Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as figure 1 As shown, the camera relocation method based on semantic landmarks of the present invention comprises the following steps:
[0031] Step 1: Arrange semantic landmarks on the ground of the working scene of the camera, and store the coordinates of the center point of each semantic landmark in the SLAM system to form a scene map.
[0032] In this example, if figure 2 As shown, the working scene is a corridor with a length of 200 meters, and the method of arranging semantic signposts is to arrange a semantic signpost every 50cm. Among them, semantic landmarks are markers with obvious characteristics, such as image 3 shown.
[0033] Step 2: Initialize the ground preselection area.
[0034] In this example, if Figure 4 As shown in , the white box part is the projection of the ground in the camera image coordinate syst...
