Image processing software
The storage/printing function: it can store all images and data obtained by the video spectral comparator during the inspection process, and can be used in conjunction with a printer to print out the required images.
The comparison function: it can perform horizontal and vertical stitching or overlapping comparison between two detected images. Static and dynamic images can be compared in real-time.
Gray value measurement: it can measure the gray value of any specified point or area in the image. And the grayscale changes at that location under various detection conditions can be displayed in the form of curves. This method is particularly advantageous for identifying subtle grayscale differences between different texts in the image formed by the inspected document that are difficult for the human eye to detect.
Depth of field automatic synthesis
Processing Blurred image
Motion blur processing, geometric correction of deformed images and fast image processing
Other image processing: It can do reflectivity and absorbance measurement, image measurement and annotation, extraction of the main part of the stamps, curve and linear image shaping, universal cutting comparison, image ghosting and other various image processing methods.
Main function
Multiple excitation light and receiving filter combinations are used to test the fluorescence differences of different inks.
The combination of reflective light source and receiving filter is used to test the absorption and reflection differences to different wavelength bands of light of different inks.
The combination of reflective light source and receiving filter is used to test the penetration effect to different infrared light bands of different inks.
The combination of transmitted light source and receiving filter is used to test the penetration effect to different infrared light bands of different inks.
The side light source illuminates the document in a grazing incidence manner to inspect the scratch and cutting marks on the document.
The transmitted light source illuminates the document from below upwards to inspect the traces of cutting and patching on the document.
Application
VSC-300 is mainly used for identifying alterations, covering up, adding, repairing, fading, forgery of documents, and encrypting documents, seals and receipts, fluorescence inspection, handwriting indentation, forging marks, fingerprint traces, trace evidence, ink detection, seal comparison, image measurement, image processing, etc. It is an ideal choice for Public Security Bureaus, procuratorates, courts and their colleges. It also can be applied to electronic, biochemical, agriculture, archaeology, banking, Customs and industries or sectors who have the requirements to detect or identify objects.
