This protocol uses multi-view stereo to generate three-dimensional (3D) models out of uncalibrated sequences of photographs, making it affordable and adjustable to a surgical setting. Strain maps between the 3D models are quantified with spline-based isogeometric kinematics, which facilitate representation of smooth surfaces over coarse meshes sharing the same parameterization.

Stereo-electroencephalography (SEEG) aids in localization of epileptogenic zones, however, remains relatively underutilized in the United States. The goal of this abstract is to provide a brief introduction to the technique of SEEG and further a detailed technique of using robotic assistance in the placement of SEEG electrodes.
FAQs
Binocular disparity provides a depth cue by comparing the positions of corresponding features in images captured from different viewpoints. The difference between those image positions supplies spatial information that a single view cannot provide. When researchers combine disparity with camera calibration, they can triangulate an object’s position and represent movement within a three-dimensional scene.
Synchronization ensures that the images being compared represent the same moment in the scene. This temporal alignment is essential when an animal moves, because mismatched frames could make corresponding features appear displaced for reasons unrelated to true depth or movement. Proper synchronization therefore supports more accurate three-dimensional reconstruction of posture, locomotion, and reaching.
Camera calibration establishes the imaging relationships needed to interpret measurements from the different camera views. After corresponding features are matched, calibrated views allow researchers to use triangulation to estimate an object’s position in three dimensions. Without this step, the recorded images would provide multiple perspectives but would not support the same precise spatial reconstruction.
A typical workflow begins by arranging two or more cameras to view the same experimental scene, then synchronizing their recordings and calibrating the camera setup. Researchers next identify corresponding features across the images, use binocular disparity and triangulation to reconstruct positions, and analyze the resulting three-dimensional movement. This converts recorded behavior into quantitative spatial data.
Stereo Camera Recording can support quantitative analysis of animal posture, locomotion, reaching, and interactions with experimental environments. The reconstructed three-dimensional coordinates allow investigators to examine how body position and movement unfold in space rather than relying only on two-dimensional video. This is especially useful when behavior includes complex movements or interactions that require spatial interpretation.
Researchers can align three-dimensional behavioral measurements with neural recordings to examine relationships between brain activity and movement. For example, reconstructed posture, locomotion, or reaching can provide quantitative behavioral variables for interpreting sensorimotor signals. This combined approach supports more precise studies of how neural activity relates to actions performed within an experimental environment.
