Technical field
The present invention relates to a kind of high-resolution three-dimension interference type imaging spectrum image space two dimension fast display method.
Background technology
High-resolution image spectrometer has high spatial resolution and temporal resolution, will produce mass data in imaging process, is the data cube with interference information.Real-time demonstration and processing to these data are played great function to the utilization of high-resolution imaging data.
The normal law of conservation of energy that adopts in the Fourier transform of space two-dimension image demonstration that interference type imaging spectrum is looked like to be converted to the geographic position, the interference information that is about to certain geographical positional information in the interference image is calculated gross energy, with the gray-scale value of this value as corresponding geographic position.The specific algorithm that the interference information gross energy calculates is that the each row of data with interference image all carries out quadratic sum and asks arithmetic square root again, this algorithm is if be applied to the magnanimity computing especially of high-resolution imaging data computation amount, cause that memory consumption is big, processing speed is slow, can't realize that fast two-dimensional shows.
Summary of the invention
The object of the invention provides a kind of high-resolution three-dimension interference type imaging spectrum image space two dimension fast display method, and it has solved the technical matters that conventional images two dimension display packing memory consumption is big, processing speed is slow.
