System and method for detecting platform inclination angle of digital slice pathology scanner

Abstract

The invention discloses a system and method for detecting a platform inclination angle of a digital slice pathology scanner. The method for detecting a platform inclination angle of a digital slice pathology scanner comprises following steps: S1 a light source is turned on; S2 a lens of a microscope unit is moved by a driving unit so that an image acquisition unit forms images for multiple focus regions to obtain image data; S3 according to the image data, vertical distance of each focus region relative to the image acquisition unit is obtained, and according to the vertical distances of all focus regions relative to the image acquisition unit, the inclination angle of a scanning platform is obtained; S4 whether the inclination angle equals to zero or not is determined, if the inclination angle does not equal to zero, the scanning platform level angle is regulated and step S2 is carried out; if the inclination angle equals to zero, then the test is finished. According to the method for detecting a platform inclination angle of a digital slice pathology scanner, through camera imaging for focus regions one by one to form image data, and based on the image data, the inclination angle of the scanning platform is obtained so that the position of the scanning platform is regulated and the scanning platform is kept in a horizontal condition, and the accuracy requirement of the scanner is satisfied.

Description

technical field [0001] The invention relates to the field of microscopic technology, in particular to a system and method for detecting the inclination angle of a platform of a digital slide pathological scanner. Background technique [0002] The digital slide pathological scanner is used to scan and collect traditional glass pathological slices through a fully automatic microscope or optical magnification system to obtain high-resolution digital images. Due to the high magnification, digital slide pathology scanners have particularly high requirements on precision. When the camera is scanning and collecting, the scanning plane needs to be parallel to the plane of the scanned target. If the scanning plane is not parallel to the plane of the scanned target, that is, there is an inclination angle between the scanning plane and the horizontal, then the final scanned image will have geometric deformation. . Since the scanning accuracy of the digital slide pathology scanner can...

When a level is used for detection, a bubble level is generally used for detection. The sensitivity of the level is divided into 0.01mm / m, 0.02mm / m, 0.04mm / m, 0.05mm / m, 0.1mm / m, 0.3mm / m and 0.4 mm / m, cannot meet the accuracy requirements of digital slide pathological scanners, and the higher the sensitivity, the higher the price of the level

When using an industrial laser rangefinder for distance measurement, the accuracy is generally around 1mm, which cannot meet the accuracy requirements of a digital slide pathology scanner, and the industrial laser rangefinder is expensive, which increases additional costs
