摘要： Systems and methods for automatic detection of defects in a coating of a component are provided. In one aspect, a coating inspection system is provided. The coating inspection system includes a heating element operable to impart heat to the component as it traverses relative thereto. An imaging device of the system captures images of the component as the heating element traverses relative to the component and applies heat thereto. The images indicate the transient thermal response of the component. The system can generate a single observation image using the captured images. The system can detect and analyze defects using the generated single observation image.

摘要： In an inspection method and apparatus, when thermal image data with respect to cap sealing of a particular container is analyzed and a low confidence score is obtained, products are classified into a user check product by a rejection-process of separating the products, without determining the products to be good products or not good products.

摘要： An additive manufacturing apparatus includes a laser and a detection system. The laser emits a laser beam to heat a powder bed to form a melt pool, and the melt pool emits light proportional to a temperature of the melt pool. The detection system includes a spectral disperser and one of a) two or more on-axis sensors or b) a line scanner. The two or more on-axis sensors or the line scanner are/is located along an axis of the emitted light, the detection system receives the emitted light from the melt pool, and an intensity of the emitted light detected by the a) two or more on-axis sensors or the b) line scanner is compared with a blackbody spectral map at a particular wavelength of the emitted light to determine a temperature of the melt pool.

摘要： A system for detecting the presence of an anomaly within a component includes a motorized apparatus configured to move around the component. The system also includes an excitation device and a camera mounted to the motorized apparatus. The excitation device is configured to emit an excitation signal toward the component to cause the anomaly within the component to generate a detectable reactionary thermal signal in response to the excitation signal. The camera is configured to capture thermal images of the component. The thermal images include the detectable reactionary thermal signal and indicate the presence of the anomaly within the component. The system further includes a controller communicatively coupled to the excitation device and the camera. The controller is configured to receive and analyze the thermal images to detect the presence of the anomaly within the component. The controller is configured to adjust one or more operating parameters of the system to affect a characteristic of the detectable reactionary signal based on the thermal images.

摘要： Suitability of silicon wafers for use in device processing without generation of fatal defects is assessed by using SIRD to measure stress in a wafer cut from a piece of a crystal ingot after first and second thermal treatments of the water, the second thermal treatment consisting of a heating phase, a holding phase, and a cooling phase. The result is used to consider whether silicon wafers cut from the piece can adequately survive device processing without generating excess defects.

摘要： A method of thermographic inspection is disclosed, including applying a thermal pulse to a surface and capturing an image of a thermal response of the surface. The image is captured with an infrared camera through a polarizer having a first orientation. The method further includes determining, by analysis of the image, whether the thermal response is indicative of a crack on the surface.

摘要： Methods, systems, and program products of inspecting solar panels using unmanned aerial vehicles (UAVs) are disclosed. A UAV can obtain a position of the Sun in a reference frame, a location of a solar panel in the reference frame, and an orientation of the solar panel in the reference frame. The UAV can determine a viewing position of the UAV in the reference frame based on at least one of the position of the Sun, the location of the solar panel, and the orientation of the solar panel. The UAV can maneuver to the viewing position and point a thermal sensor onboard the UAV at the solar panel. The UAV can capture, by the thermal sensor, a thermal image of at least a portion of the solar panel. A server onboard the UAV or connected to the UAV can detect panel failures based on the thermal image.

摘要： The present invention belongs to the technical field of constructional engineering safety detection, and provides a method for detecting hollowing of an exterior wall finish layer. The method for detecting a defect of a facade finish layer of a building proposed by the present invention can realize remote detection in the on-site detection operation and avoid high-altitude hazardous operation of personnel, and is simple and convenient in operation. In data analysis and processing, the method not only can overcome the subjectivity and the instability caused by manual color identification of a temperature image, but also can realize batch processing of image analysis through software or conduct real-time detection and analysis.
