    • A plurality of images, including a first image and a second image having a higher resolution than the first image, are aligned by generating an oversampled cross correlation image that corresponds to relative displacements of the first and second images, and, based on the oversampled cross correlation image, determining an offset value that corresponds to a misalignment of the first and second images. The first and second images are aligned to a precision greater than the resolution of the first image, based on the determined offset value. Enhanced results are achieved by performing another iteration of generating an oversampled cross correlation image and determining an offset value for the first and second images. Generating the oversampled cross correlation image may involve generating a cross correlation image that corresponds to relative displacements of the first and second images, and oversampling the cross correlation image to generate the oversampled cross correlation image.
    • 通过产生对应于第一和第二图像的相对位移的过采样互相关图像,并且基于过采样交叉,对准包括具有比第一图像更高分辨率的第一图像和第二图像的多个图像 相关图像,确定对应于第一和第二图像的未对准的偏移值。 基于所确定的偏移值,将第一和第二图像对准到大于第一图像的分辨率的精度。 通过执行产生过采样互相关图像的另一次迭代并确定第一和第二图像的偏移值来实现增强的结果。 产生过采样互相关图像可以涉及产生对应于第一和第二图像的相对位移的互相关图像,并且对互相关图像进行过采样以生成过采样互相关图像。

    • The invention is a versatile school bus traffic control system. When power is first applied, or the RESET pushbutton is pushed, it is set to its quiescent state. Pushing the MODE ADVANCE pushbutton switch will advance to the next state: flashing alternating yellow traffic control lights. The next push of MODE ADVANCE will advance the system to: flash traffic control lights, one side red and the other side yellow, next, the complementing red and yellow. This is repeated for approximately three seconds, next, automatically advancing to only alternating red traffic control lights flash, until MODE ADVANCE is again pushed. The invention then returns to quiescence. Optionally, the invention will reset, and or not respond to MODE ADVANCE if the school bus is in motion.
    • 本发明是一种多功能的校车交通控制系统。 首次施加电源或按下RESET按钮时,将其设置为静止状态。 按MODE ADVANCE按钮开关将进入下一个状态:闪烁交替黄色交通控制灯。 接下来的MODE ADVANCE将推进系统:闪光灯控制灯,一面红色,另一面黄色,接下来,补充红色和黄色。 重复约三秒钟,接下来,自动前进到交替的红色交通控制灯闪烁,直到再次按下MODE ADVANCE。 然后,本发明回到静止状态。 可选地,如果校车运动,本发明将重置,或者不对MODE ADVANCE作出响应。
