This system allows stereo plotting in CAD platform over aerial photographs with previously defined orientations. It’s specially useful for photogrammetric surveys made with drones, and it also can be used by public administrations, mining companies, landslide, hydrology, environment, town planning, etc.
Data Entry
Basic input data are the folder with the flight images and the external orientation file in several formats supported.
It’s possible to work with digital and analog pictures. For digital pictures the camera parameters and flight height are automatically obtained from metadata. Analogue pictures require to specify camera and flight data, such as focal distance, main point and average flight and terrain height.
Image Visualization
During project definition, images are converted to pyramidal format in order to optimize display performance. Imagas are organized in models, strips and block.
Models can be viewed in stereoscopic mode with low cost systems based on emitters and active glasses, or systems with two displays, mirror glass and polarized glasses. It also allows display with anaglyph glasses in pseudo-stereo mode (overlapped images) in any computer. You can also print and send these images by email.
The program can work with multiple stereoscopic models, switching automatically from one model to another by following cursor movements through terrain. It is also possible to know the real coordinates of the terrain and the height, measure 2D and 3D distances, slopes and elevation differences, perimeters and areas.
CAD drawing and editing
TcpStereo can syncronize with different CAD versions, so that a drawing can be loaded and show in stereoscopic mode selected layers, while keeping the center of frame and drawing automatically. Also you can draw points and polylines with constant or variable height in the same coordinate system.
If you also integrates with TcpMDT, the digital terrain model can be generated as well as creating contours, get profiles and cross sections, etc.
