Abstract:
(EN) Provided are a focal-point testing method and apparatus (200) for substance detection, as well as a storage medium and a device (300) for use with the testing apparatus (200). The testing apparatus (200) comprises: a camera device and a laser emitter, wherein the focal point of the laser emitter is located on the focal plane of the camera device. The method comprises: acquiring, in order, Raman spectrum data, the area of a point of light, and image characteristics of a determination area for each moment of collection (101); and when, at a first moment of collection, the area of a point of light is not within a first threshold range, or when, at the first moment of collection, the image characteristics of a determination area are not within a second threshold range, outputting notification information (102). Focal-point shifts can be discovered in a timely manner when Raman testing is carried out.
(FR) L'invention concerne un procédé et un appareil de test (200) de foyer pour la détection d’une substance, ainsi qu'un support de stockage et un dispositif (300) destinés à être utilisés avec l'appareil de test (200). L'appareil de test (200) comprend : un dispositif de caméra et un émetteur laser, le foyer de l'émetteur laser étant situé sur le plan focal du dispositif de caméra. Le procédé consiste à : acquérir, dans l’ordre, des données de spectre Raman, la zone d'un point de lumière, ainsi que des caractéristiques d'image d'une zone de détermination pour chaque moment de collecte (101) ; et si, à un premier moment de collecte, la zone d'un point de lumière n'est pas située dans une première plage de seuil, ou si, au premier moment de collecte, les caractéristiques d'image d'une zone de détermination ne sont pas situées dans une seconde plage de seuil, fournir des informations de notification (102). Des décalages de foyer peuvent être identifiés de manière opportune lorsqu’un test Raman est réalisé.
(ZH) 一种用于物质检测的用于物质检测的焦点检测方法、装置(200)、存储介质及设备(300),应用于检测装置(200),该检测装置(200)包括:摄像装置和激光发射器,且激光发射器的焦点位于摄像装置的焦平面上,该方法包括:依次获取每个采集时刻的拉曼光谱数据、光点面积以及判定区域图像特征(101)。当第一采集时刻的光点面积不在第一阈值范围内,或第一采集时刻的判定区域图像特征不在第二阈值范围内时,输出提示信息(102)。能够在进行拉曼检测时及时地发现焦点偏移。
