The instructions are designed for Windows (64-bit) operating system with NVIDIA CUDA-enabled GPU. We recommend moving the camera in similar manners вЂ“ walking around in a circle while moving the camera up and down.

One way of video frame extraction is to use free open source software GIMP&GAP. would make it easier for the program to вЂunderstandвЂ™ and to locate the hood.ДЄlternatively, one can take videos of the scene/object, or shoot in burst mode (continuous high speed shooting).

A car hood itself is featureless (too smooth and uniformed) a zoom-out picture including side mirrors, windshield, ground, tires, etc. Always include surrounding features.ДЇor example, a piece of white wall is featureless a door frame would be feature on the white wall.

More features would help locate the camera.Try to take more images from different viewpoint to secure the reconstruction. Reflections and shadows do affect the programвЂ™s judgement.We recommend taking a new set of images for a separate reconstruction of the detailed feature, unless it has to be part of the general large-scale scene/object. This is to make sure the program could understand and relate the detailed feature to the whole scene. Do not move your camera dramatically in one single direction. If you want particular detailed features, take multiple pictures at equal intervals while slowly approaching the feature of interest. Ideally, frame your scene/object in the middle 1/3 to 2/3 of the picture. The scene/object should not look too large or too small. All cameras have a similar distance from the scene/object.All cameras are pointing to the scene/object (the Harley in this case).For a feature to be successfully reconstructed, it has to be seen by least three cameras.Try to keep two rays within 30 degree angle. Imagine the scene/object as the center of the circle the camera's viewpoint casts a ray to the scene, like the radius of the circle. Walk roughly in a circle surround the scene/object. Move to the next spot, take three images. Start at one spot, take three images at high, middle, low position.The surrounding pyramids shows the 3D position of the images taken. In the center is the motorcycle dense reconstruction result in VisualSFM. Thus, the general idea is to take images from slowly translating angles.Д«elow is an example of taking pictures of a motorcycle. Г view the scene from many angles to understand the three dimensional relationship. Note that distortion of the lens may affect the result modified photos may also cause inaccurate result. differences on resolutions, or image sizes, are acceptable). The images do not have to be taken with a single camera (i.e. Higher resolution images usually help preserve detail and get better reconstruction result. The idea is to get better quality images. We used Samsung Galaxy camera, which captures images that are 4608 pixels wide and 3456 pixels high and videos that are 1920x1080. Measurement and analysis: Use VisualSFM, Meshlab and CloudCompare tools to visualize and measure the deformation, as shown in the figure below (the bottom half).Дigital camera is recommended. Take advantage of these applications to get 3D models from images, as shown in the figure below (left to right process). Process the images for reconstruction: Install VisualSFM and CMPMVS. You will need to download and install a set of 3rd party software to analyze and visualize the data.Д¬apturing the images: Use digital camera to take images in sequence, in a pattern that sees the scene from all possible angles.
