Correction and capture method for biological particle capture device

A correction and capture method for a biological particle capture device, comprising:

• providing an image observation unit, which faces a side of a carrier platform, on an observation platform and orientating a view region of the image observation unit towards a carrier region of the carrier platform for taking images;
• performing a fixed point displacement on the observation platform by the image observation unit based on a plurality of observation basic coordinates set on an observation platform coordinate system and defining a correction point in an image of the view region when the image observation unit is positioned at one of the plurality of observation basic coordinates and takes the image;
• controlling, by a terminal device, a particle capture tool on a capture platform to move relative to the carrier region on another side of the carrier platform based on a relative position of the image observation unit positioned at one of the plurality of observation basic coordinates, wherein a capture portion of the particle capture tool enters the image of the view region;
• adjusting the capture portion of the particle capture tool to align with the correction point and recording, by the terminal device, a capture correction coordinate of the capture portion located in a capture platform coordinate system of the capture platform;
• placing a carrier in the carrier region, and taking, by the terminal device, the plurality of observation basic coordinates previously recorded in the observation platform coordinate system in correspondence with a periphery of a particle and calculating, by the terminal device, a position of the image observation unit located at the correction point recorded in each of the plurality of observation basic coordinates when the image observation unit discovers the particle on the carrier, so that the terminal device acquires a plurality of correction basic coordinates around the particle on the carrier;
• simulating, by the terminal device, a virtual correction region in the view region of the image observation unit based on the plurality of correction basic coordinates, wherein a position of the particle correspondingly falls into the virtual correction region;
• simulating a first extension axis and a second extension axis based on the position of the particle by the terminal device, wherein the first extension axis and a first absolute X coordinate axis in the virtual correction region perpendicularly intersect to acquire a first joint X coordinate;
• the first extension axis and a second absolute X coordinate axis in the virtual correction region perpendicularly intersect to acquire a second joint X coordinate;
• the second extension axis and a first absolute Y coordinate axis in the virtual correction region perpendicularly intersect to acquire a first joint Y coordinate;
• the second extension axis and a second absolute Y coordinate axis in the virtual correction region perpendicularly intersect to acquire a second joint Y coordinate;
• and
• controlling the particle capture tool to correspondingly move to the position of the particle, wherein the terminal device takes the first joint X coordinate, the second joint X coordinate, the first joint Y coordinate, and the second joint Y coordinate, and uses a specific conditional formula to calculate and obtain a relative capture coordinate that the particle capture tool is required to correspondingly move.
