Pressure measuring and analytic device based on image information processing technology

Abstract

A pressure measurement and analysis device based on image information processing technology mainly includes a pressure-image transmission unit, an image-data conversion unit, and a data processing and result reporting unit. The pressure-image transmission unit is composed of several pressure-bearing sacs distributed on the measured surface, corresponding conduits, and liquid-column tubes filled with colored liquid columns. The pressure-bearing bladder converts the change of pressure into the displacement of the liquid column in the liquid column tube, and then converts the displacement of the liquid column into an image through the liquid column tube array, and collects digital image data through a camera device and a video capture card and transmits it to the data processing and processing. The result reporting unit, the data processing and result reporting unit obtains the result according to the digital image data using the image information processing technology, and then outputs the result by the display or / and the printer. The invention has a simple structure and is especially suitable for accurate measurement when there are many pressure test points and efficient processing and reporting of large sample data.

Description

technical field [0001] The present invention relates to a pressure measurement and analysis device, specifically a pressure measurement and analysis device based on image information processing technology, especially suitable for the measurement and evaluation of soft objects such as mattresses, sofas, sports mats and the like . Background technique [0002] Measuring the force of soft objects such as mattresses, sports mats and the like requires not only measuring the force of individual points, but also evaluating the whole. Since the measurement accuracy is positively correlated with the number of measurement elements in the overall evaluation, in order to achieve sufficient accuracy, sometimes thousands of measurement elements are required. At this time, if the point-by-point measurement method is used, it is not only time-consuming and labor-intensive, but also the workload of data processing in the later stage is huge. There is a human body pressure testing system wi...
