Embodiment 1

[0030] like figure 1 As shown, it is a flow chart of an information processing method in a preferred embodiment of the present application. The information processing method can be applied to an electronic device, and the electronic device can be a robot, a mobile phone, a computer, a wearable device, a vehicle-mounted device, and the like. The information processing method includes steps as described below.

[0031] Step 101, obtaining an image of an object under test. The image can be obtained through a camera, and the camera can be a color camera or a black and white camera. When the camera is a color camera, the image is a color image, and the obtaining an image of the object under test is specifically obtaining a color image of the object under test. When the camera is a black-and-white camera, the image is a black-and-white image, and the obtaining an image of the object under test is specifically obtaining a black-and-white image of the object under test. The object...

Embodiment 2

[0049] Based on the same inventive concept, the present application also provides an electronic device 200, which may be a robot, a mobile phone, a computer, a wearable device, a vehicle-mounted device, and the like. like figure 2 As shown, the electronic device 200 includes: an image acquisition device 210 , a structured light projector 220 , a structured light camera 230 and a processor 240 .

[0050] The image acquisition device 210 is used to obtain an image of an object under test. The structured light projector 220 is used for projecting structured light to the object under test. The structured light camera 230 is used to obtain a structured light image of the object under test.

[0051] The processor 240 is used to determine at least two points to be measured on the image, and obtain the first viewing plane coordinates of the two points to be measured; The spatial coordinate set of the point and the second visual plane coordinate set corresponding to the spatial coo...

Abstract

The invention discloses an information processing method and electronic equipment. The method comprises the steps of obtaining an image of an object to be measured; determining two or more points to be measured on the image; obtaining first vision plane coordinates of the two points to be measured; obtaining a space coordinate set of all points on the object to be measured and a second vision plane coordinate set corresponding to the space coordinate sets through structured light; conducting coordinate mapping on the two first vision plane coordinates, then obtaining two second vision plane coordinates, and searching two space coordinates corresponding to the two second vision plane coordinates in the space coordinate set; according to the two space coordinates and the two second vision plane coordinates, calculating distances between the object to be measured and two points corresponding to the two points to be measured.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] As an important research branch in robotics and other research fields, ranging technology has been widely concerned. The ranging system uses sensors to perceive the depth information of the scene, thereby providing an effective basis for robots to perceive and establish three-dimensional scenes. Visual distance measurement technology is mainly divided into monocular defocus distance measurement and multi-eye stereo vision distance measurement. Among them, the monocular defocus distance measurement is to calculate the scene depth value through the blurring degree of the image edge under multiple different defocus states. This method is simple to implement, but the distance measurement accuracy is not high, and the real-time performance is poor. Multi-eye stereoscopic distance meas...
