摘要： Embodiments of the present invention provide a Raman spectroscopic inspection method, comprising the steps of: measuring a Raman spectrum of an object to be inspected successively to collect a plurality of Raman spectroscopic signals; superposing the plurality of Raman spectroscopic signals to form a superposition signal; filtering out a florescence interfering signal from the superposition signal; and identifying the object to be inspected on basis of the superposition signal from which the florescence interfering signal has been filtered out. By means of the above method, a desired Raman spectroscopic signal may be acquired by removing the interference caused by a florescence signal from a Raman spectroscopic inspection signal of the object. It may inspect correctly the characteristics of the Raman spectrum of the object so as to identify the object effectively.

摘要： The present disclosure provides a method and a system for inspecting goods. The method includes the steps of: obtaining a transmission image and a HSCODE of inspected goods; processing the transmission image to obtain a region of interest; retrieving from a model library a model created based on the HSCODE, in accordance with the HSCODE of the inspected goods; and determining whether there are any goods not registered in a customs declaration that are contained in the region of interest based on the model. With the above solution, it is possible to inspect goods in a container efficiently, so as to find out whether there are goods not indicated in the customs declaration that are concealed in the container.

摘要： A method of evaluating an image quality for an imaging system and the imaging system are provided. The method in some examples includes: acquiring an image to be evaluated which is generated by the imaging system; extracting a number of sub-images from the image; obtaining a coefficient vector indicating a degree of sparsity by applying a sparse decomposition on the sub-images based on a pre-set redundant sparse representation dictionary; and performing a linear transformation on the coefficient vector so as to obtain an evaluation value for the image quality. The sparse dictionary is learned by only using a few high quality perspective images, and then the image quality is evaluated based on the sparse degree of the image obtained by using the sparse dictionary. A convenient and rapid no-reference image quality evaluation is achieved.

摘要： This invention relates to a movable divided inspection system and method, wherein the scanning inspection system comprises a first radiation source, a first detection means, a first automated guided vehicle and a second automated guided vehicle. The first radiation source is mounted on the first automated guided vehicle. The first detection means is mounted on the second automated guided vehicle. The first automated guided vehicle and the second automated guided vehicle are able to drive the first radiation source and the first detection means to a preset scan inspection position, so as to form a scanning passage for passage of an article to be scanned between the first and second automated guided vehicle, such that scanning inspection of said article to be scanned is realized by relative movement of said article to be scanned with reference to said first automated guided vehicle and said second automated guided vehicle.

摘要： The present disclosure provides a system and method for inspecting an aircraft. An X-ray/Gamma ray radiation source and a detector are located at above and below a fuselage of an aircraft, respectively. The X-ray/Gamma ray radiation source emits a beam of radiation[ ], wherein the X-ray/Gamma ray radiation[ ] passes through the aircraft to be inspected. The detector receives and converts the beam of X-ray/Gamma ray radiation[ ] that has passed through the aircraft to an output signal, and the system generates a vertical transmission image in real time.
