XY direction included angle measurement and motion compensation method based on image microscopic scanning platform

Abstract

The invention discloses an X-Y direction included angle measurement and motion compensation method based on an image microscopic scanning platform, which can help instrument assembly personnel to conveniently and intuitively judge and measure the installation included angle of the scanning platform in the motion direction, and readjust the structure assembly of the platform according to the measured included angle. When the scanning platform moves in the X-axis direction and the Y-axis direction, the moving direction is kept vertical or corresponding motion compensation is carried out on the platform along a scanning track motion acquisition image according to the included angle of the moving direction; the problem that the scanning platform cannot accurately complete efficient splicing of collected view images due to the fact that the installation perpendicularity in the two movement directions does not reach the standard is solved, the image processing efficiency in the automatic scanning process is effectively improved, and the process implementation difficulty of later image splicing is lowered. And the working difficulty and intensity of technical assembly personnel are reduced, the debugging efficiency and precision are ensured, the method has important significance in maintaining stable image acquisition of an automatic microscopic scanner, and the method has a wide application prospect in the medical pathological slide microscopic vision automatic detection industry.

Description

technical field [0001] The invention relates to the technical fields of medical information collection and detection and clinical medicine, in particular to a method for angle measurement and motion compensation based on an image microscopic scanning platform in XY directions. Background technique [0002] With the continuous increase of inspection level and inspection demand, the automatic microscopic scanning platform shows more convenient, accurate and efficient characteristics than traditional microscopes, and has been widely used in various fields, while traditional manual microscopy requires pathologists or experts. The operation by professionally trained physicians is no longer suitable for the situation that the number of samples to be examined is large and the time for obtaining microscopic examination results is short, and the long-term manual microscopic examination operation may easily lead to visual fatigue and other conditions that affect the microscopic examina...

Problems solved by technology

[0005] In this way, the existing measurement methods are difficult to ensure that the scanning platform can meet the verticality requirements in the X and Y directions during the movement process

Therefore, in the actual scanning process, due to problems such as installation accuracy, the collected field of view images often have problems such as image content inconsistency and too large image area during the mosaic process, resulting in the failure of the mosaic image or the difficulty of satisfying the follow-up image requirements. required for work
