Abstract

A method for increasing speckle spot density, comprising: acquiring light splitting dot array, which is used for performing array copying on multi-point light source and projection to form speckle spot array; acquiring minimum neighboring point spacing or average value of neighboring point spacing of all or part of light-emitting points in the multi-point light source; dividing light splitting dot array into first light splitting dot array and second light splitting dot array, speckle spot array formed by projection by first light splitting dot array being located in first speckle spot area, and speckle spot array formed by projection by second light splitting dot array being located in second speckle spot area; and performing expansive copying on each light splitting dot in second light splitting dot array so as to form third light splitting dot array.
