The invention discloses a DSP (diarrhetic
shellfish poison) detection and
analysis method based on a
cell image sensor. The method is characterized by comprising the following steps: establishing the
cell image sensor which is high in performance and low in cost, acquiring an image, converting an acquired RGB (red green blue) image to a
grayscale image, binaryzating the image, matriculating the image, detecting a
peak value, detecting the variation of a pulse image of a
myocardial cell when in mechanical pulse, and detecting the mechanical
pulse rate, pulse range and pulse interval of the
myocardial cell; establishing a standard graph by detecting the response of the
cell image sensor to different standard sample working solutions of the
shellfish diarrhetic poisons in different concentrations; and detecting the response of the cell image sensor to the
shellfish diarrhetic poisons of unknown concentration, comparing the detected response result with the standard graph, and semi-quantitatively calculating the concentration of the poisons. Compared with the existing shellfish diarrhetic poison detection and
analysis method, the method is low in cost, simple in operation and capable of directly evaluating the
toxicity of the poisons for a long time.
