Systems, methods, and apparatus for piggyback camera calibration
Systems, apparatus, and methods for piggyback camera calibration. Existing piggybacked capture techniques use a “beauty camera” and an “action camera” to capture raw footage. The user directly applies the EIS stabilization track of a piggybacked action camera to the cinematic footage to create desired stable footage. Unfortunately, since the action camera may have been slightly offset from the cinematic video camera, the EIS stabilization data will only roughly approximate the necessary corrections. In other words, the user must manually fine tune the corrections. The disclosed embodiments use a calibration sequence to estimate a physical offset between the beauty camera and the action camera. Then, the estimated physical offset can be used to calculate an offset camera orientation for stabilizing the beauty camera. The foregoing process can be performed in-the-field before actual capture. This allows the user to check their set-up and fix any issues before capturing the desired footage. |

Datasets can be represented in multi-sensory virtual reality environments according to some aspects described herein. For example, a computing system can receive a dataset of previously uncorrelated multivariate data points. Each multivariate data point can include multiple data attributes. The computing system can receive a command specifying associations between the multivariate data points and multi-sensory voxel characteristics. The computing system can generate a three-dimensional virtual reality environment that is comprised of voxels that have multi-sensory voxel characteristics based on the associations and values associated with the data attributes of the multivariate data points. The computing system can then output the three-dimensional virtual reality environment for rendering by a virtual reality subsystem. |
