Abstract
Methods and apparatus for aligning components of camera assemblies of one or more camera pairs, e.g., a stereoscopic camera pairs, are described. A camera calibration tool referred to as a camera bra is used. Each dome of the camera bra includes a test pattern, e.g., grid of points, with the domes being aligned and spaced apart by a predetermined amount. The bra is placed over the cameras of a camera pair, the grids are detected and displayed. The camera component positions are adjusted until the displayed images show the grids as being properly aligned. Because the grids on the calibration tool are properly aligned as a result of the manufacturing of the calibration tool, when the images are brought into alignment the cameras will be properly spaced and aligned at which point the calibration tool can be removed and the stereoscopic camera pair used to capture images of a scene.
