Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description, but the utility model It is not limited to these embodiments.
Non-contact optical three-dimensional measuring apparatus of the present utility model as shown in Figure 1, 2, in the structure of " soil " font, native word Perpendicular pen is a slide rail 1, and one end (top for erecting pen) of slide rail 1 fixes a numerical control rotary head 2, can put and rotate Testee.The top bar of native word is first support 3, and support (the i.e. top bar) polycrystalline substance is engaged with slide rail, can So that along slide rail (erecting pen) upper and lower translation, to ensure that feed screw apparatus is steadily moved, slide rail sets two tracks.The frame upper is adopted Use the Slider platform on numerical control feed screw apparatus, leading screw to be moved left and right along leading screw, do what is set on one-dimensional accurate movement, leading screw Sliding block 4 can place testee as platform.The bottom bar of native word is second support 5, the support the same with top bar Polycrystalline substance is engaged with slide rail, can be along slide rail upper and lower translation.The midpoint (i.e. bottom bar midpoint) of second support 5 is fixed with Generating laser 7, the transmitter can be line laser or dot laser, and Laser emission direction is towards digital controlled rotary head, with slide rail (erecting pen) axis is vertical with two numerical control feed screw apparatus on same vertical plane.The two ends of second support 5 (i.e. bottom bar) An optical image sensor 6 is each provided with, two sensors are symmetrical arranged along second support midpoint, the optical axis of two sensors It is intersected on slide rail (erecting pen) axis vertical plane.Scale is carved with the side of slide rail (erecting pen), to confirm above and below two supports The distance of motion.Scale is also carved with two supports, to confirm the position of sliding block and optical image sensor.The measurement apparatus Rotary head, slide rail, first support, second support, traverse gear are each to realize using the control of high precision numerical control system The steady of individual structure is moved and is accurately positioned.
The application method of measurement apparatus of the present utility model is:
1st, world coordinate system is determined first.Using the center of rotation platform as coordinate origin, slide rail axis direction is used as Z To, numerical control feed screw apparatus direction as X to according to right-hand rule, determining Y-direction.
2nd, when needing some fixed characteristic points of one object of measurement, object is placed on rotary head, in object The heart is close proximity to the center of rotary head, and turntable do not take exercises, and opens generating laser, and laser (point or line) should be radiated at tested In the characteristic point of object, two optical sensors gather image (binocular measurement) simultaneously, can also only use an image sensors Gather image (monocular).During test, upper bracket is moved down, close proximity to second support, it is to avoid it blocks tested Object.According to binocular Measurement Algorithm or monocular algorithm, three coordinate positions of characteristic point are solved.
3rd, when needing the full surface of one object of measurement (testee generally has the characteristic of revolving body), it is tested Object is placed on rotary head centre position (center of the object center close proximity to rotary head), equally avoids upper bracket from hiding Keep off testee.Laser is radiated at body surface, controls head edge clockwise or counterclockwise, optical sensor continuous acquisition Subject image, rotary speed and picture-taken frequency can be with control selections.According to binocular Measurement Algorithm or monocular algorithm, ask Solve three coordinate positions of characteristic point.The angle rotated further according to every two field picture, solves the outer surface of whole testee Three-dimensional coordinate position.
4th, when needing some special surface of one object of measurement (object does not possess typical revolution bulk properties), The object is placed on the sliding block of upper bracket, control slide block is translated along support or so, laser the is inswept surface, image sensing Device continuous acquisition subject image, object translation speed and picture-taken frequency can be with control selections.According to binocular Measurement Algorithm or Monocular algorithm, solves three coordinate positions of characteristic point.Further according to every two field picture translational movement, whole testee is solved Outer surface three-dimensional coordinate position.
The three-dimensional measuring apparatus is not limited to said structure, for example, first support can also be using the belt laterally set Transmission device (or other appraise transmission through discussion), testee is placed on belt, realizes that testee body is left by belt transmission Move right, then pass through imaging sensor continuous acquisition subject image.
The traditional fixation measuring of three-dimensional measuring apparatus collection of the present utility model, rotation sweep measurement, translation scan measurement etc. Pattern is integrated, and can be met the demand of a variety of testees, be reduced operating procedure, save the testing time.The measurement apparatus It is easy to use, can according to the position of the Character adjustment testees such as contour structures, the size of testee and optical sensor, Optical sensor can be selected to gather the scan frequency of image, rotary speed, point-to-point speed etc. according to demand, selected always according to demand The type (laser line generator or dot laser) of generating laser is selected, the testing requirement of various testee bodies is flexibly met.Meanwhile, The device is applied to monocular or binocular measurement pattern, further increases measurement efficiency, reduces error and produces link, saves Cost.
