一種基於等距長方投影的全景地圖的處理方法,包括:擷取多數個環境影像,且產生等距長方投影全景影像;若判斷三維稀疏點地圖需要被更新,輸出 三維稀疏點地圖;若判斷三維稀疏點地圖不需被更新,根據水平角度將等距長方投影全景影像進行即時地透視轉換,產生透視影像;自透視影像萃取出多數個地圖特徵點,若已成功追蹤連續兩幀的多數個地圖特徵點,輸出相機姿態資訊。本發明更包括一種基於等距長方投影的全景地圖的處理模組。 A processing method of panoramic view based on equirectangular projection includes steps as follows. Capturing a plurality of environmental images and generating an equidistant rectangular projection panoramic image. If the equirectangular projection panoramic image needs to be updated, outputting a three-dimensional sparse point map. If the equirectangular projection panoramic image does not need to be updated, the equirectangular projection panoramic image is instantly perspective-transformed according to a horizontal angle to generate a perspective image. Extracting a plurality of map feature points from the perspective image. If the plurality of map feature points of two consecutive frames have been successfully tracked, outputting camera pose information. The present disclosure further includes a processing module of panoramic view based on equirectangular projection.
