Problems solved by technology

The main defects are: 1. It is troublesome, time-consuming and low-precision to measure the side length manually with a tape measure
2. The projection screen is actually an irregular quadrilateral. For the convenience of calculation, only the average value of the side lengths is multiplied. This place will introduce human error

Abstract

The present invention relates to the field of projection technology, and the embodiments specifically disclose a method, device and readable storage medium for obtaining projection standard brightness. The method for obtaining the projection standard brightness provided by this application adopts the method of collecting the projected picture image, and calculates the side length of the projected picture according to the coordinate transformation relationship between the projection surface and the projection surface image; divides the projected picture into two triangles, and calculates the side length of the projected picture according to the projection picture Calculate the area of ​​the two triangles by the side lengths, and sum the areas of the two triangles to obtain the projected screen area; obtain the central point illuminance and brightness average coefficient; calculate the standard brightness of the projection according to the center point illumination, projected screen area, and brightness average coefficient The method uses an automatic measurement method to replace the method of manually measuring the area of ​​the projection screen, and achieves fast and high accuracy in obtaining the projection standard brightness.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a method, device and readable storage medium for obtaining projection standard brightness. Background technique [0002] In the prior art, the area of ​​the projection screen must be measured to obtain the projection standard brightness. To measure the area of ​​the projection screen, generally use a tape measure to measure the lengths of the four sides of the projection screen. . The main defects are as follows: 1. It is troublesome, time-consuming and low-precision to manually use a tape measure to measure the side length. 2. The projection screen is actually a trapezoid. For the convenience of calculation, only the average value of the side lengths is multiplied. This place will introduce human error. Therefore, there is an urgent need to provide a convenient and accurate method for obtaining projection standard brightness. Contents of the invention [0003] I...
