The invention discloses a spatial positioning system and method, positioning equipment and an optical sensor module. The spatial positioning system comprises the positioning equipment, N optical sensor modules and a master controller. The positioning equipment is provided with an optical scanning device. The N optical sensor modules are arranged in a space with positioning to be performed, and each optical sensor module comprises M optical triggers. The optical scanning device is used for generating scanning rays in a first direction and scanning rays in a second direction, wherein the first direction and the second direction intersect. The optical triggers are used for generating electrical signals under the action of the scanning rays. The master controller is used for determining the position of the positioning equipment in the space with positioning to be performed according to the electrical signals generated by at least three non-collinear optical triggers. According to the scheme, the characteristic that light is propagated in straight lines and the photo-electrical effect are utilized, the precision of spatial positioning is improved to the centimeter level from the meter level, and the higher and higher requirement of people for the spatial positioning precision is met.
Description
Technical field [0001] The present invention relates to the field of spatial positioning, in particular to a spatial positioning system and method, positioning equipment and light sensor modules. Background technique [0002] Spatial positioning refers to the location of a designated device in space. For example, the location of the device can be determined through GPS (English: Global Positioning System; Chinese: Global Positioning System) technology. However, as people's requirements for positioning accuracy are getting higher and higher, the meter-level accuracy provided by GPS technology can no longer meet people's needs, and in some specific spaces such as indoors, basements, etc., the GPS will be blocked by obstacles such as walls. Signal, so GPS technology cannot be applied in these specific spaces. [0003] At present, in specific spaces such as indoors and basements, wireless positioning technology is generally used to locate, specifically based on the device receiving mu...
