Common depth point. Things To Know About Common depth point.

process assigns each trace to a single shot, receiver, common depth point, inline, crossline, and offset bin. Other individual values for each trace, shot, receiver, CDP, and offset bin are also computed. The first step in the Geometry Assignment process, the description of the field geometry, can actually be accomplished using a number of ... Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. Timing comparisons show that this method is faster than the conventional FFT technique demonstrated by Gold and Rader. In addition, it permits a shorter word length, smaller memory size, and is well suited to seismic data processing. Application of this method to common-depth-point trace summation ('stacking') is illustrated.Jan 21, 2020 · 1.点云数据转激光数据 (有一个包叫depthimage_to_laserscan),来减少信息量。.
