Abstract
A method for operating a 3D sensor system includes by an array of pixels of an imaging sensor of the 3D sensor system, generating first image data representative of reflected light from an environment, the image data having a first resolution. The method includes by processing circuitry of the 3D sensor system, generating second image data based on the first image data, the second image data having a second resolution less than the first resolution; and by the processing circuitry of the imaging sensor, determining that the second image data indicates that an object is present in the environment. The method includes responsive to the determining, providing the first image data from the 3D sensor system to one or more processors configured to generate a three-dimensional image of the environment based on the first image data.
