Patent number: 10705193Abstract: Methods, systems, and devices are provided for calibrating a light ranging system and using the system to track environmental objects. In embodiments, the approach involves installing light ranging devices, such as lidar devices, on the vehicle exterior. The light ranging system may be calibrated using a calibration device to scan the vehicle exterior and construct a three-dimensional model of the vehicle exterior comprising the positions of the installed light ranging devices on the vehicle exterior. The calibrated light ranging system may use the model in conjunction with ranging data collected by the installed light ranging devices to track objects in the environment. In this way, the light ranging system may detect a proximity of environmental objects and help a driver of the vehicle avoid potential collisions. The light ranging system may further measure the vehicle exterior and thereby detect changes to the vehicle exterior.Type: GrantFiled: December 7, 2018Date of Patent: July 7, 2020Assignee: Ouster, Inc.Inventors: Angus Pacala, Dmitri Garbuzov, Daniel Lu, Wil Selby, Mushfiqur Rouf, Henru Wang, Kairen Wong

Patent number: 8861851Abstract: Methods and apparatus may be applied to reconstruct pixel values in saturated regions of an image. Saturated regions are identified and hues for pixels in the saturated regions are estimated based on hues in boundaries of the saturated regions. Gradients for pixel values in saturated color channels within the saturated region may be estimated based on known gradients for non-saturated color channels. Reconstructed pixel values may be derived from the estimated gradients. The methods and apparatus may be applied in conjunction with dynamic range expansion.Type: GrantFiled: May 3, 2012Date of Patent: October 14, 2014Assignee: Dolby Laboratories Licensing CorporationInventors: Wolfgang Heidrich, Mushfiqur Rouf
