Embodiment Construction
[0058] Such as figure 2 As shown, the present invention includes designing a multi-activity control system; digital camera calibration and photo orientation element calculation based on the multi-activity control system; and three-dimensional measurement based on the multi-activity control system. Specific steps are as follows:
[0059] Step 1: Design the activity control system; the steps are as follows:
[0060] Step 11: Design as figure 1 The activity control system adopts stainless steel tube structure. It is 1.2 meters high, the top and bottom are semicircles with radii of 0.15 meters and 0.3 meters respectively, and three semicircles are added in the middle. Set 5 "+"-shaped measurement marks on each semicircle, a total of 25 "+"-shaped measurement marks.
[0061] Step 12: Precisely measure the three-dimensional coordinates (X, Y, Z) of 25 "+"-shaped measurement marks on the activity control system by means of geometric measurement, and each activity control system ...
