We present a photo-realistic training and evaluation simulator (Sim4CV) with extensive applications across various fields of computer vision. Built on top of the Unreal Engine, the simulator integrates full featured physics based cars, unmanned aerial vehicles (UAVs), and animated human actors in diverse urban and suburban 3D environments. The simulator fully integrates both several state-of-the-art tracking algorithms with a benchmark evaluation tool and a generic deep neural network (DNN) interface for real-time evaluation. It generates synthetic photo-realistic datasets with automatic groundtruth annotations to easily extend existing real-world datasets and provides extensive synthetic data variety through its ability to reconfigure synthetic worlds on the fly using an automatic world generation tool.
