Abstract

The invention discloses a light detection method and device, and a computer readable storage medium. The light detection method comprises the steps of obtaining a screen projection image of a light plane, wherein the screen projection image is a light band; and calculating at least one of the following attributes of the light band: the length, the width and the radian, and comparing the calculatedattribute with a preset threshold value so as to detect whether the light plane is qualified or not. According to the light detection method and device, the at least one of the attributes, includingthe length, the width and the radian, of the screen projection image of the light plane is compared with the preset threshold value, so that whether the light plane is qualified or not can be detectedvery simply and rapidly.

Description

technical field [0001] The present invention relates to the technical field of light detection, in particular to a light detection method and device, and a computer-readable storage medium. Background technique [0002] In recent years, technologies and industries related to location services are developing indoors, especially in the fields of virtual reality (VR) and augmented reality (AR), where location technology has become the basis for interaction between VR and AR. Existing positioning technologies in the field of VR and AR include: infrared optical positioning, laser positioning, ultrasonic positioning and visible light positioning. In order to increase the user experience, it is also necessary to cooperate with devices such as handles or gloves to transmit the user's actions in reality to the virtual world and interact with them, such as archery and drawing. [0003] The use of laser positioning usually requires optical components, such as lenses, mirrors, etc., to...
