ABSTRACT
A multi-object distance determination method can be achieved by 932â
nm structured light with one camera as the data receiver. The structured light generated by a liquid crystal on silicon spatial light modulator (LCoS-SLM) facilitates dynamic image projection on targets. A series of moving light strip images were captured and collected for data analysis. This method lifted the limitation of single-object distance determination and the limitation of the angle requirement between the camera and the light source in the triangulation method. The average error of this method was approximately 3% in the range of 700 mm to 1900â
mm away from LCoS-SLM without further optimization. It provides a potential compact design for indoor multi-object distance determination in the future.
