Abstract: An image processing device includes: a reception unit that receives position information of a capturing target and a captured image of the capturing target captured by at least one camera, a prediction unit that predicts a position of the capturing target within a capturing range of the camera based on the position information of the capturing target; a detection unit that detects the capturing target by reading a captured image of a limitation range that is a part of the capturing range from the captured image of the capturing range based on a predicted position of the capturing target; a measurement unit that measures a position of a detected capturing target; and an output unit that outputs a difference between a measured position of the capturing target and the predicted position.

Abstract: Projection device switches and projects a plurality of types of pattern images in a unit of projection frame. Imaging device images object to which the pattern image is projected and generates image data. Measurement device discriminates whether each imaging frame is a key frame of the image data obtained by capturing one of the pattern images or a blended frame of the image data obtained by capturing a plurality of the pattern images switched during an exposure period of one frame, and performs measurement based on a space coding method by using at least the image data of the key frame.

Abstract: A mounting machine includes a first imaging unit that captures, as a first captured image, a first imaging region in a predetermined imaging region on a substrate illuminated with laser light, the first imaging region being smaller than the predetermined imaging region, a second imaging unit that captures, as a second captured image, a second imaging region in the predetermined imaging region, the second imaging region smaller than the predetermined imaging region and including at least a region different from the first imaging region, and a calculation unit that detects an illumination position of the laser light from at least one captured image of the first captured image or the second captured image, and calculates a height of the substrate based on the detected illumination position.

Abstract: A projection system includes a projection apparatus configured to perform position measurement and projection on a target object. The projection apparatus includes: an invisible light projector configured to project measurement light of invisible light onto the target object; a light receiver configured to receive reflected light of the measurement light reflected from the target object; and a calculator configured to calculate position information of the target object based on the reflected light of the measurement light. The calculator is configured to perform a mask processing of limiting a part of a projection range in which the measurement light is projected.

Abstract: A projection system includes a plurality of projection devices configured to perform position measurement and projection on a target object. Each of the projection devices includes: an invisible light projection unit configured to project invisible measurement light onto the target object; a light receiving unit configured to receive reflection light of the measurement light, the reflection light being reflected from the target object; a computing unit configured to calculate position information of the target object on the basis of the reflection light of the measurement light; and a visible light projection unit configured to project a visible light video content on the basis of the position information of the target object. A first projection device and a second projection device of the plurality of projection devices project the measurement light at different projection timings.

Abstract: A projection system for projecting an image comprises: a visible light projector that projects the image with visible light; an invisible light projector that projects an invisible light image onto the object with invisible light; an imaging device that captures the invisible light image projected from the invisible light projector; and a controller that obtains information regarding reflected light from the object while obtaining three-dimensional measurements of the object to control the image, based on a capture image. The invisible light image includes a bright region and a dark region having a light amount less than the light amount of the bright region. The invisible light projector emits the invisible light to cause the light amount of the dark region in the invisible light image to be more than or equal to an offset value.

Abstract: An image projection system includes an infrared ray projection apparatus that projects a pattern image for shape measurement toward a projection target, an imaging device that captures the pattern image, a calculation device that acquires three-dimensional shape information of the projection target based on the captured pattern image and converts a content image into a projection content image corresponding to the projection target based on the three-dimensional shape information, and a visible light projection apparatus that is disposed in a different position from the infrared ray projection apparatus and projects the projection content image toward the projection target, in which the calculation device, based on images of a visible light image projected by the visible light projection apparatus and a non-visible light image projected by the infrared ray projection apparatus, executes processing of associating each pixel of the non-visible light image with each pixel of the visible light image.

Abstract: A projection adjustment program which causes a computer to execute a process relating to adjustment of projection operations of a plurality of projection devices configured to perform position measurement and projection on a target object in a projection system including the plurality of projection devices. The process includes: causing a projection device to project measurement light onto the target object; causing an image capture device to receive reflection light of the measurement light, the reflection light being reflected from the target object; judging a connection relationship of a projection range of the projection device on a basis of the received reflection light of the measurement light; executing a process of the judging of the connection relationship on all processing target projection devices; generating projection position information indicating a connection relationship between projection ranges of the respective projection devices of the projection system; and displaying the generated projection position information on a display.
