The invention belongs to the field of image processing, and discloses a photographed image processing method of an Android device, which comprises the following steps that after a camera of the Android device shoots, an HAL layer of a system obtains a video frame or a photo frame shot by the camera, calls a GPU(Graphics Processing Unit) to process the video frame or the photo frame according to apreset instruction to obtain a processed video frame or photo frame, and outputs the processed video frame or photo frame. According to the method, after a photographing APP calls a camera for photographing, the GPU is called to process the data shot by the camera in the HAL layer; a CPU does not need to be called on a JAVA layer for processing, processed data is transmitted to a photographing APP, and compared with a picture processing process of a traditional photographing APP, the picture processing method has the advantages that a hardware OPENGL directly processes an image integrally, andthe time for JAVA language to process pixels point by point through an algorithm is saved in the middle; the image processing speed and the image processing effect can be improved, and the CPU load is reduced.

The invention discloses a method for GPU-based (Graphics Processing Unit) object three-dimensional shape measurement, and belongs to the technical field of object three-dimensional measurement. The method particularly comprises the following steps: projecting structure grating to the surface of an object to be measured by a projector; shooting the surface of the object to be measured by two cameras simultaneously to obtain two groups of image sequences; storing the two groups of image sequences into computer memory; completing distortion correction, phase demodulation, corresponding points matching and three-dimensional reconstruction for the image by a GPU in parallel; transmitting the object three-dimensional coordinate obtained through three-dimensional reconstruction to the computer memory by the GPU; repeating the above steps until the measurement is complete, and releasing the GPU and the storing space. The method adopts multi-core GPU to realize the parallel calculation at thread level, greatly increases data processing speed, and can satisfy the real-time requirement for three-dimensional measurement of a dynamic object.

The invention discloses a method, a system and a device for monitoring a GPU (graphics processing unit) by a BMC (baseboard management controller) as well as a storage medium. The method comprises thesteps as follows: the BMC in a server sends a reading instruction every other preset time, so that the GPU in the server collects current GPU information after receiving the reading instruction; theBMC monitors the GPU according to the current GPU information. The BMC regularly sends the reading instruction to the GPU every other set time. The GPU begins to collect the current GPU information reflecting the current performance of GPU or other information after receiving the reading instruction and sends the current GPU information to the BMC. Then, the BMC monitors the GPU according to the current GPU information. Therefore, a maintainer is not required to install drive and related monitoring software of the GPU, the monitoring process is simplified, and the monitoring efficiency is improved. The BMC can regularly and automatically acquire the GPU information and automatically monitor the state of the GPU and is relatively intelligent.
