Further, referring to fig. 2 and 3, the table top of the working table 1 is divided into a plurality of areas in advance, and during actual use, the working table can be divided into a plurality of areas with other numbers according to the image acquisition requirement.

Wherein the position information of the initial position (e.g. coordinates on the table top of the table 1) is preset and saved by the computer system 5. Since the current position of the target specimen 6 can be detected by the position sensor 40 of the electronic control system 4, it is determined that the system initialization is completed when the position sensor 40 feeds back the detected position information to the computer system 5 so that the computer system 5 recognizes that the current position information of the target specimen 6 is the initial position.
When image acquisition is carried out, the computer system 5 sends a corresponding position instruction to the electronic control system 4 by a target sample training program, the electronic control system 4 converts the instruction into the travel distance of the X/Y/Z motion mechanism, so that the target sample 6 moves to a specified position, the electronic control system 4 feeds back an execution result to the computer system 5, and the computer system 5 generates an image acquisition instruction again; the electronic control system 4 drives the image acquisition device 3 to execute an image acquisition task according to an image acquisition instruction sent by the computer system 5, and transmits acquired image data of the target sample to the computer system 5 after image acquisition at the position is completed. And repeating the above instruction sending process again until the image feature acquisition of all the positions required to be acquired is completed, thereby completing the feature data required by the target training. The computer system 5 may preset the position information of the target sample according to the feature data required to be acquired by the target training and the divided region of the table top of the workbench. In the present embodiment, the target sample training program run by the computer system 5 may be a training program in the prior art directly referred to, or may be a training program separately developed by a programmer according to training needs; the present application aims at the fact that the sample motion device 2 can drive the sample 6 to move to the target position within the range of the table top of the workbench 1 under the control of the electronic control system 4 and the computer system 5, and feed back the current position of the target sample 6 to the computer system 5, and as for how the computer system 5 converts the target sample training program into the target sample position information, the algorithm of the prior art or the algorithm developed separately can be adopted, which is not the technical problem to be solved by the present application, and is not repeated herein.
