[0008] Figure 4 exist image 3 The object space scanning system in the single scanning working mode, the timing fragments of each component work, it can be seen that during the working process of the translation platform and the camera, the upper computer and the timing synchronization circuit are in an idle state of resources. In addition, the upper computer and the timing synchronization circuit All have certain parallel computing resources and can perform multi-threaded work. This serial working mode of a single system only uses one thread in the parallel resources, wasting a lot of thread resources
[0009] At present, there is no solution at home and abroad that can decouple system components, reduce system integration, and at the same time enable large-scale replication and cluster control of the system

The invention discloses a separate and distributed control method of an object-space scanning imaging system. The method includes: step 1, setting up a management layer, a monitoring layer, a control layer and a field layer; step 2, through the management layer, the user issues a scan imaging task, and transmit the scanning imaging task to the monitoring layer; Step 3, process and forward the scanning imaging task and analyze the scanning imaging task through the monitoring layer, generate scanning imaging instructions, and transmit the scanning imaging instructions to the control layer; Step 4, through The control layer receives scanning imaging instructions, and the motion control software and image acquisition software independently control the field layer equipment to complete the scanning work in a parallel manner based on the input scanning imaging instructions; Step 5, transmit the registration and splicing results back to the monitoring through the control layer layer database for storage. The present invention adopts a single host and multi-slave structure system to build an integrated control system for multiple independent object-dimensional scanning imaging systems, thereby realizing system-level control of large-scale object-dimensional scanning clusters.
Description
technical field [0001] The invention relates to an imaging control method, in particular to a separate and distributed control method for an object-space scanning imaging system. Background technique [0002] The object-space scanning imaging system is a kind of high-resolution / large-field scanning imaging system designed for microscopic or mesoscopic samples. Such as figure 1 As shown, in this type of scanning imaging system, the sample is fixed on the stage with electric translation function (hereinafter referred to as the translation stage), and the fixed image acquisition device (hereinafter referred to as the camera) moves perpendicular to the stage It is fixedly installed in a plane or obliquely to a certain movement plane, and the scanning is realized through the precise movement of the translation stage. In order to obtain a complete image with a large field of view, it is necessary to perform registration and stitching operations on the images collected by the cam...
