“…The three subpackages combined provide a processing pipeline from an initial 3-D model to a reconstructed 3-D model via rendered and compressed images. SISPO is a Python software package that is hosted on a public GitHub repository under a GPL v3.0 licence and is maintained by the authors [33] among other contributors (e.g., authors of this paper). A description of the core functionality and the additional models is provided in Fig 2.…”

This paper describes the architecture and demonstrates the capabilities of a newly developed, physically-based imaging simulator environment called SISPO, developed for small solar system body fly-by and terrestrial planet surface mission simulations. The image simulator utilises the open-source 3-D visualisation system Blender and its Cycles rendering engine, which supports physically based rendering capabilities and procedural micropolygon displacement texture generation. The simulator concentrates on realistic surface rendering and has supplementary models to produce realistic dust- and gas-environment optical models for comets and active asteroids. The framework also includes tools to simulate the most common image aberrations, such as tangential and sagittal astigmatism, internal and external comatic aberration, and simple geometric distortions. The model framework’s primary objective is to support small-body space mission design by allowing better simulations for characterisation of imaging instrument performance, assisting mission planning, and developing computer-vision algorithms. SISPO allows the simulation of trajectories, light parameters and camera’s intrinsic parameters.

“…The set of produced images can be implemented for 3-D surface reconstruction. The tool is open access and currently requires basic programming skills to be used [33]. The level of detail currently produced by SISPO is suitable for the design of advanced deep-space missions, the simulation of large sets of scenarios, and the development and validation of algorithms for (semi-)autonomous operations, vision-based navigation, localisation and image processing.…”
