摘要： Phase-based TOF systems operate with reduced depth error due to motion blur, and/or spatial blur, and/or pixel offset by intelligently determining how best to combine pixel values, and how best to compensate for individual pixel offsets. Such determination(s) may be carried out on a per pixel basis, dynamically, in real-time during TOF operation, or on archived TOF data. Offsets for individual pixels may be dynamically calculated and subtracted from the values acquired by those pixels Individual pixel offsets may be calculated for example by combining data acquired by the same pixel at two acquisitions, 180° out of phase with respect to each other. Calculated offsets may be averaged, or on a per pixel basis, and if target object motion is detected, one or more offset calculations can be discarded rather than averaged to reduce motion blur. Offsets acquired a priori during a TOF system calibration procedure may be used.
摘要翻译：基于相位的TOF系统通过智能地确定如何最佳地组合像素值，以及如何最佳地补偿各个像素偏移，由于运动模糊和/或空间模糊，和/或像素偏移而减小深度误差。这样的确定可以在TOF操作期间或在存档的TOF数据上以动态方式在每像素的基础上进行。可以动态地计算各个像素的偏移量并从由这些像素获取的值中减去。例如，可以通过将由相同像素获取的数据在两次采集中相对于彼此相位相差180°而组合来计算各个像素偏移。计算的偏移量可以被平均，或者基于每个像素，并且如果检测到目标物体运动，则可以丢弃一个或多个偏移计算而不是平均以减少运动模糊。可以使用在TOF系统校准过程中先验获得的偏移。

摘要： A phase-based TOF system is operated with N≧3 modulation frequencies fi. These frequencies can be changed during N time intervals that together define an exposure time for the TOF pixel array. Preferably N=3 and modulation frequencies f1, f2, f3 are used, where f1=αm1, f2=αm2, and f3=αm3, where m1, m2, and m3 are small integers co-prime to each other, and a is a coefficent. A first phase image is acquired during perhaps the first third of exposure time using f1, then for the next third of exposure time a second phase image is acquired using f2, and then f3 is used to acquire a third phase image during the last third of exposure time. Geometric analysis yields desired values for m1, m2, and m3 to unwrap and thus disambiguate phase. Identification of valid and invalid data is identified using dynamically adjustable error tolerances.
摘要翻译：基于相位的TOF系统以N> = 3调制频率fi运行。这些频率可以在N个时间间隔期间改变，这些时间间隔共同定义了TOF像素阵列的曝光时间。优选N = 3，并且使用调制频率f1，f2，f3，其中f1 = alpham1，f2 = alpham2和f3 = alpham3，其中m1，m2和m3是彼此共同的小整数，a是系数在使用f1的曝光时间的第一三分之一期间获取第一相位图像，然后在曝光时间的下一个三分之一中，使用f2获取第二相位图像，然后使用f3来获取第三相位图像的最后三分之一曝光时间。几何分析产生m1，m2和m3的期望值以展开并因此消除相位差。使用动态可调的误差公差识别有效和无效的数据。

摘要： A chord playing attachment and related method is disclosed. The chord playing attachment may be attached to a guitar or similar stringed instrument, and the user may use the chord playing attachment to learn to play the instrument. Unlike other chord playing attachments, the present invention discloses a design that does not function as a capo, which allows the user play chords in standard keys. The present invention also discloses tabs that may be removed or swapped by the user to allow the user to play some chords by pressing the strings directly and some by pressing a finger pad. The present invention encourages novices to learn to play the instrument in stages and eventually remove the invention entirely. A companion teaching manual is also disclosed.

摘要： A phase-based TOF system preferably generates an optical waveform with fast rise and fall times, to enhance modulation contrast, notwithstanding there will be many high order harmonics. The system is preferably operated with an odd number of phases, to reduce system bias error due to the higher order harmonics, while maintaining good modulation contrast, without unduly increasing system memory requirements. Preferably the system can dynamically calibrate (and compensate for) higher order harmonics in the TOF generated optical energy waveform, over time and temperature. Within the optical energy transmission channel, or within the optical energy detection channel, detection amplifier gain may be modified, and/or detector signal integration time may be varied, and/or digital values may be employed to implement calibration and error reduction The resultant TOF system can operate with improved phase-vs-distance characteristics, with reduced calibration requirements.
