Abstract

The present invention discloses testing 3D imaging systems. Methods, systems, and apparatus include computer programs encoded on a computer storage medium and relate to testing three-dimensional imaging systems. In some implementations, a system includes a mount for a three-dimensional camera, a mount for a calibration target, and a rail to which the mount for the calibration target is coupled. The movement of the mount for the calibration target is constrained to the direction extending along the rail. The system includes a processing device having logic that receives a reading from a particular three-dimensional camera coupled to the mount for the three-dimensional camera. The reading includes a distance from the three-dimensional camera to a particular calibration target coupled to themount for the calibration target. The logic receives a measurement result of an actual distance from the particular three-dimensional camera to the particular calibration target. The logic then provides measurement characteristics of the particular three-dimensional camera.

Description

technical field [0001] This specification relates to testing three-dimensional (3D) imaging systems. Background technique [0002] Currently, there is no industry standard for benchmarking the performance of 3D imaging systems. Different 3D imaging systems can offer performance improvements of various characteristics. 3D imaging systems are typically evaluated based on three metrics: noise and uniformity, sharpness and frequency response, and motion artifacts. Contents of the invention [0003] A depth imaging system, range imaging system, or 3D imaging system produces a 2D image showing the distance from a particular point to a point in the image. This point is usually associated with the imaging system's depth sensor or camera. The resulting image has pixel values ​​corresponding to distances. When the system's sensors are properly calibrated, pixel values ​​can be given directly in physical units, such as meters. [0004] According to one general implementation, a ...
