The invention discloses an optical distortion test method, apparatus and device, a storage medium and a system, and relates to the technical field of virtual reality. According to the method, the intelligent glasses are controlled to display the test image containing the plurality of test points, the test points displayed by the intelligent glasses are sequentially shot through the image acquisition equipment, and in the obtained local images, the test points are located in the central areas of the corresponding local images, namely in the central area (near the optical axis) of the view field of the image acquisition equipment; the distortion influence of the lens of the image acquisition device is minimum, and then the test point of the central area of each local image is utilized to carry out optical distortion test on the intelligent glasses, so that the optical distortion of the intelligent glasses can be effectively separated from the lens distortion of the image acquisition device, the influence of the lens distortion of the image acquisition device is reduced, and the detection accuracy of the intelligent glasses is improved. And the real distortion level of the intelligent glasses can be accurately evaluated.

The application discloses a cross-scene adaptive nutritional meal plan intelligent generation and execution management system, and relates to the technical field of computer information processing.The system builds a scene capability portrait of different application scenes, uniformly models and constraint-compiles nutritional targets, individual constraints and scene execution conditions, and generates executable nutritional meal plans matched with scenes such as hospitals, community medical institutions, enterprises and non-medical institutions.The application adopts a double-engine generation mechanism to improve the executability of the plans while meeting the nutritional constraints, and decomposes the generated plans into executable tasks for process management;through multi-source execution evidence collection and consistency evaluation, the application realizes objective evaluation of the plan execution, and automatically adjusts the plan when execution deviation or risk is triggered, forming a closed-loop adaptive management.The system can improve the adaptability, landability and management continuity of the nutritional meal plan in different scenes.

A method, system, storage medium, and program product for detecting non-methane total hydrocarbons (NMRs) are disclosed, relating to the field of testing or analyzing materials by measuring their chemical or physical properties. In this method, gas chromatographic data and component data are acquired, and the initial NMR concentration is calculated. CAS numbers are matched to distinguish known interfering components from dynamically added components. Preset response factors for known components and theoretical response factors for added components are obtained, and their accurate concentrations are calculated. The baseline NMR concentration deviation caused by interfering components calculated using the basic factors is calculated. This deviation is subtracted from the initial NMR concentration to compensate for the accurate concentrations of each interfering component, resulting in a corrected target NMR concentration. The target methane concentration is calculated and subtracted from the target NMR concentration to obtain the NMR concentration. This application aims to reduce the interference of dynamically changing added organic components on NMR detection, thereby improving the accuracy and intelligent processing efficiency of continuous NMR detection in complex waste gas scenarios.

The invention provides a field scene non-cooperative target measurement method, which comprises the following steps that: step 1, an unmanned aerial vehicle shoots multiple frames of field scene images through hovering, obtains high-precision self-positioning geographic coordinates of pixels corresponding to a cooperative target at corresponding moments in each frame of image, and establishes a control point set among the coordinates; step 2, fitting the control point set by using a quadric surface function, and obtaining a mapping relation of mutual mapping between coordinates of any pixel in the image based on fitting of each control point; and step 3, according to the pixel coordinates of the non-cooperative target in the aerial image, calculating to obtain the geographic coordinates of the non-cooperative target according to the mapping relation, and realizing the positioning measurement of the non-cooperative target in the field scene. According to the invention, the real-time position of the non-cooperative target such as the unmanned vehicle is used as the control point of the aerial image of the unmanned aerial vehicle in the field scene, and the positioning detection of the non-cooperative target on the flat ground in the image in the field scene is realized.
