Embodiment 1

[0036] This embodiment is a projection method for an intelligent projection robot, wherein the intelligent projection robot is provided with a projection module that can move along the robot body and a camera module fixed on the intelligent robot body, wherein the projection module uses DLP projection technology for projection, The minimum size of the projection screen is 20 inches and the maximum is 120 inches. The projection distance between the intelligent projection robot and the projection wall is at least 1 meter and the maximum is 4 meters. The acquisition resolution of the module is also 1920*1080. Such as image 3 As shown, 5 projection positions are obtained, and the projection position is Y 0 , Y 1 ,...,Y i Indicates that i=4.

[0037] In this embodiment, the intelligent projection robot automatically adapts the projection area and the method for auto-focusing, such as figure 1 and figure 2 shown, including the following steps:

[0038] 1) moving the robot i...

Embodiment 2

[0062] Such as Figure 4 As shown, this embodiment is a robot using the projection method described in Embodiment 1, including a projection module, a camera module, a ranging module, a light sensing module, a control module and a moving module; the projection module can move along the robot body , for projecting the image onto a designated projection wall; the camera module is fixed on the robot body for taking images of the projection wall; the distance measuring module is used for measuring the distance from the robot to the projection wall; the light The sensing module is used to measure the brightness of the ambient light; the mobile module is used to move the robot and the projection module; the control module is used to determine the best projection position according to the image taken by the camera module, control the moving distance of the mobile module, adjust the brightness of the projection module and automatically focus on the projection module.

Abstract

The invention discloses a projection method for an intelligent projection robot, and a robot employing the projection method. The method comprises the steps: firstly carrying out the row algorithm calculation of a region where a user needs to carry out projection according to a camera module, and determining an optimal projection position and an actual projection image; calculating the proper movement distances of the robot and the projection module according to the position of the actual projection image in imaging, carrying out the analysis and calculation of the contrast ratio of the image, feeding results back to the projection for automatic focusing, and carrying out automatic brightness adjustment through the brightness of current ambient light. The robot comprises a projection module, a camera module, a distance measurement module, a light sensing module, a control module, and a movement module. The method can automatically determine the optimal projection position, can carry out automatic focusing, can automatically carry out brightness adjustment, and brings excellent user experience.

Description

technical field [0001] The invention relates to a method for an intelligent projection robot to automatically adapt a projection area and automatically focus, and belongs to the technical field of intelligent projection robots. Background technique [0002] With the development of intelligent robots, the projection function has become an indispensable function of intelligent robots and home entertainment robots. The main task of the intelligent projection robot is home entertainment. It has built-in projection function and various multimedia functions. It can move from one room to another, and can project and play audio and video anytime and anywhere. It can solve the problems of many traditional projectors. Inconvenience caused. [0003] However, if the existing intelligent projection robot needs to project in different places and in different scenes according to the user's wishes, it is still necessary to manually adjust the position and size of the projection area of ​​t...
