摘要： A method and apparatus for determining a distance between an optical apparatus and an object by considering a measured nonlinear waveform, as opposed to a mathematically ideal waveform. The method and apparatus may accurately calculate distance information without being affected by a type of waveform projected onto the object and may not require an expensive light source or a light modulator for generating a light with little distortion and nonlinearity. Further, since the method may be able to use a general light source, a general light modulator, and a general optical apparatus, additional costs do not arise. Furthermore, a lookup table, in which previously calculated distance information is stored, may be used, and thus the amount of computation required to be performed to calculate the distance is small, thereby allowing for quick calculation of the distance information in real time.
摘要翻译：与数学上理想的波形相反，通过考虑测量的非线性波形来确定光学装置和物体之间的距离的方法和装置。该方法和装置可以精确地计算距离信息而不受投影到物体上的波形的类型的影响，并且可能不需要昂贵的光源或用于产生具有很小失真和非线性的光的光调制器。此外，由于该方法可以使用通用光源，普通光调制器和通用光学装置，所以不会产生额外的成本。此外，可以使用其中存储先前计算出的距离信息的查找表，因此需要执行计算距离的计算量很小，从而实时地快速计算距离信息。
