Below just wherein preferred embodiment the present invention program is described in detail.
Referring to shown in Figure 1, be the schematic flow sheet of the stereo scene establishment loaming method embodiment of three-dimensional optimized wire selection system of the present invention, it comprises step:
Step S101: the three-dimensional coordinate according to rule mesh lattice point on the digital elevation model file is created relief block, enters step S102;
Step S102: the three-dimensional model of creating shaft tower according to the three-dimensional coordinate of the each point on the shaft tower in the shaft tower figure, calculate the coordinate of each point in the three-dimensional scenic of described relief block place of shaft tower according to the rotation angle of tower position, and each coordinate points of in the three-dimensional scenic of described relief block place, drawing shaft tower, enter step S103;
Step S103: according to artificial principle of stereoscopic vision, produce the physiology parallax by left and right sides stereogram, the space scenery stereoscopic vision in the reconstruction of three-dimensional scene is carried out three-dimensional range.
According to the scheme in the present embodiment, it is after simulating relief block according to digital elevation model, in the three-dimensional scenic at relief block place, realize model to shaft tower, and when carrying out the three-dimensional scenic roaming, be according to artificial principle of stereoscopic vision, produce sight equation by left and right sides stereogram, rebuild space scenery stereoscopic vision, thereby, when in this three-dimensional scenic, roaming, can hold integrated environment according to artificial principle of stereoscopic vision, can multi-angle, many depth of field ground free-roaming, support checking at any angle of three-dimensional scenic, for the optimization of electric power route selection provides support.
When creating relief block among the above-mentioned steps S101, be three-dimensional coordinate (x according to digital elevation model document convention grid points, y, z) create out the relief block that height rises and falls, can simulate terrain feature such as massif, the establishment mode of concrete relief block can be to adopt existing mode in the prior art, does not repeat them here.
When above-mentioned steps S102 simulates shaft tower, the implementation that one of them is concrete, it can be CAD figure in strict accordance with shaft tower, create the three-dimensional model of shaft tower according to the three-dimensional coordinate of each point on the shaft tower in the CAD figure, calculate the coordinate of each point in the three-dimensional scenic of relief block place of tower then according to the rotation angle of tower position, in this three-dimensional scenic, draw the each point of tower, thereby realize simulation tower.
Subsequently, can produce the physiology parallax by left and right sides stereogram, rebuild space scenery stereoscopic vision, realize true 3-D display, carry out three-dimensional range according to the principle of artificial stereoscopic vision.
The principle schematic of artificial stereoscopic vision has been shown among Fig. 2.When we during with eyes observation spaces far and near different scenery A, B, two produce the physiology parallaxes, obtain stereoscopic vision, thereby can judge the distance of scenery.If this moment, we respectively put a glass sheet before eyes, P as shown in Figure 2 and P ', then 2 of A, B obtain image a, b and a ', b ' respectively in glass sheet P and P '.If on glass have a photosensitive material, image will be recorded in respectively on P and the P ' sheet.After removing material object, watch the structure picture on the glass sheet separately respectively for two, still can see and the same space scenery A and B in kind the human-eye stereoscopic vision effect of Here it is space scenery produces physiology parallax on human eye nethike embrane nest.Its process is: space scenery is the structure picture on photosensitive material, produces the physiology parallax with the photo of eye-observation structure picture again, rebuilds space scenery stereoscopic vision.Such stereo perception is called artificial stereoscopic vision.
In the three-dimensional scenic that the present invention program creates, use artificial principle of stereoscopic vision, not only can support the circuit line walking, can also support free-roaming, promptly can realize the comprehensive demonstration of 360 degree of three-dimensional scenic by the position of adjusting 3 of picture points, camera point, human eye.Wherein, image point position is certain any ground three-dimensional coordinate (x, y, z) on the image, and camera point position is the three-dimensional coordinate (x, y, z) of camera focus, and position of human eye is the three-dimensional coordinate (x, y, z) of simulated person's eye.Below just to realizing that by the position of adjusting 3 of picture points, camera point, human eye the examples of the comprehensive demonstration of 360 degree of three-dimensional scenic describe:
In one of them example, can revise the horizontal parallax size of image, can realize the stereoeffect of three-dimensional scenic by regulating the relative position of left and right sides image with respect to human eye;
In another example, can keep the position coordinates of camera point, human eye in the three-dimensional scenic constant, control the visual range of human eye by the three-dimensional coordinate of revising picture point.When picture point was put away from camera, it is big that visual range becomes, and image dwindles, and can simulate human eye away from scene; Same visual range diminishes when picture point during near camera point, and the image amplification can be simulated the close scene of human eye, realizes the effect of image-zooming with this;
In another example, can be constant by the position coordinates that keeps picture point in the three-dimensional scenic, revise the three-dimensional coordinate of simulated person's eye and can realize rotating the effect of checking around a certain position;
