Magnetic Resonance Imaging (MRI) scanning and X-ray (X-Ray Imaging) imaging and other equipment, to construct the detection site three-dimensional space. But these instruments are not only expensive, bulky, and complicated to operate, but also carry the risk of radiation exposure.
雖然目前的立體光學攝影技術已相當成熟,可用於直接擷取採檢部位的立體影像。但立體光學攝影的鏡頭尺寸較大,並不適於伸入任何身體腔室中,尺寸過大的鏡頭極有可能妨礙採檢操作的進行。 Although the current stereo optical photography technology is quite mature, it can be used to directly capture the stereo image of the inspection site. However, the lens size of stereo optical photography is large, and it is not suitable for extending into any body cavity, and the lens with too large size is very likely to hinder the inspection operation.
另外,為有效應用醫療人力資源,各界極力尋求自動採檢方案。自動採檢方案的困難點至少包含有(1)二維影像欠缺深度資訊,影響自動採檢系統準確度與安全性、(2)口腔範圍狹小,難以使用市售3D成像裝置建立口腔三維影像、(3)採檢方法過於單一,難以適用於各種情況。 In addition, in order to effectively apply medical human resources, all walks of life are striving for automatic inspection solutions. The difficulties of the automatic inspection plan include at least (1) the lack of depth information in the 2D image, which affects the accuracy and safety of the automatic inspection system; (2) the narrow oral area makes it difficult to use commercially available 3D imaging devices to create three-dimensional oral images; (3) The collection and inspection method is too simple, and it is difficult to apply to various situations.
因此,有需要提供一種先進的生物檢體自動採檢系統及其採檢方法與應用,來解決習知技術所面臨的問題。 Therefore, there is a need to provide an advanced automatic collection and inspection system for biological specimens, a collection and inspection method and application thereof, to solve the problems faced by the prior art.
針對上述問題,本揭露係為因應現今受新冠肺炎影響下,為有效防堵疫情而進行的自動採檢需求。目前各界極力發展自動採檢方案,然而自動採檢多以二維影像結合力量回饋裝置,辨識受檢者口腔位置後用統一的機器手臂採檢移動路徑進行採樣,缺乏受檢者口腔空間資訊,在採檢上易有安全上之疑慮;且採檢手法過於單一,其正確率也令人存疑。本揭露是以視覺快速重建口腔三維點雲結合深度學習機器手臂採檢姿態之技術手段,達成機器手臂仿人手法快速採檢之功效。 In response to the above problems, this disclosure is in response to the need for automatic collection and inspection in order to effectively prevent the epidemic under the influence of the new crown pneumonia. At present, all walks of life are trying their best to develop automatic sampling and inspection solutions. However, automatic sampling and inspection mostly use two-dimensional images combined with force feedback devices to identify the position of the subject's mouth and then use a unified robotic arm for sampling and inspection. It is easy to have safety concerns in the collection and inspection; and the collection and inspection method is too simple, and its accuracy is also questionable. The present disclosure is based on the technical means of visual rapid reconstruction of oral 3D point cloud combined with deep learning of the robot arm's inspection posture to achieve the effect of rapid inspection by the robot arm's humanoid method.

接續,採用遞迴融合神經網路(recurrent neural network)127c比較不同三維網格特徵圖的特徵,將這些三維網格 特徵圖(n=1-f)融合形成三維網格特徵圖Gp。再以立體網格預測模組(3D grid reasoning)127d,使用立體捲積神經網路(3D convolutional neural networks)來計算相匹配成本積(matching cost volume),將三維網格特徵圖Gp的匹配成本積解碼成為一個具有體積/表面/視差(3D volume/surface/disparity maps)等立體空間資訊的三維網格特徵圖Go。 Continuing, the recursive neural network (recurrent neural network) 127c is used to compare the features of different three-dimensional grid feature maps, and these three-dimensional grid feature maps are combined. (n=1-f) is fused to form a three-dimensional mesh feature map Gp . Then, the 3D grid reasoning module (3D grid reasoning) 127d is used to calculate the matching cost volume using a 3D convolutional neural network, and the matching cost volume of the 3D grid feature map Gp is calculated. The cost product is decoded into a 3D mesh feature map G o with stereo spatial information such as volume/surface/disparity maps (3D volume/surface/disparity maps).
