Title:
METHOD AND DEVICE FOR POSITIONING OPTICAL CURVED SURFACE
Document Type and Number:
WIPO Patent Application WO/2019/100513
Kind Code:
A1
Abstract:
A device for positioning an optical curved surface comprises a transmitter (10) and a receiver (30). The transmitter (10) can transmit an optical signal to the receiver (30), and the receiver (30) can receive the optical signal transmitted by the transmitter (10). The device for positioning an optical curved surface determines the position of the receiver (30) according to the optical signal received by the receiver (30). The transmitter (10) comprises a light-emitting device (116) and a hollow hemispherical housing (115). The light-emitting device (116) can transmit optical signals with at least two flicker frequencies. The housing (115) is provided with a fixed-angle light-shading region (210) and a variable-angle light-shading region (220). A light transmissive region is arranged between the fixed-angle light-shading region (210) and the variable-angle light-shading region (220). By means of the device and the method for positioning an optical curved surface, the position of the receiver (30) can be accurately positioned, and the receiver (30) can be placed on a surface of an object to receive an optical signal of the transmitter (10), and accordingly, precise indoor positioning can be performed. In an intelligent production environment, a robot can precisely give assistance in assembling and transporting materials and products, and the positioning precision can reach a positioning requirement of up to a centimeter and even millimeter level.
