Description

Automatic ground BRDF measuring stand
Technical field
The present invention relates to a kind of remote sensing science field and automation field of belonging to.
Background technology
The bidirectional reflectance effect is the intrinsic propesties of body surface and to the remotely-sensed data important influence.BRDF (bidirectional reflectance distribution function) has described the directive effect of object, is the function of wavelength, incident angle, reflection angle.The BRDF of ground survey target is significant to spectrum directivity characteristics, multi-angle remote sensing, the remote sensing radiation calibration of research object.
Ground survey BRDF comprises outdoor, indoor measurement.Outdoor measurement is incident light source with the sun, indoor measurement is incident light source with the artificial light source, measurement target is at the reflecting brightness of hemisphere direction all angles, require Measuring Time weak point, accurate positioning, measurement point shade abundant, that be subjected to measurement bay self to influence smaller particularly measurement bay can not drop in the measurement range, so that the BRDF characteristic of truer description target can't satisfy above-mentioned requirements and traditional measuring mechanism is simpler and cruder.
Summary of the invention
The purpose of this invention is to provide a kind of automatic ground BRDF measuring stand.
Automatic ground BRDF measuring stand, it is characterized in that comprising the azimuth circle track, zenith arc semi-circular track, be separately installed with synchronous cog belt on azimuth circle track and the zenith arc semi-circular track, on the azimuth circle track driving trolley is installed, the driving wheel of driving trolley and synchronous cog belt engagement, connect by pull bar between described driving trolley and the zenith arc semi-circular track, dragging zenith arc semi-circular track rotates on the azimuth circle track, on the zenith arc semi-circular track sensor dolly is installed, the engagement of driving wheel and zenith arc synchronous cog belt is installed on the sensor dolly; The rolling dolly is installed at the two ends of zenith arc semi-circular track and the rolling of azimuth circle track cooperates.
Described azimuth circle track is identical with zenith arc semi-circular track radius, and the center of circle of zenith arc semi-circular track is on the baseplane of azimuth circle track, and zenith arc semi-circular track and azimuth circle track offset are provided with.
Fixedly connected between two rolling dollies of described driving trolley and zenith arc semi-circular track lower end, the sensor dolly by active pull rod.
Described driving is by Synchronous Belt Drives.
The actuating unit of drive motor as driving wheel all is installed on described driving trolley and the sensor dolly.
Measurement bay mainly comprises azimuth circle track and zenith arc semi-circular track, adopts aluminum alloy materials and dyes blackly, and radius is 2 meters.Sensor trolley platform on the zenith arc semi-circular track can carry various spectrometers.On azimuth circle track, the zenith arc semi-circular track scale mark and indicating value are arranged, 1 ° of minimum scale.The azimuth circle track is assemblied to form by 4 equal portions circular arcs, and zenith arc semi-circular track is made up of 2 equal portions circular arcs, each circular arc physical dimension, similar weight, the dismounting of measurement bay, the transportation all more convenient.
Adjusting gear and universal wheel are equipped with in azimuth circle track bottom.The level of the adjustable measurement face of adjusting gear and height are adjusted altitude range 0~200mm.The integral body that the even universal wheel of installing is convenient for measuring on hardstand moves.The center of circle of zenith arc semi-circular track is on the azimuth circle baseplane, and the biasing of zenith arc is installed, and zenith arc shade is not dropped in the detector field of view scope, desirable 11 ° of detector maximum field of view angle.
Connect with pull bar between driving trolley and the zenith arc semi-circular track, constitute the space tetrahedron, the pull bar adjustable length is also lockable, to guarantee the intensity and the walking stability of zenith arc semi-circular track.
Drive system mainly is made up of servomotor, servo-driver, incremental encoder, servo brakes, synchronous cog belt, belt wheel.
Zenith arc semi-circular track can freely be rotated in 0 °~360 ° scopes on the azimuth circle track.The sensor dolly is along moving in zenith arc semi-circular track-75 °~+ 75 ° of scopes.
Drive motor bearing accuracy ± 3mm, default conditions (15 ° at interval of 30 ° of azimuthal separation, zenith angle are surveyed 66 location points altogether) are consuming time less than 10 minutes, measurement target is not influenced by the shade of zenith arc semi-circular track, can carry the BRDF that different detectors finishes on a surface target and measure.
The present invention has square for the driving of driving trolley and sensor dolly, and characteristic is good frequently, and response speed is fast, operates steadily the characteristics that bearing accuracy is high.
