Stereo, photogrammetric, plotting apparatus comprises a pair of projecting rods supported by universal joints. Each rod is associated with a plate-carrier carriage and is linked to the carriage by a joint in the form of a pin movable along a concave surface of the rod. Both rods are linked to a third carriage by a joint movable along the concave surfaces ot the two rods.

An arrangement for producing photographs which may be used for photogrammetric surveys of spatial objects, in which control points are established in the spatial object. Two photographs are taken using central projections with different positions of the projection center. The control points are the component of a mobile control point system having a reference with four points with known position coordinates constituting a quadrangle. At least two space points located outside the reference plane,...

Photogrammetric apparatus wherein a pair of stereophotographs have their images projected into the apparatus's optical system so as to form a stereomodel therein, which is visually observable through the optical system's binocular viewer. Relative movement of the optical system's measuring markers and the stereomodel is detected by moving a scanner device over the planar surface of a grid device, which serves as an encoder and develops command signals corresponding to the coordinates of a select...

Space simulator comprising two chambers carrying a stereoscopic photopair, two light sources carried by a stand and emitting two beams projecting on the two photographs of the photopair the images of the marks, and a stereoscoping viewing device for viewing the two beams. The marks are arranged so that they can be moved exclusively in a stationary plane P.sub.1 conjugated relatively to the lenses of the chambers with a plane P.sub.2 corresponding to the mean position of the photopair.

A method and apparatus is disclosed for determining the height, width, leh and orientation of an object from the feature image of the object found on oblique panoramic aerial photography. A magnifying eyepiece is provided with a calibrated reticle for measuring the dimensions of the feature image. The eyepiece also has a reference mark and indicia about the eyepiece for measuring the orientation from true north of the longitudinal axis of the feature image. The actual measurements of the object ...

A restitution instrument for measuring and evaluating picture plates. The instrument includes a mounting stage for mounting the plate. The stage has two edges forming a 90.degree. angle. A carriage means attached to the stage, is used for guiding the stage free of rotation in directions parallel to the edges, i.e., X and Y directions. A drive means is attached to the stage for driving the stage in the X and Y directions along the carriage means. The drive means includes a drive unit slidably mou...

A photogrammetric plotting apparatus is provided. The apparatus comprises an optical system means for viewing by an operator of an image of a first stereomodel derived from a pair of stereoscopically related photograms. The apparatus is further comprised of an operator controlled means for effecting stereomodel exploring motions relative to the photograms, and a tracing or display device. A means is provided for converting the exploring motions into plotting motions for the tracing or display de...

A photogrammetric method and apparatus for the stereoscopic examination and preparation of maps of featured surfaces in which a pair of stereo images is mounted on a carriage and a three dimensional measuring mark can be brought into conjunction with features on the three dimensional optical model produced from the stereo pair. Marking means are provided so that as the measuring mark means and the optical model are moved relatively to one another, drafting can be carried out on one or both of th...

A device for and a method of making a pair of stereo-maps from a series of sections obtained by sectioning an object at various levels. The device comprises support means having a first recording sheet fixed thereon, a second recording sheet placed over the first sheet and duplicating means interposed between the two sheets. A manually operable slider is mounted on the work bench to slide the second recording sheet in the direction X. An optical system is provided for projecting one of thtet ser...

An apparatus that allows the segregation of separated recyclable materials outdoors includes a wall unit mounted in an existing exterior wall of a domicile and between the existing studs therein. On the inner portion of the wall unit is a hinged, insulated cover and on the outer portion is a plurality of conduits extending outwardly and downwardly from the exterior wall of the home to allow for depositing of recyclable materials in appropriate bins or containers placed below.
