摘要： 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.

摘要： A camera apparatus, e.g., a stereoscopic camera apparatus, includes a dual element mounting plate, a pair of individual lens mounts, and a pair of sensor holders, each sensor holder holding an image sensor. The lens mounts and sensor holders are secured to the dual element mounting plate. Multiple dual element mounting plates corresponding to camera pairs may be secured to a base plate. Various features facilitate achieving and maintaining alignment between a lens and a corresponding image sensor, as well as between camera pairs and between sets of camera pairs.

摘要： A camera apparatus, e.g., a stereoscopic camera apparatus, includes a slideable filter plate inserted into a slot in a dual element mounting plate. The slideable filter plate includes a plurality of selectable pairs of filter mounting positions and changes between pairs of filter mounting positions may be performed without altering camera alignments. Each pair of filter mounting positions includes a right eye filter mounting position and a left eye filter mounting position. Each pair of filter mounting positions in the slideable filter plate includes a pair of filters or no filters.
