Fig. 1 is the utility model structural representation.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
In Fig. 1, form the utility model by pointolite, parallel light tube, plane mirror, semi-permeable and semi-reflecting mirror, video processor, video camera, wherein first pointolite 1, parallel light tube 2 and second pointolite 3 are fixed on radar or the transit pedestal, are be rigidly connected (promptly being connected) between the three; First plane mirror 4, first semi-permeable and semi-reflecting mirror 5, second semi-permeable and semi-reflecting mirror 6, second plane mirror 7, first video camera 8, the 3rd semi-permeable and semi-reflecting mirror 10, video processor 12 and second video camera 13 are fixed on the inertial navigation pedestal, aim at two pointolites and parallel light tube respectively, also be between them and be rigidly connected; Described first plane mirror 4 is 45 degree with horizontal direction and is provided with, and on the light path of first pointolite 1, first semi-permeable and semi-reflecting mirror 5 and first plane mirror 4 be arranged in parallel, on the light path of parallel light tube 2; Second plane mirror 7 is 135 degree with horizontal direction and is provided with, on the light path of second pointolite 3; Second semi-permeable and semi-reflecting mirror 6 and second plane mirror 7 be arranged in parallel, and with first semi-permeable and semi-reflecting mirror 5 on same horizontal line; The 3rd semi-permeable and semi-reflecting mirror 10 is parallel to second semi-permeable and semi-reflecting mirror 6 and is provided with; First video camera 8 is installed on the refractive light paths of the 3rd semi-permeable and semi-reflecting mirror 10, second video camera 13 is installed on its direct projection light path, first video camera 8 and second video camera 13 all adopt ccd video camera, dispose first optical lens 9 and second optical lens 11 respectively, video processor 12 is installed in the position near first video camera 8 and second video camera 13, and present embodiment is a setting video processor 12 between first video camera 8 and second video camera 13; First semi-permeable and semi-reflecting mirror 5, second semi-permeable and semi-reflecting mirror 6 and the 3rd semi-permeable and semi-reflecting mirror 10 are installed on the plane; The first～two pointolite 1～2 is with respect to the equivalent optical path of second video camera 13.
Wherein first video camera 8 and second video camera 13 all adopt the ccd video camera that has electronic shutter, are used to reduce dynamic measurement error.
The utility model principle is:
The light that sends from first pointolite 1 shines on second video camera 11 through second semi-permeable and semi-reflecting mirror 6 and second optical lens 11 after first catoptron 4 and 5 reflections of first semi-permeable and semi-reflecting mirror again, and the light that sends from pointolite 3 also shines on second video camera 11 through second optical lens 11 after second catoptron 7 and 6 reflections of second semi-permeable and semi-reflecting mirror again.Because the relative position of two pointolites is fixed, their imagings on second video camera, 11 target surfaces can be used as multiple goal and separate; The light that sends from parallel light tube 2 shines on first video camera 8 after passing first semi-permeable and semi-reflecting mirror, 5,2 second semi-permeable and semi-reflecting mirror 6 and 10 reflections of the 3rd semi-permeable and semi-reflecting mirror.Certainly, the light that sends from parallel light tube 2 also can shine on second video camera 13, the light that sends from two pointolites also can shine on first video camera 8, but because both are respectively infinite distance and limited target far away, the focal plane of two video cameras does not overlap yet, therefore, the light that parallel light tube 2 sends is on second video camera 13 and first pointolite 1, the light that second pointolite 2 sends all is out of focus on first video camera 13, can not imaging, can be used as bright background process, in addition, require the equivalent optical path of two pointolites with respect to second video camera 13, both pictures could become on same focal plane like this.
When hull deformed, the locus and the direction of pointolite and parallel light tube also changed thereupon, and two video cameras can be measured these variations, through calculating, can obtain the three-dimensional perspective variable quantity.
