Abstract: A device for measuring length and center of mass of conical workpiece, including an inner frame, an outer frame, a base plate, two laser displacement sensors and a plurality of weighing mechanisms. The inner frame is rotatably connected with the outer frame through a pin shaft. A bottom surface of the conical workpiece can be fixedly connected with an inner bottom surface of the inner frame. The base plate is removably arranged on the inner frame, and abuts against a top of the conical workpiece. The base plate is perpendicular to an axis of the conical workpiece. The laser displacement sensors are fixedly arranged at a position of the inner frame below the top of the conical workpiece. The weighing mechanisms are provided at a bottom of the outer frame, and can bear the inner frame, the outer frame and the conical workpiece.

Abstract: A sky filter method for panoramic images and a portable terminal is provided. The method comprises: obtaining several panoramic images containing sky regions as a data set, and marking a sky region and a ground region of each panoramic image to obtain a marked mask image and a panoramic template image of sky; extracting features of the sky region and the ground region of each panoramic image, and marking a positive sample and a negative sample; inputting the positive sample and the negative sample to SVM for training to obtain a model; extracting the features of the panoramic images, and inputting same to the model to obtain an initial mask image; removing a misclassified pixel and a misclassified region in the initial mask image to obtain an accurate mask image; and fuse the panoramic template image of sky and a test panoramic image to achieve a sky filter effect.

Abstract: The present invention provides a generation method for a 3D asteroid dynamic map and a portable terminal. The method comprises: obtaining a panorama image; identifying the panorama image and segmenting into a sky region, a human body region, and a ground region; calculating a panoramic depth map for the sky region, the human body region, and the ground region; respectively transforming the panorama image and the panoramic depth map to generate an asteroid image and an asteroid depth map; generating an asteroid view under a virtual viewpoint; and rendering to generate a 3D asteroid dynamic map. By automatically generating the asteroid view under the virtual viewpoint, and synthesizing and rendering same, the technical solution of the present invention generates the asteroid dynamic map having a 3D effect from the panorama image.
