[0130] First embodiment of the present invention refers to:

[0131] The objective lens 101 moves a step to the current shooting height position along the objective mirror moving direction (Z-axis direction) 106, the carrier drives the target 203 to be efficiently moved from the first lateral position 301 to the second lateral position 302, line The camera captures a plurality of scanning line images during the vehicle movement according to the camera movement; then the objective lens 101 continues to move a step in moving the direction (Z-axis direction) 106 to the next shooting height position, the carrier drives the target The object 203 is moved from the second lateral position 302 to the first lateral position 301, the line array camera captures a plurality of scanning line images during the vehicle movement according to the photo trigger signal;

[0132] That is, the first embodiment refers to the traversal movement of the motor to generate a photographing trigger signal lin...

Abstract

The invention discloses a line array camera scanning method, which is used in a line array camera scanning system, comprising the steps of: acquiring an image of an object; selecting a plurality of marking points on the image of the object; Points are followed by high-precision focusing to determine the focus position of each marking point; according to the focus position of each marking point, the target is scanned with a line scan camera. It overcomes the selection basis of the best focal length based on the definition of a single scanning line in the prior art, which leads to the phenomenon that the image in the vicinity of the focal point is easy to appear unclear, and the shooting trigger signal of the line scan camera is controlled by the movement of the vehicle. Trigger generation, so that after the vehicle stops moving, a shooting trigger signal can be sent to avoid image distortion or misalignment caused by the line array camera taking pictures when the vehicle is moving, and improve the focusing accuracy of the line array camera, thereby improving the scanning accuracy .

Description

Technical field [0001] The present invention relates to the field of pathological slice scanning imaging, and in particular, to a wire array camera scanning method and apparatus. Background technique [0002] The line array scan camera is collected, and each time you collect a line, you just exercise until the next unit length, continue the collection of the next line, this time, a two-dimensional picture is taken for a while, which is similar to the color of the face camera. Picture to. During the operation of the wire array camera scanning system, due to the unevenness of the surface of the target object, the carrier of the target (subject / scanned) is also tilted, which can cause a focus of the overall focus of the target. Therefore, before the target object is scanned, it is generally necessary to select a plurality of tag points to be selected in the area to be scanned. [0003] In the prior art, the wire array camera scanning system has a low accuracy of multiple marker po...
