The cable channel device placement scene information may be scene information of a background rendering scene for the cable channel device model. That is, the background to which the device image in the sequence of subsequently acquired device images corresponds is a certain scene content in the rendered scene. The scene information may be a unique identification of the scene. The image acquisition device may be a device that acquires images. For example, the image acquisition device may be a camera. The device parameter information may be parameter information set in advance for the image capturing device. The device parameter information may be camera parameter information. For example, the device parameter information may include: a Field of view (FOV), a near parameter (a parameter for rendering at a position far from the camera), a far parameter (a parameter for rendering at a position cut-off at a position far from the camera), and a bottom parameter (an upper boundary parameter of a rendering space). The cable channel device model may be a three-dimensional model of the cable channel device.
And 102, placing a cable channel equipment model to be obtained by the image in a target position in a scene space corresponding to the cable channel equipment arrangement scene information.

The scene space may be a scene space corresponding to the rendering cable channel device arrangement scene information. The target location may be a target spatial point corresponding spatial point location of the scene space. For example, the target location may be the location of the origin in the scene space. The origin in the rendered scene space may be preset.
And step 103, determining the model mark position and model size information corresponding to the external surrounding equipment model.

Wherein the outer surrounding equipment model is a space model surrounding the cable passage equipment model, and the model position is at the target position. The outer envelope device model may be an outer envelope model of various shapes. The model marking location may be a location in the outsourcing device model that has marking utility. For example, the model mark position may be the model center point position, or may be the model center point position. The model size information may be information characterizing the model size. For example, the model size information may be model space information. The model of the outward surrounding equipment is a spherical three-dimensional model, and the model size information can be the sphere radius size.
