Aiming at the measurement of test point electrode coordinates in biomedical signals, a new method of "contactless image processing" is proposed by taking brain wave testing as an example: the test image is obtained by a digital camera, and then the test point electrode information is extracted and separated by computer image, and then the data query comparison and linear fitting approximation are used to realize three-dimensional reconstruction. The experimental results show that 80% of the test points can meet the accuracy requirements, which is a useful attempt to realize the intelligence of "soft instead of hard" sensing.
