The present invention relates to the technical field of measurement, and in particular, relates to an object measurement method based on structured light, and an electronic device. The method is applied to the electronic device, and comprises the steps: acquiring a projection image which is an image corresponding to the projection of the structured light onto an object, wherein the structured light comprises a plurality of stripe patterns arranged in a preset order; determining the width of the edge stripe pattern projected and covering the edge of the object and the pattern positions of the adjacent stripe patterns adjacent to the edge stripe pattern at the structured light according to the projection image; measuring the scanning angle of the object according to the width of the edge stripe pattern, the pattern positions of the adjacent stripe patterns in the structured light, and a scanning angle formula. When measuring the position of the object, the electronic device projects thestructured light to the object, and the measuring speed is fast, and the optical component does not need to be rotated. Relatively speaking, the method reduces the measurement errors caused by the mechanical motion, and the measurement is reliable.
Description
technical field [0001] The invention relates to the field of measurement technology, in particular to an object measurement method and electronic equipment based on structured light. Background technique [0002] Sweeping robots are widely used in family rooms. They can sense the surrounding environment, navigate autonomously, avoid obstacles, and carry out cleaning work autonomously according to the planned route. [0003] When the sweeping robot avoids obstacles, it is necessary to measure the specific position of the obstacle. For example, the traditional technology uses laser ranging. Specifically, the laser ranging device includes a laser transmitter, a mechanical drive mechanism, and an image acquisition device. The mechanical drive mechanism drives the laser transmitter. Scan the front environment, the image acquisition device collects the returned laser line, and analyzes the distance between the obstacle and the laser distance measuring device according to the retur...
