Title:
OPTICAL DISTANCE MEASUREMENT METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/076072
Kind Code:
A1
Abstract:
Provided is an optical distance measurement apparatus (11). The apparatus comprises a light emitter (101) used for emitting light to a target object; a light receiver (102) used for receiving reflected light after the light is emitted to the target object, and the light receiver (102) comprises a lens (1021) and a planar array-type image sensor (1022), wherein the planar array-type image sensor (1022) includes a photosensitive area (401), and the photosensitive area (401) is divided into one or more photosensitive sub-areas, and the one or more photosensitive sub-areas are used for collecting one or more light points of the reflected light, and the light receiver (102) is further used for generating a response signal, and the response signal comprises position information (1, 2,....., N) about one or more reflected light points; and a processor (103) used for receiving the response signal generated by the light receiver (102), and using a triangle method to calculate the distance between the target object and the optical distance measurement apparatus (11) according to the position information about the reflected light points. The present optical distance measurement apparatus effectively reduces the cost, improves the sampling density, and also improves the fault tolerance degree of installation errors.
