In order to account for sensor deficiancies, usually a multi-sensor approach is used where various sensors complement each other. However, synchronization of highly accurate Global Positioning System (GPS) and video measurements requires specialized hardware which is not straightforward to set up. This paper proposes a full simulation environment for data generation and evaluation of Visual Simultaneous Localization and Mapping (Visual SLAM) and GPS based on free and open software. Specifically, image data is created by rendering a virtual environment where camera effects such as Motion Blur and Rolling Shutter can be added. Consequently, a ground truth camera trajectory is available and can be distorted via additive Gaussian noise to understand all parameters involved in the use of fusion algorithms such as the Kalman Filter. The proposed evaluation framework will be published as open source online at https://master. kalisz. co for free use by the research community.
