2results about How to "Accurate distance" patented technology

The utility model relates to the field of chemical fiber production, in particular to rapid cutting equipment for chemical fiber production, which comprises a cutting table, four corners of the bottom of the cutting table are fixedly connected with supporting legs respectively, the top of a cutting table body is fixedly connected with a door-shaped frame, and the bottom of the door-shaped frame is fixedly connected with a first electric push rod. The extending end of the first electric push rod is fixedly connected with a cutting mechanism, the bottom of the cutting mechanism is transversely and slidably connected with a plurality of cutting blades capable of synchronously adjusting intervals, the two sides of the door-shaped frame are fixedly connected with pressing mechanisms correspondingly, and the front end of the top of the cutting table is fixedly connected with a traction mechanism used for pulling a carpet. According to the carpet cutting device, the distance between every two cutting blades can be more accurately adjusted, meanwhile, a carpet is pressed during carpet cutting, slipping and displacement of the carpet are avoided, and the size accuracy of the carpet after cutting is improved.

This invention discloses an object positioning system and method for near-eye displays, wherein the system includes a first imaging device and a second imaging device for respectively capturing a first image and a second image of the surrounding environment. The first imaging device and the second imaging device are provided at different spatial positions, wherein the first image and the second image include an image of a real object, and the first spatial coordinates of the real object are determined based on a dot matrix pair of receiving the image of the real object. The dot matrix pair corresponds to at least two positions of the image sensors of the first imaging device and the second imaging device, respectively. The first spatial coordinates of the real object are converted into second spatial coordinates based on the relative positions of the user and the first and second imaging devices.
