The invention is applicable to the distance measurement field and provides a method and a device for measuring space distances. The method is realized on the basis of a first light emission module and a second light emission module which can emit visible light. The method comprises steps that the first light emission module is controlled for emitting a first light beam to a first space point, and the first light beam is perpendicular to a connection line of the first light emission module and the second light emission module; the second light emission module is controlled for emitting a second light beam to the first space point, and the first light beam and the second light beam are made to cross at the first point; a first included angle of the second light beam and the connection line is acquired, and a distance between the first point and the first light emission module is calculated according to length of the connection line and the first included angle. The method is advantaged in that a distance between a point in the space and a light beam emission source can be calculated, measurement precision is high, the method is especially suitable for measuring spatial objects in relatively short distances, operation is simple, the method is easy to realize, and the method is suitable for wide popularization.
Description
Technical field [0001] The invention belongs to the field of distance measurement, and in particular relates to a method and device for measuring spatial distance. Background technique [0002] With the continuous advancement of science and technology, various ranging methods emerge in endlessly. At present, the main ranging methods include laser ranging and ultrasonic ranging, which provide convenience for measuring the distance between space objects. [0003] However, the existing laser ranging and ultrasonic ranging both calculate the distance by detecting the time difference between the transmitted signal and the reflected signal. The measurement accuracy of the distance is related to the detection accuracy of the time difference, and the error is large, especially not suitable for the measurement. Close space distance. Summary of the invention [0004] The purpose of the present invention is to provide a method and device for measuring spatial distance, aiming to solve the pro...
