Abstract: The present disclosure relates to a signal processing apparatus, a signal processing method, a program, and an object detection system that enable an object detection to be accurately performed. A stereo camera performs imaging by a right camera and a left camera to thereby acquire a stereo image and a millimeter wave radar acquires a radar image in which a position of an object is detected in a radiation range of millimeter waves by using millimeter waves that are radio waves of a millimeter wave band. Then, by communication via a communication apparatus with a target in which positional information is known, it is determined whether or not the target is reliable, and in a case where it is determined that the target is reliable, calibration processing is performed for eliminating a deviation in coordinate systems generated in the stereo image and the radar image in which the target is detected. For example, the present technology can be applied to an on-vehicle sensor mounted on a vehicle in which automatic driving control is performed.

Abstract: The present technology relates to a control device, a control method, and a program that make it possible to estimate a self-position reliably with lower power consumption. An activation determination unit selects some of a plurality of cameras as activation cameras to be used for self-position estimation; and on the basis of the selection result of the activation cameras, an activation switching unit sets cameras taken as the activation cameras among the plurality of cameras to an activation state and causes the cameras to photograph images, and suspends the activation of the other cameras. A self-position estimation unit performs self-position estimation on the basis of images photographed by the activation cameras. Further, the activation determination unit selects the activation cameras again at a predetermined timing. The present technology can be applied to a self-position estimation system.

Abstract: A normal-line information generation block 30 generates normal-line information for a frame subject to detection. A data storage block 50 stores normal-line information and the like of a key frame. A motion amount detection block 40 detects a motion amount of an imaging position of the frame subject to detection relative to an imaging position of the key frame on the basis of the normal-line information of the key frame stored in the data storage block 50 and the normal-line information of the frame subject to detection generated by the normal-line information generation block 30. Even if a positional difference of a same point is small or a luminance difference occurs between a taken image of the key frame and a taken image of a current frame, a motion amount of the imaging position of the frame subject to detection relative to the imaging position of the key frame can be accurately detected on the basis of normal-line information. Therefore, an observation position can be accurately detected.
