Commonly abbreviated three-dimensional or 3D or so-called space, is the shape of the object that has length, width, and height.This term is commonly used in art, animation, computers and mathematics. Remote sensing system of stereoscopic aerial photographs utilizing this technique to obtain information derived from air photo data series such as elevation, distance, volume and others. To produce a stereoscopic view of this, used observation tools that can generate stereoscopic views on the aerial photo that is stereoskop bertampalan. Through this stereoskop, objects contained in the patch area of the photo will look like three-dimensional images that can be measured height or depth of the object.
Three-dimensional view of the results of stereoscopic observations appear in the brain as a result of a combination of two images with different viewpoints. Each eye of the observer (observer) will get the information from the images that are below it. Information from both images are received by the human brain and interpreted as a three-dimensional image. A series of aerial photographs would appear to be three-dimensional view of the stereoscopic observation if: ü aerial photograph has a patch ü Pictures of aerial photographs have a different angle in a similar flight path ü The photo should have observed the same scale Apart from the requirement of the aerial photograph mentioned above, the ability of any person to produce three-dimensional effects are also very varied. Not every observer has the same ability to produce a three dimensional picture of the same series of aerial photographs. Couple of factors such as distance pupils, much closer focus capability of view, and others are very influential on a person's ability to generate three-dimensional picture. Age of a observer also allows changes in the ability of observers to generate three-dimensional view. Thus an expert fotogrametris working with stereoscopic images also have the possibility of having difficulty forming a three dimensional picture in a particular period. Ø Angle Paralactic Parallax, or more accurately motion parallax is the change in position angle of the two stationary points, relative to each other, as was observed by an observer moving. Simply put, parallax is a visible shift from an object (point 1) of the background (point 2) caused by changes in the position of the observer. Parallax is often defined as "movement that looks" of an object against a distant background due to a shift in perspective as can be seen in Figure 1. When viewed from the point of view A, the object appears in front of a blue box. When the point of view is changed to the point of view B, the object appears to move forward the red box. This phenomenon is commonly used in astronomy to determine the distance of celestial objects. The method of determining distances sky objects is essentially a special case of triangulation, in which we can determine the length of two sides of a triangle, if one of the sides and corners are known. For the case of distance determination by the method of parallax, the triangle formed by the two-point position of the observer and the object the sky is a very sharp triangle. The position of the two observation points are the base of the triangle and is usually determined by using measures such as the diameter of Earth and Earth's radius of the Earth's orbit around the Sun.Angle triangle can be determined by measuring the angle "a shift that appears" on the celestial sphere of the two observation points earlier. Discussion Observation of the two aerial photographs bertampalan done in order to get an impression on the depth and height of an area that is displayed in aerial photographs that bertampalan. Bertampalan means two pictures together showing some of the area or the same object. Stereoskop used in this lab is a kind of mirror stereoskop.Stereoskop mirror system can apply the fusion of two images. The fusion events could also take place at the shadows on the most acceptable of the left eye so it will show a picture of a conclusion of the memilikki oibjek an intact hemisphere and complex composition. Two aerial photographs bertampalan will be arranged in such a way so as to separate the two points would seem to be one, then the image is visually observed by rocks stereoskop would then look three-dimensional images in areas with air photographed will be seen very clearly the areas the ramps. From the aerial photos will be made topographic maps using an OHP transparent paper and markers so we can make the contour lines are transparent with a paper should pay attention to differences in the height of the landscape.
