Document Type and Number:
WIPO Patent Application WO/2017/206571
Kind Code:
A1
Abstract:
A target positioning method using laser scanning and a laser receiving apparatus (700) are provided. The target positioning method using laser scanning comprises: the laser receiving apparatus (700) recording a first time when a synchronization signal transmitted by a first laser rotary scanning apparatus is received and a second time when a laser signal is received; determining a receiving duration and determining a rotational angle of the first laser rotary scanning apparatus according to the receiving duration; determining a position of the laser receiving apparatus (700) (identical to a position of a target object) according to rotational angles of N laser rotary scanning apparatuses, wherein the first laser rotary scanning apparatus is any one of the N laser rotary scanning apparatuses of a laser emitting apparatus, and N is greater than or equal to 3. According to the method and the apparatus of the present invention, only three laser rotary scanning apparatuses are required to position the laser receiving apparatus (700), light, equipment, and power demand is low, and only at least one laser sensitive element (603) is required within the laser receiving apparatus (700), therefore a less complicated apparatus structure is achieved.
