Methods of determining whether an environment is suitable or acceptable for performing a three-dimensional (3D) scan are provided. The methods may include performing one or more checks on captured image data of the environment, wherein performing each of the one or more checks comprises determining whether the environment satisfies a respective criterion. The method may further include determining that the environment is suitable or unsuitable for performing the 3D scan based on a result of each performed check. Determining that the environment is suitable for performing the 3D scan may include determining that the environment satisfies each of the respective criteria of the performed one or more checks. Determining that the environment is unsuitable for performing the 3D scan may include determining that the environment does not satisfy at least one criterion of the performed one or more checks. Related devices and computer program products are also provided.

A method for estimating a 3D map and a plurality of poses is described. The method includes non-recursively performing an initialization of the 3D map and the respective poses of the plurality of poses based on a plurality of first 2D images of the series of 2D images, and recursively performing sequential updating of the 3D map based on recursively updating the 3D map for respective ones of a plurality of second 2D images of the series of 2D images. Related systems, devices and computer program products are also described.
