A system and method for performing robust depth calculations with time of flight (ToF) sensors using multiple exposure times is disclosed. A three-dimensional (3D) depth sensor assembly captures a first array of n point values, where each point value of the first array has a respective first-array depth component and a respective first-array quality component. The 3D depth sensor assembly then captures a second array of n point values, where each point value of the second array has a respective second-array depth component and a respective second-array quality component. A processor then renders a 3D point cloud comprising a third array of n point values, where each point value of the third array has a respective third-array depth component. The respective third-array depth component for each point value of the third array is based on either the corresponding respective first-array depth component or the corresponding respective second-array depth component.

Techniques for coloring a point cloud based on colors derived from LIDAR (light detection and ranging) intensity data are disclosed. In some embodiments, the coloring of the point cloud may employ an activation function that controls the colors assigned to different intensity values. Further, the activation function may be parameterized based on statistics computed for a distribution of intensities associated with a 3D scene and a user-selected sensitivity. Alternatively, a Fourier transform of the distribution of intensities or a clustering of the intensities may be used to estimate individual distributions associated with different materials, based on which the point cloud coloring may be determined from intensity data.
