The invention discloses an object developing and calibrating method in a surgical environment. The method mainly includes the steps of: using at least one infrared LED (IR-LED) and at least one infrared sensor (IR-Sensor) on a surgical eyeglass, to have a surgical environment image； and retaining image signals within a first wavelength range and removing image signals not in the first wavelength range in the surgical environment image. The method helps the surgeon see only the object images on the surgical eyeglass without the interference of non-surgical environmental imaging noises.
