Proposed are an arrangement and a method for depth-scanning strip triangulation with internal or external depth scan, particularly also for the 3D shape measurement in microscopy and mesoscopy. The robustness of the measurement with wavelet signal generation from an image stack is to be increased. The occurrence of the known and very undesirable 2Pi phase jumps in the phase map is to be avoided as much as possible. To do this, with a measurement instead of a wavelet at least two wavelets with contrast envelope are generated. This is done by a concurrentthen preferably with spectral separationor by a sequential projection of two strip images with different triangulation wavelengths on the measured object.

Embodiments of the present invention disclose a building height calculation method, device, and storage medium. The method includes: acquiring an original picture including an image of a building; projecting the original picture to a surface of a preset sphere to form a projected picture; performing an edge detection on the image of the building in the projected picture to acquire a pixel height of the building; determining a projection angle of the projection on the preset sphere based on the pixel height of the building; and determining a height of the building based on the projection angle and a distance between the building and a capturing position of the original picture. In the embodiments of the present invention, a projection angle of a building is determined based on an original picture including an image of the building, and the height of the building is determined based on the projection angle and a distance between the building and a capturing position of the original picture. Hence, the height of the building can be obtained automatically and quickly based on the picture without manual involvements, thus reducing the cost of acquisition while improving the acquisition efficiency.

The disclosure relates to an arrangement and a method for capturing coordinates of an object surface by triangulation. At least two partial light patterns are generated representing a decomposition of a corresponding basic light pattern. The partial light patterns are separately projected onto the object surface, an image of the object surface is captured during the projection of one of the partial light patterns, and components of the total intensity of the captured images are ascertained. A balance of direct and indirect intensity components is established per image and for each pixel under the assumption that the indirect intensity components in all images are equal. A reflection image is established based on the direct and/or indirect intensity components which approximates the image that would be capturable during a projection of the basic light pattern without indirect intensity components. Based on the reflection image, coordinates of the object surface are ascertained.

As an autonomous vehicle moves through a local area, pairwise alignment may be performed to calculate changes in the pose of the vehicle between different points in time. The vehicle comprises an imaging system configured to capture image frames depicting a portion of the surrounding area. Features are identified from the captured image frames, and a 3-D location is determined for each identified feature. The features of different image frames corresponding to different points in time are analyzed to determine a transformation in the pose of the vehicle during the time period between the image frames. The determined poses of the vehicle are used to generate an HD map of the local area.
