In this article, a level ruler Precision Verification System program of the mobile-camera image processing technology that is based on the camera mobile image processing technology is proposed, as a result of the research for the existing barcode type level ruler verification system and a high-precision grating sensor system hardware structure is also built. Secondly, we calculate the uncertainty of the system, and at last do the system stability test that the results show that the system achieves the test requirements. On the barcode type level existing ruler verification system research, proposed a camera mobile image processing technology based on the level ruler of precision calibration system, builds a detection sensor system with high precision grating, realizes automatic acquisition level ruler barcode image, method of application without barcode image with barcode image subtraction the preliminary processing of image acquisition, eliminate the influence of background light on the image acquisition, the uncertainty of the calibration system of the theoretical calculation and experimental verification, the results show that the system achieves the test requirements.

Differential hysteresis processing is a new image processing technology that provides a tool for the display of image data information at any level of differential contrast resolution. This includes the maximum contrast resolution of the acquisition system which may be 1,000-times higher than that of the visual system (16 bit versus 6 bit). All microscopes acquire high precision contrasts at a level of <0.01-25% of the acquisition range in 16-bit - 8-bit data, but these contrasts are mostly invisible or only partially visible even in conventionally enhanced images. The processing principle of the differential hysteresis tool is based on hysteresis properties of intensity variations within an image.Differential hysteresis image processing moves a cursor of selected intensity range (hysteresis range) along lines through the image data reading each successive pixel intensity. The midpoint of the cursor provides the output data. If the intensity value of the following pixel falls outside of the actual cursor endpoint values, then the cursor follows the data either with its top or with its bottom, but if the pixels' intensity value falls within the cursor range, then the cursor maintains its intensity value.
