Abstract: A soldering process method includes the following steps. A temperature profile of generating a solder structure is measured. A final product of the solder structure is tested and recorded. A machine learning method is used to repeatedly compare and analyze a relationship between a plurality of the temperature profiles of the solder structure and a corresponding final product of the solder structure so as to find an optimal temperature profile model in accordance with quality control requirements.

Abstract: An automatic robotic arm system and a coordinating method for robotic arm and computer vision thereof are disclosed. A beam-splitting mirror splits an incident light into a visible light and a ranging light and respectively guides to an image capturing device and an optical ranging device arranged in the different reference axes. In a calibration mode, a transformation relation is computed based on a plurality of the calibration postures and corresponding calibration images. In an operation mode, a mechanical space coordinate is determined based on an operation image and the transformation relation, and the robotic arm is controlled to move based on the mechanical space coordinate.

Abstract: An image positioning system based on upsampling and a method thereof are provided. The image positioning method based on upsampling is to fetch a region image covering a target from a wide region image, determine a rough position of the target, execute an upsampling process on the region image based on neural network data model for obtaining a super-resolution region image, map the rough position onto the super-resolution region image, and analyze the super-resolution region image for determining a precise position of the target. The present disclosed example can significantly improve the efficiency of positioning and effectively reduce the required cost of hardware.

Abstract: A system for detecting electronic components includes a light-source device, a photography device, an adjustment device, and an image-processing device. The light-source device generates a light to illuminate at least one pin of a first electronic component at different rotation angles. The photography device senses the light and generates first and second images corresponding to the pin of the first electronic component at different rotation angles. The adjustment device adjusts the photography device and the light-source device to a first height and a second height, wherein the first images correspond to the first height and the second images correspond to the second height. The image-processing device calculates first feature information of the pin of the first electronic component according the first and second images, and analyzes the state of the pin of the first electronic component according to the first feature information.
