In some examples, a system includes a range sensor configured to receive signals reflected from objects in an environment and generate two or more successive scans of the environment at different times. The system also includes a camera configured to capture two or more successive camera images of the environment, wherein each of the two or more successive camera images of the environment is captured by the camera at a different location within the environment. The system further includes processing circuitry configured to generate a three-dimensional map of the environment based on the two or more successive scans and the two or more successive camera images.
