The invention discloses a biplane calibration method with calibration, which comprises the following steps: acquiring an image in a first direction, acquiring an image in a second direction, constructing a first rectangular coordinate system and a second rectangular coordinate system, and fitting the first rectangular coordinate system and the second rectangular coordinate system to obtain a third rectangular coordinate system. And further constructing a first angle coordinate system and a second angle coordinate system, then constructing a space coordinate system, and carrying out image space fitting on the image after the to-be-detected image is acquired based on the space coordinate system so as to realize posture recognition. According to the invention, the human body posture is recognized by using the double planes of the mobile phone, and the calibration assembly is combined with the optimization algorithm, so that the synchronous acquisition of the double cameras and the space acquisition of the optimi
