Patent number: 11740075Abstract: A depth camera assembly (DCA) determines depth information. The DCA projects a dynamic structured light pattern into a local area and captures images including a portion of the dynamic structured light pattern. The DCA determines regions of interest in which it may be beneficial to increase or decrease an amount of texture added to the region of interest using the dynamic structured light pattern. For example, the DCA may identify the regions of interest based on contrast values calculated using a contrast algorithm, or based on the parameters received from a mapping server including a virtual model of the local area. The DCA may selectively increase or decrease an amount of texture added by the dynamic structured light pattern in portions of the local area. By selectively controlling portions of the dynamic structured light pattern, the DCA may decrease power consumption and/or increase the accuracy of depth sensing measurements.Type: GrantFiled: October 18, 2021Date of Patent: August 29, 2023Assignee: Meta Platforms Technologies, LLCInventors: Michael Hall, Xinqiao Liu, Zhaoming Zhu, Rajesh Lachhmandas Chhabria, Huixuan Tang, Shuochen Su, Zihe Gao
