Embodiment 1
[0026] see figure 1 and figure 2 , an automatic leveling method for bone marrow smear scanning, comprising the steps of:
[0027] (1) The robotic arm grabs the bone marrow smear 1 from the slide box, moves it under the laser rangefinder, and selects a square scanning area on the bone marrow smear 1 as the frame selection area 2 through the movement of the robotic arm. , the laser rangefinder is fixedly installed and kept still;
[0028] (2) The laser rangefinder first scans and measures the left boundary of the framed area 2 of bone marrow smear 1, and then scans and measures the right boundary of the framed area 2 of bone marrow smear 1 to obtain two sets of distance measurements data;
[0029] (3) The robotic arm adjusts the bone marrow smear 1 according to the distance measurement data difference between the left and right borders of the frame selection area 2 measured in step (2), and adjusts the left and right borders of the frame selection area 2 to the same height ...
Embodiment 2
[0033] Example 2, see figure 1 and image 3 , provides an autofocus method for bone marrow smear scanning, comprising the following steps:
[0034] (1) The robotic arm grabs the bone marrow smear 1 from the slide box, moves it under the laser rangefinder, selects a square scanning area on the bone marrow smear 1 as the frame selection area 2, and performs leveling on the bone marrow smear 1 operate;
[0035] (2) Under the 40x scanning lens, move the robotic arm, select a cell 3 in the frame selection area 2 for focusing operation, measure the distance of the cell under the clear cell image, take the cell image, and measure the distance of the cell. The distance value is used as the first focusing distance value;
[0036] In this embodiment, when focusing on the first cell selected in the frame selection area 2 under the 40X lens of the microscope, the mechanical arm grabs the bone marrow smear 1 and moves up and down along the Z axis, with the assistance of the laser rangef...
