Abstract
Techniques for identifying a 3D feature represented in images in a buffer are disclosed. The images comprise a first and second image, and the images provide data that is usable to determine a depth for the 3D feature. A 2D feature point that is an observation of the 3D feature is identified. A pseudo measurement is computed for the 2D feature point. This measurement includes a depth and an uncertainty value. A first joint uncertainty is determined for the depth using the pseudo measurement. The first image is ejected from the buffer, resulting in a reduction to an amount of the data that is usable to determine the depth. The pseudo measurement is tuned until a resulting second joint uncertainty, which is based on the pseudo measurement, is within a threshold level of similarity to the first joint uncertainty.
