[0048] Specifically, the observation plane has a certain visualization area, which is limited. Its horizontal range is the horizontal distance from the first electromagnetic sensor to the last electromagnetic sensor, and its vertical range is the vertical distance from the lowest electromagnetic sensor to the highest electromagnetic sensor.

[0049] Specifically, to ensure that all N electromagnetic sensors are on the same plane, this can be achieved by placing the electromagnetic sensors on non-metallic components, and ensuring that the non-metallic components are all aligned in a straight line. These non-metallic components can be non-metallic supports, non-metallic hooks, etc.

[0078]

[0079] The first projection matrix described in this embodiment refers to the projection matrix of the positioning information of the N electromagnetic sensors on the observation plane and the image coordinates, which can be obtained by solving the value of each element in the preset projection matrix using the least squares method.

[0080] Specifically, the least squares method for solving the problem is as follows:

[0081] [m 11 m 21 m 31 m 12 m 22 m 32 m 13 m23 m 33 ] T =(A T A) -1 A T b

[0082] Specifically, the first projection matrix obtained by solving is:

[0083]

[0084]

[0085] In this embodiment of the application, by calculating the first projection matrix, the correspondence between the positioning information of the N electromagnetic sensors when projected onto the first image is obtained. This is beneficial for determining the positional relationship of the N electromagnetic sensors on the first image and for realizing the visualization of electromagnetic field strength data.

[0086] Optionally, the image acquisition module is specifically used for:

[0098] The image acquisition module described in this embodiment is positioned between two lenses, meaning that the image acquisition module can be positioned in the middle part of the gap between the two lenses. Theoretically, it can be assumed that the image acquired by the image acquisition module is consistent with the image seen by the wearer's naked eye.
