Abstract: Motion and video data from vehicle sensors and camera arrays attached to a vehicle collect video and sensor data along a path driven by the vehicle. A system processes such data to produce high-accuracy structured map data, as might be used to precisely locate a moving vehicle in its environment. Positions are calculated from the sensor data. The positions are updated based on the video data. Positions of features in the video are used to create or update structured map data.

Abstract: Improved imaging devices and methods. A portable SPECT imaging device may co-register with imaging modalities such as ultrasound. Gamma camera panels including gamma camera sensors may be connected to a mechanical arm. A coded aperture mask may be placed in front of a gamma-ray photon sensor and used to construct a high-resolution three-dimensional map of radioisotope distributions inside a patient, which can be generated by scanning the patient from a reduced range of directions around the patient and with radiation sensors placed in close proximity to this patient. Increased imaging sensitivity and resolution is provided. The SPECT imaging device can be used to guide medical interventions, such as biopsies and ablation therapies, and can also be used to guide surgeries.

Abstract: Motion and video data from vehicle sensors and camera arrays attached to a vehicle collect video and sensor data along a path driven by the vehicle. A system processes such data to produce high-accuracy structured map data, as might be used to precisely locate a moving vehicle in its environment. Positions are calculated from the sensor data. The positions are updated based on the video data. When loops in the vehicle path are detected, a loop closure error is calculated and used to update the positions as well as to reduce bias in the sensors when calculating future positions. Positions of features in the video are used to create or update structured map data.
