System and method for realizing real-time data point mapping processing based on three-dimensional checking

Abstract

The invention relates to a system and a method for realizing real-time data point mapping processing based on three-dimensional checking, and belongs to the technical field of image data processing. According to the system, firstly coordinates of four peaks of a tetrahedron to which an input point belongs is determined, secondly a corresponding relationship of four one-dimensional checking tables and the peaks of the tetrahedron is determined through a three-dimensional to one-dimensional address mapping module; four one-dimensional checking table modules respectively obtain data (with appointed positions) of the address from an internal storage space according to respective obtained one-dimensional address; and finally an output internal inserting value is calculated by a tetrahedron internal inserting module so as to realize the real-time mapping processing to an image data point. The system and the method provided by the invention are relatively low in error rate and relatively good in performance under the condition of the one-dimensional checking table modules with same capacity; and under the condition of the same error rate, a required one-dimensional checking table module is relatively small in capacity, relatively low in requirements on hardware and relatively small in complexity; and meanwhile, the system and the method have relatively high throughput rate, are convenient in realization mode, low in cost and relatively wid in application range.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to the technical field of data processing based on a lookup table, and specifically refers to a system and method for realizing real-time mapping processing of data points based on a three-dimensional lookup table. Background technique [0002] In the technical field of image or other data processing using embedded systems, look-up tables are often called LUTs (look-up tables), which link index numbers with output values. A color table is a common LUT used to determine the colors and intensities to be displayed for a particular image. LUTs usually use a RAM. After the RM writes the data into the RAM in advance, whenever a signal is input, it is equivalent to inputting an address to look up the table, find out the content corresponding to the address, and then output the corresponding pixel color and intensity. [0003] Three-dimensional look-up table (3D LUT) can r...

Problems solved by technology

However, although diagonal interpolation in a specific direction has good performance on average, the implementation of this method can only achieve a mixture of diagonal interpolation in 4 directions due to the limitation of the hardware architecture, which affects its performance. Error performance, so in the end you can only get comparable performance to trilinear interpolation
