Embodiment Construction

[0025] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] figure 1 The schematic diagram of the minimum bounding box virtual measurement based on augmented reality is shown, which consists of a realistic measurement environment model, an augmented reality virtual measurement environment model and a human-computer interaction model. Among them, the realistic measurement environment model describes the visual perception configuration structure for obtaining the smallest bounding box of the measured object in the axial observation scene. Suppose the world coordinate system in the tested scene is O - X w Y w Z w , the minimum bounding box coordinate system of the measured object is O - XYZ , there exists only between the two coordinate systems X , Y Translation in the direction of the axis and around the Z axis rotation, the visual perception configuration structure corresponds to the imaging mode of the mini...
